FTP Service Setup and configuration

Introduction to FTP

FTP is the abbreviation for the file Transfer Protocol (document Transfer Protocol), which is used to control the two-way transmission of files over the Internet.

The primary role of FTP is to have the user connect to a remote computer (which runs an FTP server program), view the files on the remote computer, and then copy the files from the remote computer to the local computer, or transfer the files from the local computer to the remote computer.

Small companies use more, large enterprises without FTP, because unsafe.

Using VSFTPD to build an FTP service

Bring your own vsftpd on CentOS

Installation: Yum install-y vsftpd

Create a User: Useradd-s/sbin/nologin virftp//-s Specify his shell so for the sake of security, the purpose of creating this ordinary user is to allow these virtual users to do a mapping, because you want to log on to this machine to transfer data, so you need a user

Edit file: Vim/etc/vsftpd/vsftpd_login//This file we call the virtual user's password file, need to define his user name and password, odd behavior user name, even behavior password, multiple users write multiple lines, the content format is as follows:

TestUser1

Aminglinux

User1

987654321

Edit Change Permissions: chmod 600/etc/vsftpd/vsftpd_login cannot be read by all users

Convert the text password file to a computer-recognized binary: db_load-t-T hash-f/etc/vsftpd/vsftpd_login/etc/vsftpd/vsftpd_login.db

directory where the virtual user configuration file is created: mkdir/etc/vsftpd/vsftpd_user_conf

This directory is also custom, so go to the config file to define

Go to this directory first: cd/etc/vsftpd/vsftpd_user_conf

Create and edit a user's profile: Vim TestUser1// Create user profile to match your user name, Add the following://comment

local_root=/home/virftp/testuser1//define a virtual user's home directory

anonymous_enable=no//whether to allow secret users

write_enable=yes//whether writable is allowed

local_umask=022//what is the right to create a new directory for a new file, consistent with the system

anon_upload_enable=no//allow secret users to upload

anon_mkdir_write_enable=no//allow secret users to create directories and write

idle_session_timeout=600//How much time the upload is out of date disconnect

data_connection_timeout=120//data transfer out of time

max_clients=10//the maximum number of clients

Create a virtual user's home directory: Mkdir/home/virftp/testuser1

In touch a file: Touch/home/virftp/testuser1/aming.txt

Change permissions: Chown-r virftp:virftp/home/virftp because finally you want to map to virftp this user

Edit the configuration file, define its password file where: vim/etc/pam.d/vsftpd//At the front Plus

Auth sufficient/lib64/security/pam_userdb.so Db=/etc/vsftpd/vsftpd_login

Account Sufficient/lib64/security/pam_userdb.so Db=/etc/vsftpd/vsftpd_login

Edit VFSTPD's master profile: vim/etc/vsftpd/vsftpd.conf

Change Anonymous_enable=yes to Anonymous_enable=no do not allow secret users

Change #anon_upload_enable=yes to Anon_upload_enable=no

Change #anon_mkdir_write_enable=yes to Anon_mkdir_write_enable=no

At the bottom, add the following:

Chroot_local_user=yes

Guest_enable=yes

Guest_username=virftp

Virtual_use_local_privs=yes

User_config_dir=/etc/vsftpd/vsftpd_user_conf

Allow_writeable_chroot=yes

Systemctl start vsftpd//Start VSFTPD Service

Test FTB

Installing the Client software: Yum install-y lftp

lftp [email protected]

Execute command LS to see if normal output

viewing logs/var/log/messages and/var/log/secure if not normal

Install FileZilla client software under Windows and test

Use PURE-FTBD to build FTB service

Yum Install-y epel-release

Yum Install-y pure-ftpd

Change the configuration file: vim/etc/pure-ftpd/pure-ftpd.conf//find pureftpd.pdb This line, the beginning of the # Delete

Stop this service: Systemctl stop vsftpd

Start service: Systemctl start pure-ftpd

Create Test Catalog: mkdir/data/ftp

Create a normal directory: Useradd-u 1010 PURE-FTP

Change the genus group: Chown-r pure-ftp:pure-ftp/data/ftp

PURE-PW useradd ftp_usera-u pure-ftp-d/data/ftp

PURE-PW MKDB

Create a test file: Touch/data/ftp/123.txt

Login: lftp [email protected] LS to see if there are 123.txt files

PURE-PW list/userdel/usermod/passwd

Tomcat Configuration

about Tomcat

1.Tomcat is a core project of the Apache Software Foundation (Apache Software Foundation) Jakarta Project, developed by Apache, Sun, and other companies and individuals.

2.java program written by TOMCAT+JDK to run the website

3.tomcat is a middleware that really works, parsing Java scripts is the JDK

4.JDK (Java Development Kit) is the core of the entire Java, which contains the Java Runtime environment and a stack of Java-related tools as well as the Java Foundation Library.

5. The most mainstream JDK is the JDK released by Sun, in addition to the fact that IBM has published Jdk,centos can also be installed with Yum OpenJDK

Installing the JDK

JDK version 1.6,1.7,1.8

Official website http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Download the jdk8 and put it in the/usr/local/src/directory

Steps:

1. Advanced to: cd/usr/local/src/directory

2. Then transfer to Linux with Xftp

3. Unzip the JDK file: Tar zxvf jdk-8u144-linux-x64.tar.gz

4. Put it in the usr/local/directory and rename it to JDK1.8:MV jdk1.8.0_144/usr/local/jdk1.8

5. Edit the configuration file (set environment variable): vi/etc/profile//Last Face increase

java_home=/usr/local/jdk1.8/

Java_bin=/usr/local/jdk1.8/bin

Jre_home=/usr/local/jdk1.8/jre

Path= $PATH:/usr/local/jdk1.8/bin:/usr/local/jdk1.8/jre/bin

Classpath=/usr/local/jdk1.8/jre/lib:/usr/local/jdk1.8/lib:/usr/local/jdk1.8/jre/lib/charsets.jar

6. Entry into force: Source/etc/profile

7. Verify that the installation is successful: Java-version the following results prove that the installation was successful

Installing Tomcat

Go to: Cd/usr/local/src directory:

Download Tomcat:wget http://apache.fayea.com/tomcat/tomcat-8/v8.5.20/bin/apache-tomcat-8.5.20.tar.gz

Decompression: Tar zxvf apache-tomcat-8.5.20.tar.gz

Move it to the local/directory and change it to the name TOMCAT:MV Apache-tomcat-8.5.20/usr/local/tomcat

Start tomcat:/usr/local/tomcat/bin/startup.sh (Close:/usr/local/tomcat/bin/startdown.sh)

View process: PS aux|grep java PS aux|grep Tomcat

View listening ports: NETSTAT-LNTP |grep java 650) this.width=650; src= https://s1.51cto.com/wyfs02/M01/01/E5/ Wkiom1meu1ca8yx2aab-kvguhny210.png "title=" 5nw7 (oubvd9fahcpjk5~m}v.png "alt=" Wkiom1meu1ca8yx2aab-kvguhny210.png " />

Three port 8080 is the port that provides the Web service, 8005 is the management port, and 8009 port is the port that is called by the third-party service, such as httpd and Tomcat.

Tomcta supports custom ports , such as you want to change 8080 to 80 port, as follows:

Configure the Tomcat listener port to be 80 methods:

Edit the Tomcat profile: Vim/usr/local/tomcat/conf/server.xml Search: 8080

Connector port= "8080" protocol= "http/1.1" modified to Connector port= "" "Protocol=" http/1.1 "

Restart Service Tomcat:

Closed First:/usr/local/tomcat/bin/shutdown.sh

Restart:/usr/local/tomcat/bin/startup.sh

To see if there is a listening 80 port: NETSTAT-LNTP |grep Java

If there is no 80 port, see if the Java process is turned on: PS aux |grep java

To see if there are 80 ports: NETSTAT-LNTP |GREP 80 has and displays nginx occupancy, you need to turn off Nginx service:

650) this.width=650; "src=" Https://s5.51cto.com/wyfs02/M01/A0/A3/wKioL1mev-jjiVThAABw2RCIFjc974.png "title=" Irhua R X[0lel{1glcmys0.png "alt=" Wkiol1mev-jjivthaabw2rcifjc974.png "/>/etc/init.d/nginx stop

Then restart the Tamcat service, in the view:

/usr/local/tomcat/bin/shutdown.sh

/usr/local/tomcat/bin/startup.sh

Configure the virtual host for Tomcat

Edit configuration file: Vim/usr/local/tomcat/conf/server.xml search:

650) this.width=650; "src=" Https://s2.51cto.com/wyfs02/M01/03/C7/wKiom1mf6VigHumzAAAwSLx_HcE867.png "title=" 33x3q }}9 (o9@yr_7}37v (qt.png "alt=" Wkiom1mf6vighumzaaawslx_hce867.png "/>

Where the configuration between <Host> and </Host> is the virtual Host configuration section, name defines the domain name,

AppBase defines the application's directory, Java's application is usually a jar of compressed packets, you just need to put the jar's compressed package under the AppBase directory. The Tomcat default page just Amin access is actually under the AppBase directory, but in its subdirectory root.

Add virtual hosts, edit Server.xml, and add the following to the bottom </Host> below:

unpackwars= "True " autodeploy= "true"

Xmlvalidation= "false" Xmlnamespaceaware= "false" >

<context path= "" docbase= "/data/wwwroot/123.cn/" debug= "0" reloadable= "true" crosscontext= "true"/>

</Host>

DocBase, this parameter is used to define the Web site's file storage path, if not defined, the default is under the Appbase/root, the definition of docBase is based on this directory, where AppBase and docBase can be the same. In this step of the process, many students have encountered the problem of access 404, in fact, docbase is not defined.

AppBase the directory for the application, usually it needs to put the war package directly under the directory, it will be automatically extracted into a program directory

Below we realize the role of the AppBase and Docbase directories by deploying a Java application

Create a blog:

1. Download Zrlog:wget Http://dl.zrlog.com/release/zrlog-1.7.1-baaecb9-release.war

2. Move the installation package to the WebApps directory: CP zrlog-1.7.1-baaecb9-release.war/usr/local/tomcat/webapps/

3. go to the WebApps directory: cd/usr/local/tomcat/webapps/

4. Change the directory for automatic decompression to the name ZRLOG:MV zrlog-1.7.1-baaecb9-release zrlog

5. Check if MySQL is turned on: PS aux |grep MySQL

6. Log in with your computer: 192.168.65.135/zrlog/

7. Login mysql:mysql-uroot-p123456789

8. creating a library called Zrlog: Create Database Zrlog;

9. Create a user, specify the user's IP and password: Grant all on zrlog.* to ' Zrlog ' @127.0.0.1 identified by ' 12345678 '; To : Specify IP identified by: Specify Password

Ten. Create a complete check to create a user right: mysql-uzrlog-h127.0.0.1-p12345678

See if there are any zrlog:show databases;

Edit Page zrlog info: Next-next-finish

Visit URL: 192.168.65.135/zrlog/

If you do not want to access IP directly, you need to do the following:

AppBase: Is the docBase to put the war package: directly put the website program

Create directory: mkdir/data/wwwroot/123.cn

Move everything under the Zrlog directory to the 123.cn directory:

mv/usr/local/tomcat/webapps/zrlog/*/data/wwwroot/123.cn/

On the hosts that are bound on Windows

Restart Service:/usr/local/tomcat/bin/shutdown.sh

/usr/local/tomcat/bin/startup.sh

Visit URL: www.123.cn

Tomcat Log

Log in:/usr/local/tomcat/logs directory

Ls/usr/local/tomcat/logs

650) this.width=650; "src=" Https://s5.51cto.com/wyfs02/M00/A2/7B/wKioL1mgHh_hs_wnAADEKAamUBI661.png "title=" j}3w{ "SZ8" Yxidf08iamuo.png "alt=" Wkiol1mghh_hs_wnaadekaamubi661.png "/>1. The log that begins with Catalina is the synthetic log of Tomcat, which records information about the Tomcat service and logs the error log.

2. where Catalina.2017-xx-xx.log and catalina.out content are the same, the former generates a new log every day.

3.Host-manager and manager are management-related logs, where Host-manager is the management log for the virtual host.

4.localhost and localhost_access are virtual host-related logs, where the log with access is the access log, and the error log for the default virtual host without the word access.

Access logs are not generated by default and need to be configured in Server.xml.

The specific method is to add the following configuration to the <Host></Host> of the corresponding virtual host (if the domain name is 123.cn):

<valve classname= "Org.apache.catalina.valves.AccessLogValve" directory= "Logs"

prefix= "123.cn_access" suffix= ". Log"

pattern= "%h%l%u%t &quot;%r&quot; %s%b "/>

Prefix defines the prefix of the access log, suffix defines the suffix of the log, and the pattern defines the log format. The newly added virtual host does not generate the same localhost as the default virtual host by default. Date. log log, the error log is uniformly recorded in Catalina.out. About the Tomcat log, you need to focus on catalina.out, when there is a problem, we should first want to see it.

Resin Installation and configuration

This also need to install JDK, download from official website, caucho.com, download the first do not charge to do the experiment just fine.

First step, download the installation package: Wget http://caucho.com/download/resin-4.0.53.tar.gz

Unzip: Tar zxvf

Go to the unpacked directory and compile:./configure --prefix=/usr/local/resin --with-java=/usr/local/jdk1.8 two designations, The first one needs to specify which directory to install and the second to specify the path where Java resides

Make && make install

It will automatically generate this directory: ls/usr/local/resin/

Auto-Generate startup script: Ls/etc/init.d/resin

It's best to stop Tomcat first:/etc/init.d/tomcat stop

At startup:/etc/init.d/resin start

Visit: 192.168.65.135:8080

It defaults to port 8080, and you want direct access to the 80 port method:

Change the Listening port:

Go to the resin/conf/directory: cd/usr/local/resin/conf/

Edit profile: Vim resin.properties search: app.http change 8080 to

Restart:/etc/init.d/resin start

NETSTAT-LNP |grep Resin See if there's a 80 port.

Direct access: 192.168.65.135

Change the virtual host:

Edit Virtual Host profile: Vim Resin.xml Search: <cluster id= "App" > write down this paragraph to the back

<web-app id= "/" root-directory= "/tmp/resin"/>

Create directory: Mkdir/tmp/resin

Reboot:/etc/init.d/resin stop/etc/init.d/resin start

Take a look at Port 80: NETSTAT-LNP |grep java

Create a parse file to see if you can parse

Go to this directory: Cd/tmp/resin

Edit configuration file: Vim 1.txt Add the following:

<?php

echo "Hello how is you.";

Parse: curl-x127.0.0.1:80 www.123.com/1.txt

MySQL Master-slave configuration

Uninstall the original MySQL step

First step, go to src: cd/usr/local/src/

Step Two, delete

Rm-rf/usr/local/mysql

Rm-rf/etc/init.d/mysqld

The third step, download unzip:

wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz

Tar zxvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz

Fourth step, move the finished MySQL to MySQL directory: MV Mysql-5.6.35-linux-glibc2.5-x86_64/usr/local/mysql

Go to the MySQL directory: cd/usr/local/mysql

Check to see if there is a MySQL user: grep ' mysql '/etc/passwd

No words create one: Useradd MySQL

Create the Data directory: mkdir/data/

Compilation:./scripts/mysql_install_db--user=mysql--datadir=/data/mysql

Copy the configuration file and startup script:

CP SUPPORT-FILES/MY-DEFAULT.CNF/ETC/MY.CNF

CP Support-files/mysql.server/etc/init.d/mysqld

Edit configuration file: Vi/etc/init.d/mysqld define Basedir and DataDir

Basedir=/usr/local/mysql

Datadir=/data/mysql

Remove the previous data/mysql: Rm-rf/data/mysql

Start:/etc/init.d/mysqld start

View services: PS aux |grep MySQL

View Port: NETSTAT-LNP |grep 3306

Configuration from: Open on another machine

cd/usr/local/

Cp-r MySQL mysql_2

CD mysql_2

Define its configuration file (the configuration file should be placed in the current directory): Cp/etc/my.cnf./my.cnf

Edit configuration file: Vim my.cnf change some content

port=3306 changed into port=3307

Socket=/tmp/mysql.sock changed into Socket=/tmp/mysql2.sock

Add a sentence: datadir=/data/mysql2

Initialization operation:./scripts/mysql_install_db--user=mysql--DATADIR=/DATA/MYSQL2

Check: Whether there are two directories under ls/data/mysql_2/

Starting it requires writing a startup script:

cd/etc/init.d/

CP mysqld Mysqld2

Vim Mysqld2

Basedir=/usr/local/mysql_2

Datadir=/data/mysql_2

conf= $basedir/my.cnf

Start:/etc/init.d/mysqld2 start

View services: PS aux |grep MySQL should be there are two ports one 33,061 x 3307

Log in to two MySQL methods:

3306:mysql-uroot-s/tmp/mysql.sock or: mysql-h127.0.0.1-p3306

3307:mysql-uroot-s/tmp/mysql_2.sock or: mysql-h127.0.0.1-p3307

First login to master settings master:

Mysql

Creating a library called DB1: Create Database db1; Quit to quit when you're finished creating

Copy the MySQL library: mysqldump-uroot-s/tmp/mysql.sock mysql > 123.sql

Back in recovery: mysql-uroot-s/tmp/mysql.sock DB1 < 123.sql

Log in to master MySQL

Use DB1; View Table

Show tables; View Table Contents

To edit a profile: Vim/etc/my.cnf open the bottom two.

Server-id=1 This number is not the same as the master.

Log-bin=mysql-bin can customize the name

Restart: etc/init.d/mysqld restart

A few files starting with your custom name will be generated below ls/data/mysql/

To set the root access password for the MySQL database:

Log in to MySQL

Mysqladmin-u root-s/tmp/mysql2.sock password ' 123456 '

Mysql-u root-s/tmp/mysql2.sock-p ' 123456 '

mysql> grant replication Slave on * * to ' repl ' @ ' 127.0.0.1 ' identified by ' 123123 ';

The REPL here is for the slave end of the user to access the master-side MySQL data, the password is 123123, where the 127.0.0.1 is slave IP (because the Amin configuration of the master and slave are in the native).

Mysql> flush tables with read lock; Locks the database and does not allow changes to any data at this time

Mysql> Show master status; View status, this data is to be recorded, one will be used in the slave end of the

Set from:

Edit matching files: vim/etc/my.cnf

Server-id = 1 Change to another number

Restart: Service mysqld restart

Copy data:

Mysql-uroot-s/tmp/mysql.sock-e "CREATE Database DB1"

Mysql-uroot-s/tmp/mysql.sock db1< 123.sql

Log on to from: Mysql-uroot-s/tmp/mysql_2.sock

Stop this service: slave stop;

Change Master to master_host= ' 127.0.0.1 ', master_port=3307,

Master_user= ' Repl ', master_password= ' 123123 ',

Master_log_file= ' mysql-bin.000006 ', master_log_pos=474952;

show slave status\g; Two yes indicates success

Test Master

Unlock: Unlock tables;

In the Lord Operation:

Use DB1;

View table: Show tables;

Delete a table: drop table help_category;

On the action from: view

Use DB1;

Show tables;

See if there is help_category;

It means that what you do in your Lord will also be there, such as deleting a table to delete a library, and then deleting it from the top, but you can no longer delete the creation from the top.
