CentOS installation LNMP environment and VSFTP service configuration

Nginx's support is high concurrency, strong load balancing, low resource consumption makes it the first choice for Linux Web server, especially for small memory VPS, this is more obvious, make it win Apache.

The installation of LNMP is described below.
1. Preparatory work

Modify Login Password: <<linux Modify user Password >>

Modify time zone and time: << Modify Linux system time zone and time >>

Close redundant TTY channels

The code is as follows	Copy Code
Vi/etc/init/start-ttys.conf Find tty[1-6] change into tty[1-2] Find Active_consoles=/dev/tty[1-6] Change into active_consoles=/dev/tty[1-2]

After reboot, you can

Modify Host Name: << Modify Linux host name (hostname) >>

Add Yum source and update: <<centos add common yum source >> configuration

iptables firewall, open the necessary ports:

The code is as follows

Copy Code

Vi/etc/sysconfig/iptables # generated by Iptables-save v1.4.7 on Sat Sep 29 10:26:10 2012 *nat :P rerouting ACCEPT [40,182:3,767,364] :P ostrouting ACCEPT [11,964:943,507] : OUTPUT ACCEPT [11,964:943,507] -A postrouting-s 192.168.0.0/24-o eth0-j Masquerade COMMIT # Completed on Sat Sep 29 10:26:10 2012 # generated by Iptables-save v1.4.7 on Sat Sep 29 10:26:10 2012 *filter : INPUT DROP [4:600] : FORWARD DROP [0:0] : OUTPUT DROP [0:0] -A input-p gre-j ACCEPT -A input-i lo-j ACCEPT -A input-p tcp-m tcp--dport 20-j ACCEPT -A input-p tcp-m tcp--dport 21-j ACCEPT -A input-p tcp-m state--state new-m TCP--dport 22-j ACCEPT -A input-p tcp-m tcp--dport 443-j ACCEPT -A input-p tcp-m tcp--dport 80-j ACCEPT -A input-p tcp-m tcp--dport 1723-j ACCEPT -A input-p tcp-m tcp--dport 3306-j ACCEPT -A input-p tcp-m tcp--dport 30000:35000-j ACCEPT -A input-p tcp-m tcp--dport 65535-j ACCEPT -A input-p icmp-m ICMP--icmp-type any-j ACCEPT -A input-m state--state related,established-j ACCEPT -A forward-s 192.168.0.0/24-o eth0-j ACCEPT -A forward-d 192.168.0.0/24-i eth0-j ACCEPT -A output-m state--state new,related,established-j ACCEPT

2. Install Nginx

List all versions of Nginx

The code is as follows	Copy Code
Yum List Nginx

You can see that the latest version is 1.5.2

The code is as follows	Copy Code
Yum Install Nginx

Start Nginx

The code is as follows	Copy Code
Service Nginx Start

Set to boot

The code is as follows	Copy Code
Chkconfig--level 3 Nginx on

Visit the VPS domain or IP if the display Welcome to nginx! Page to indicate that the installation was successful.

Nginx's web site root is different from Apache, for/usr/share/nginx/html
Configuration file is located in/etc/nginx
3. Install MySQL

This is the same as the MySQL installation under the LAMP environment. Refer to <<centos installation mysql>>
The latest version is 5.5.31

4. Install PHP

According to user testing, PHP 5.4 than PHP 5.3 performance increased by more than 50%, so here is recommended to use PHP 5.4 and updated version.

List the latest version of PHP because the webtatic source is usually up to date, so we only look in webtatic.

Yum List--disablerepo=*--enablerepo=webtatic php*

You can see that the latest version is PHP 5.5, but since Zend Guard Loader currently only supports PHP 5.4, we install the PHP 5.4 version.

Install PHP 5.4 and related components (additions and deletions according to your own needs)

Here, the PHP54W-FPM is used to associate with the Nginx module, so it is necessary, which is different from the LAMP environment

The code is as follows	Copy Code
Yum install php54w php54w-fpm php54w-bcmath php54w-cli php54w-common php54w-gd php54w-imap php54w-intl php54w-ldap php54w -mbstring php54w-mcrypt php54w-mysql php54w-odbc php54w-pdo php54w-pear Php54w-pspell php54w-soap php54w-xml Php54w-xmlrpc

If the httpd service is started, deactivate the service.

The code is as follows	Copy Code
Service httpd Stop Chkconfig httpd off

Start the PHP-FPM service

The code is as follows	Copy Code
Service PHP-FPM Start

Configure Nginx to use PHP-FPM

The code is as follows	Copy Code
Vi/etc/nginx/conf.d/default.conf

Find the following content

The code is as follows	Copy Code
Location/{ root/usr/share/nginx/html; Index index.html index.htm; }

can modify root to other directories
Add the index.php type to the index entry

The code is as follows	Copy Code
Location/{ root/usr/share/nginx/html; Index index.html index.htm index.php; }

Remove the comments from the following content

The code is as follows	Copy Code
#location ~ php$ { # root HTML; # Fastcgi_pass 127.0.0.1:9000; # Fastcgi_index index.php; # Fastcgi_param Script_filename/scripts$fastcgi_script_name; # include Fastcgi_params; #}

Modify the Fastcgi_param entry to replace the/scripts with the root content in location, which is the site root directory

The code is as follows	Copy Code
Location ~. php$ { root HTML; Fastcgi_pass 127.0.0.1:9000; Fastcgi_index index.php; Fastcgi_param Script_filename/usr/share/nginx/html$fastcgi_script_name; Include Fastcgi_params; }

Save exit

Edit PHP.ini

The code is as follows	Copy Code
Vi/etc/php.ini

The maximum allowable upload value is changed to 8M.

The code is as follows	Copy Code
Post_max_size = 8M Upload_max_filesize = 8M

Setting up Boot

The code is as follows	Copy Code
Chkconfig--level 3 php-fpm on

Restart Nginx and PHP-FPM services

The code is as follows	Copy Code
Service Nginx Restart Service PHP-FPM Restart

Create a new phpinfo.php file in/usr/share/nginx/html

The code is as follows	Copy Code
vi/usr/share/nginx/html/phpinfo.php <?php Phpinfo (); ?>

If displayed correctly, the installation is successful.

5. Install Vsftp

Configuring the FTP Service
1. Install Vsftp

The code is as follows	Copy Code
Yum Install vsftpd

Edit configuration file

The code is as follows	Copy Code
Vi/etc/vsftpd/vsftpd.conf

We use the form of a virtual user here, configured as follows.

The code is as follows

Copy Code

Anonymous_enable=no Local_enable=yes Write_enable=yes local_umask=022 Dirmessage_enable=yes Xferlog_enable=yes Xferlog_file=/var/log/vsftpd.log Connect_from_port_20=yes Ftpd_banner=welcome to my FTP Server ^_^. Chroot_local_user=yes Ls_recurse_enable=yes Listen=yes Pam_service_name=vsftpd Userlist_enable=no Tcp_wrappers=yes One_process_model=no #以下是手动添加的 pasv_min_port=30000 pasv_max_port=35000 Allow_writable_root=yes Guest_enable=yes Guest_username=root Virtual_use_local_privs=yes User_config_dir=/etc/vsftpd/user_conf

2. Generate vsftpd Virtual user database files:

To create a virtual user list file:

The code is as follows	Copy Code
Vi/etc/vsftpd/ftpuser.txt

The contents are as follows:

The code is as follows	Copy Code
Ftp1 1234 Ftp2 5678

The format is simple: "A line of user name, one line password!" ”。
3. Generate virtual user data files:

The code is as follows	Copy Code
Db_load-t-T Hash-f/etc/vsftpd/ftpuser.txt/etc/vsftpd/users.db chmod 600/etc/vsftpd/users.db

4. Configure PAM Authentication file:

The code is as follows	Copy Code
Vi/etc/pam.d/vsftpd

Annotate or delete the original content and add the following to the file.
32-bit system:

The code is as follows	Copy Code
#db =/etc/vsftpd/users, the users here are the database names that were created in the previous step, removing the suffix. Auth required/lib/security/pam_userdb.so db=/etc/vsftpd/users Account Required/lib/security/pam_userdb.so Db=/etc/vsftpd/users

64-bit system:

The code is as follows	Copy Code
#db =/etc/vsftpd/users, the users here are the database names that were created in the previous step, removing the suffix. Auth required/lib64/security/pam_userdb.so db=/etc/vsftpd/users Account Required/lib64/security/pam_userdb.so Db=/etc/vsftpd/users

5. Create a virtual user-independent configuration file

Each virtual user must have a profile that is the same as the user name, which holds the personalization configuration for the user, which can be any property in the vsftpd.conf.

Create a virtual user profile directory, which is user_config_dir= configured in vsftpd.conf.

Mkdir/etc/vsftpd/user_conf

Create a user profile, named after the user name.

The code is as follows	Copy Code
Vi/etc/vsftpd/user_conf/ftp1 Local_root=/var/www/html idle_session_timeout=600 data_connection_timeout=120 max_clients=10 Max_per_ip=5 local_max_rate=50000

6. Start Service

The code is as follows	Copy Code
Service VSFTPD Start

Setting up Boot

The code is as follows	Copy Code
Chkconfig--level 3 vsftpd on

7. Allow through firewall

The code is as follows	Copy Code
Iptables-a input-p tcp-m TCP--dport 20-j ACCEPT Iptables-a input-p tcp-m TCP--dport 21-j ACCEPT Iptables-a input-p tcp-m TCP--dport 30000:35000-j ACCEPT

At this point, the FTP service configuration is complete, try it with the client connection.
