ubuntu 安装 lamp 环境

  今天介绍一下Linux下LAMP(Apache+PHP+MySql)环境配置:
  1、下载软件
  MySql:wget http://down1.chinaunix.net/distfiles/mysql-5.0.56.tar.gz
  Apache:wget http://apache.freelamp.com/httpd/httpd-2.2.13.tar.gz
  PHP:wget http://125.39.113.23:9203/CDE349DEF7D7A6AC19DE5771F752CA258C693F634815D4BE/cn.php.net/distributions/php-5.2.10.tar.bz2
  2、安装MySql
  安装步骤:
  shell> groupadd mysql
  shell> useradd -g mysql mysql
  shell> gunzip < mysql-VERSION.tar.gz | tar -xvf – 或 tar -zxvfmysql-5.0.56.tar.gz(解压mysql源码包)
  shell> cd mysql-VERSION(进入mysql源码文件夹)
  shell> ./configure –prefix=/usr/local/mysql
  shell> make
  shell> make install
  shell> cp support-files/my-medium.cnf /etc/my.cnf
  shell> cd /usr/local/mysql
  shell> bin/mysql_install_db –user=mysql
  shell> chown -R root.
  shell> chown -R mysql var
  shell> chgrp -R mysql .
  shell> bin/mysqld_safe –user=mysql &
  修改mysql root 密码
$ mysqladmin -u root password newpass
添加服务项
cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
chkconfig –add mysqld
  3、安装Apache
  tar zvxf httpd-2.2.13.tar.gz
cd httpd-2.2.13
修改src/include/httpd.h 增大最大线程数
  #define HARD_SERVER_LIMIT 256
  改成
  #define HARD_SERVER_LIMIT 2560
  保存退出编译apache
./configure –prefix=/usr/local/apache –enable-module=so –enable-module=rewrite –enable-shared=max –htdocsdir=/var/www &&
make
make install
  #这里我们通过enable-module参数告诉设置脚本,我们需要启动so和rewrite模块,so模块是用来提DSO支持的apache核心模块,而rewrite模块则是用意实现地址重写的模块,由于rewrite模块需要DBM支持,如果在初次安装时没有编译进apache,以后需要用到时需要重新编译整个apache才可以实现。为此除非你可以确定以后不会用到rewrite模块,否则还是建议你在第一次编译的时候把rewrite模块编译好。
  enable-shared=max 这个参数的作用时编译apache时,把除了so以外的所有apache的标准模块都编译成DSO模块。而不是编译进apache核心内。
  好了安装apache很简单的哦,启动apache看看
  /usr/local/apache/bin/apachectl start
然后 通过浏览器查看http://youhost/,如果正常则说明安装成功。
  apache设为linux服务
  cp /usr/local/apache2/bin/apachectl /etc/init.d/httpd
vi /etc/init.d/httpd
  在在#!/bin/sh后面加入下面两行
#chkconfig:345 85 15
#description: Start and stops the Apache HTTP Server.
  然后
chmod +x /etc/rc.d/init.d/httpd
chkconfig –add httpd
  4、安装PHP
  (1)tar zvxf php-5.2.10.tar.bz2
(2)cd php-5.2.10
  (3)./configure -prefix=/usr/local/php –with-config-file-path=/usr/local/php/etc -with-mysql=/usr/local/mysql –with-mysqli=/usr/local/mysql/bin/mysql_config –with-iconv-dir=/usr/local –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir=/usr –enable-xml –disable-rpath –enable-discard-path –enable-safe-mode –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –with-curlwrappers –enable-mbregex –enable-fastcgi –enable-fpm –enable-force-cgi-redirect –enable-mbstring –with-mcrypt –with-gd –enable-gd-native-ttf –with-openssl –with-mhash –enable-pcntl –enable-sockets –with-ldap –with-ldap-sasl –-with-apxs2=/usr/local/apache/bin/apxs
  (4)make
  (5)make install
  最后一步重新启动apache报如下错误:
httpd: Syntax error on line 53 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied
  原因:是Linux有一个SELinux保护模式引起的。
  解决办法:
  1关闭SELINUX的方法:
vi /etc/selinux/config 将SELINUX=enforcing 改成SELINUX=disabled 需要重启
这个方法可能会对服务器带来风险。

2不关闭SELINUX的方法:
依次执行如下命令
# setenforce 0
# chcon -c -v -R -u system_u -r object_r -t textrel_shlib_t /usr/local/apache/modules/libphp5.so
  # service httpd restart
# setenforce 1
  vi /usr/local/apache/conf/httpd.conf
  查找
  在此范围添加
  AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
  然CPOPY PHP的配置文件
  cp ../php-5.2.10/php.ini.dist /usr/local/php/lib/php.ini
  修改php.ini文件
register_globals = On
  ok!重新启动一下apache服务器
/usr/local/apache/bin/apachectl restart
  然后写个php测试页info.php:内容如下
  <?php
phpinfo();
?>
正常的话,应该能看到php的信息了,恭喜你的Apche+Mysql+PHP安装成功。
