Linux self-study note--lamp simple configuration

1.HTTPD Configuration

(1) Basic settings

Listen 80 Port

Documentroot/var/www root directory

DirectoryIndex index.html Home

alias/icon/"/download/newicon" path alias

ErrorDocument 404/missing.html 404 File

Extendestatus on 220 lines, status page, define specific in 920 or so

(2) Access control

<directory "/var/www/html" >

Options Indexes FollowSymLinks

AllowOverride None

Order Allow,deny

Allow from all

</Directory>

Indexes: If the page is inaccessible, provide a list of structures that should be commented out

FollowSymLinks: If a file in the root directory is linked to a non-directory, the default is failure, setting this to leave the link out of the directory limit

AllowOverride: Whether to allow. htaccess Feature Overlay

Order:allow,deny open all, rejecting specific conditions. Deny,allow reject all, open specific conditions

Allow|deny from x.x.x.x: Allow or deny a specific URL or network segment

(3) Persistent connection

KeepAlive On|off

KeepAliveTimeout 15 default, not too high

Maxkeepaliverequests 500 default 100, maximum number of timeout requests

Pros: Handle multiple requests at a time, without having to establish a TCP request for each small picture

Cons: Large concurrent server, subsequent requests may not respond in a timely manner

(4) Mpm

Prefork: Multi-process Model

Worker: Multi-process multithreaded model

Pstree | grep ' httpd ' can see the exact difference

Configuration file: centos6/etc/sysconfig/httpd

Centos7/etc/httpd/conf.modules.d/00-mpm.conf

(5) The virtual host needs to comment out DocumentRoot

Distinguish different websites based on IP or port

<virtualhost 192.168.1.10:80>

ServerName www.mage.com

DocumentRoot '/www/mage.com/htdocs '

</VirtualHost>

-------------------------------------------------

Based on hostname, you need to set DNS or hosts file parsing

Namevirtualhost 192.168.1.10:80 Note 2.4 not required

<virtualhost 192.168.1.10:80>

ServerName www.mage.com

Document '/www/mage.com/htdocs '

</VirtualHost>

<virtualhost 192.168.1.10:80>

ServerName www.niaoge.com

Document '/www/niaoge.com/htdocs '

</VirtualHost>

2.mariadb

(1) Admin password: mysqladmin-uroot password 123

(2) Change admin password: mysqladmin-uroot-p123 Password

(3) Authorization: Grant all on dbname.tbname to ' user ' @ ' ipaddr ' identified by ' password ';

Use arbitrary data: *. *

Any address:%

(4) Modify user password:

Use MySQL;

Update user set Password=password (' 456 ') where user= ' root ';

Flush privileges;

(5) Rejection of anti-parsing/etc/my.cnf

[Mysqld]

Skip_name_resolve=on;

3. Compile and install lamp

(1) httpd

./configure--PREFIX=/USR/LOCAL/HTTPD

--sysconfdir=/etc/httpd

--WITH-APR=/USR--WITH-APR-UTIL=/USR

(2) mariadb

Copy support-files under Configuration file to/etc/mysql/my.cnf, copy Mysql.server to/etc/init.d/mysqld

Chkconfig--add mysqld

Initialize the database, use scripts/mysql_install_db--user=mysql under/usr/local/mysql--datadir=/path

(3) PHP

./configure--prefix=/usr/local/php

--with-mysql=/usr/local/mysql

--with-mysqli=/usr/local/mysql/bin/mysql_config

--with-config-file-path=/etc

--with-config-file-scan-dir=/etc/php.d

--WITH-APXS2=/USR/LOCAL/HTTPD/BIN/APXS will be compiled into modules using
