1、什么是LAMP
LAMP=linux+apache+mysql+php
Apache是一种web服务器。mysql是一种小型数据库。php是一种语言，可以写网站程序。
静态网页和动态网页的区别是否涉及数据库。
rpm包类似于windows的.exe程序，依赖平台redhat、centos。源码包大多是C语言写的，是看得见的、可以更改，且不依赖于平台。
2、安装mysql（按顺序安装）
（1）下载mysql-5.1.40-linux-i686-icc-glibc23.tar.gz 二进制免编译包
[root@localhost ~]# cd /usr/local/src/ //默认将安装包放在此目录 [root@localhost src]# wget http://syslab.comsenz.com/downloads/linux/mysql-5.1.40-linux-i686-icc-glibc23.tar.gz //下载32位mysql免编译包 --2014-04-16 09:13:27-- http://syslab.comsenz.com/downloads/linux/mysql-5.1.40-linux-i686-icc-glibc23.tar.gz Resolving syslab.comsenz.com... 180.153.5.50 Connecting to syslab.comsenz.com|180.153.5.50|:80... connected.

[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql Installing MySQL system tables... ERROR: 1004 Can't create file '/tmp/#sql52f_1_0.frm' (errno: 13) #出现这种问题，解决方法如下： [root@localhost mysql]# chmod -R 777 /tmp 再重新初始化 [root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql Installing MySQL system tables... OK Filling help tables... OK //出现两个ok就是初始化成功
（8）定义配置文件
[root@localhost support-files]# ls //配置文件模板 binary-configure my-huge.cnf mysqld_multi.server config.huge.ini my-innodb-heavy-4G.cnf mysql-log-rotate config.medium.ini my-large.cnf mysql.server config.small.ini my-medium.cnf ndb-config-2-node.ini magic my-small.cnf [root@localhost support-files]# cp my-huge.cnf /etc/my.cnf cp: overwrite `/etc/my.cnf'? y //mysql配置文件默认放在/etc/my.cnf
（9）修改配置文件
[root@localhost support-files]# vim /etc/my.cnf key_buffer_size = 128M //128M实验环境足够用了 #log-bin=mysql-bin //主生成二进制文件，从读取二进制文件
（10）定义启动脚本并添加到服务
[root@localhost support-files]# cp mysql.server /etc/init.d/mysqld //拷贝文件到/etc/init.d目录下 [root@localhost support-files]# chmod 755 /etc/init.d/mysqld //修改权限 [root@localhost support-files]# chkconfig --add mysqld //添加服务 [root@localhost support-files]# chkconfig --list |grep mysqld mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off //查看服务，0-6表示运行级别，off和on表示所在的运行级别此服务的开启还是关闭。
（11）指定datadir
[root@localhost support-files]# vim /etc/init.d/mysqld datadir=/data/mysql
（12）启动mysql
[root@localhost mysql]# /etc/init.d/mysqld start Starting MySQL.. SUCCESS! //启动成功

扩展学习
1、什么是扩展模块
apxs是一个为Apache HTTP服务器编译和安装扩展模块的工具，用于编译一个或多个源程序或目标代码文件为动态共享对象，使之可以用由mod_so提供的LoadModule指令在运行时加载到Apache服务器中。在Apache的配置文件中西东增加一行配置文件。
编译二进制文件的时候，所加载的一些模块，所有的可执行文件都会依赖一些包或库，这些库是由一些小模块。加载库的两种形式，一是所有模块全部直接编译进二进制文件中，但文件会越来越大，耗费资源。二是暂时编译进去一些常用的模块到二进制文件中，不常用的以扩展模块的形式加载。需要指定扩展模块的路径。
2、添加扩展模块
（1）Apache安装扩展模块 - mod_status
[root@localhost generators]# /usr/local/apache2/bin/apxs -i -a -c -n statuts mod_status.c [root@localhost generators]# vim /usr/local/apache2/conf/httpd.conf LoadModule deflate_module modules/mod_deflate.so LoadModule expires_module modules/mod_expires.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule php5_module modules/libphp5.so LoadModule statuts_module modules/mod_status.so #自动添加
（2）PHP扩展模块安装 - memcache
[root@localhost src]# wget http://www.lishiming.net/data/p_w_upload/forum/memcache-2.2.3.tgz [root@localhost src]# tar -zxvf memcache-2.2.3.tgz [root@localhost src]# cd memcache-2.2.3 [root@localhost memcache-2.2.3]# /usr/local/php/bin/phpize Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script. [root@localhost memcache-2.2.3]# yum install m4 [root@localhost memcache-2.2.3]# yum install autoconf [root@localhost memcache-2.2.3]# /usr/local/php/bin/phpize Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 [root@localhost memcache-2.2.3]# ./configure --with-php-config=/usr/local/php/bin/php-config [root@localhost memcache-2.2.3]# make && make install [root@localhost memcache-2.2.3]# cp /usr/local/src/php-5.3.27/php.ini-development /usr/local/php/etc/php.ini [root@localhost memcache-2.2.3]# vim /usr/local/php/etc/php.ini extension = memcache.so
3、常用技巧
（1）查看Apache编译参数
[root@localhost etc]# cat /usr/local/apache2/build/config.nice #! /bin/sh # # Created by configure "./configure" \ "--prefix=/usr/local/apache2" \ "--with-included-apr" \ "--enable-deflate=shared" \ "--enable-expires=shared" \ "--enable-rewrite=shared" \ "--with-pcre" \ "$@"
（2）查看Apache加载的
[root@localhost modules]# /usr/local/apache2/bin/apachectl -M
（3）重新加载配置文件
[root@localhost modules]# /usr/local/apache2/bin/apachectl graceful httpd not running, trying to start
（4）查看mysql的配置参数
[root@localhost modules]# cat /usr/local/mysql/bin/mysqlbug|grep configure # This is set by configure CONFIGURE_LINE="./configure '--prefix=/usr/local/mysql' '--localstatedir=/usr/local/mysql/data' '--libexecdir=/usr/local/mysql/bin' '--with-comment=MySQL Community Server (GPL)' '--with-server-suffix=' '--enable-thread-safe-client' '--enable-local-infile' '--enable-assembler' '--with-pic' '--with-fast-mutexes' '--with-client-ldflags=-static' '--with-mysqld-ldflags=-static' '--with-zlib-dir=bundled' '--with-big-tables' '--with-readline' '--with-embedded-server' '--with-partition' '--with-innodb' '--without-ndbcluster' '--with-archive-storage-engine' '--with-blackhole-storage-engine' '--with-csv-storage-engine' '--without-example-storage-engine' '--with-federated-storage-engine' '--with-extra-charsets=complex' 'CC=icc -static-intel -static-libgcc' 'CFLAGS=-g -O3 -unroll2 -ip -mp -restrict' 'CXX=icpc -static-intel -static-libgcc' 'CXXFLAGS=-g -O3 -unroll2 -ip -mp -restrict'"
（5）查看php编译参数
[root@localhost modules]# /usr/local/php/bin/php -i |head phpinfo() PHP Version => 5.3.27 System => Linux localhost.localdomain 2.6.32-358.el6.i686 #1 SMP Thu Feb 21 21:50:49 UTC 2013 i686 Build Date => Apr 16 2014 11:23:29 Configure Command => './configure' '--prefix=/usr/local/php' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-config-file-path=/usr/local/php/etc' '--with-mysql=/usr/local/mysql' '--with-libxml-dir' '--with-gd' '--with-jpeg-dir' '--with-png-dir' '--with-freetype-dir' '--with-iconv-dir' '--with-zlib-dir' '--with-bz2' '--with-openssl' '--with-mcrypt' '--enable-soap' '--enable-gd-native-ttf' '--enable-mbstring' '--enable-sockets' '--enable-exif' '--disable-ipv6' Server API => Command Line Interface Virtual Directory Support => disabled Configuration File (php.ini) Path => /usr/local/php/etc Loaded Configuration File => /usr/local/php/etc/php.ini
（6）查看php的加载模块
[root@localhost modules]# /usr/local/php/bin/php -m [PHP Modules] bz2 Core ctype date dom ereg
（7）查看php.ini文件在那里
[root@localhost modules]# /usr/local/php/bin/php -i |grep 'Configuration File' Configuration File (php.ini) Path => /usr/local/php/etc Loaded Configuration File => /usr/local/php/etc/php.ini
（8）查看extension_dir路径
[root@localhost modules]# /usr/local/php/bin/php -i |grep 'extension_dir' PHP Warning: Unknown: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Chongqing' for 'CST/8.0/no DST' instead in Unknown on line 0 extension_dir => /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626 => /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626 sqlite3.extension_dir => no value => no value
（9）查看php依赖的库
[root@localhost modules]# ldd /usr/local/php/bin/php
linux-gate.so.1 => (0x00d51000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x001a6000)
librt.so.1 => /lib/librt.so.1 (0x003ec000)
