CentOS3 Linux 服务器环境配置以及优化详解(2)

   # useradd username
   # passwd username
   # vi /etc/passwd (将passwd文件中username的登录shell改为/bin/sh)
   # vi /etc/ssh/sshd_config (将#protocol 1,2一行改为protocol 2)
   # vi /etc/ssh/sshd_config (将#PermitRootLogin yes一行改为PermitRootLogin no)
   # vi /usr/etc/sshd_config (将#protocol 1,2一行改为protocol 2)
   # vi /usr/etc/sshd_config (将#PermitRootLogin yes一行改为PermitRootLogin no)
   # /etc/rc.d/init.d/sshd restart
[编辑]安装配置Apache+PHP+MySQL+Zend Optimizer
1) 下载软件

   # cd /usr/local/src
   # wget http://download.discuz.net/env/httpd-2.0.58.tar.bz2
   # wget http://download.discuz.net/env/mysql-standard-5.0.22-linux-i686.tar.gz
   # wget http://download.discuz.net/env/php-5.1.4.tar.bz2
   # wget http://download.discuz.net/env/ZendOptimizer-3.0.1-linux-glibc21-i386.tar.gz
2) 安装MySQL

   # tar xzvf mysql-standard-5.0.22-linux-i686.tar.gz
   # useradd mysql
   # mv mysql-standard-5.0.22-linux-i686 /usr/local/mysql
   # cd /usr/local/mysql
   # scripts/mysql_install_db --user=mysql
   # chown -R root .
   # chown -R mysql data
   # chgrp -R mysql .
   # mv data /var/lib/mysql
   # ln -s /var/lib/mysql ./data
   # cp support-files/my-large.cnf /etc/my.cnf
   # bin/mysqld_safe --user=mysql &
   # bin/mysqladmin -u root password newpassword_for_root
   # bin/mysqladmin -u root -p shutdown
   # cp support-files/mysql.server /etc/init.d/mysqld
   # chkconfig --add mysqld
   # /etc/rc.d/init.d/mysqld start
3) 编译安装Apache

   # cd /usr/local/src
   # tar xjvf httpd-2.0.58.tar.bz2
   # cd httpd-2.0.58
   # ./configure --prefix=/usr/local/apache2 --mandir=/usr/     share/man --enable-module=so --enable-deflate=shared      --enable-expires=shared  --enable-rewrite=shared      --enable-gzip --enable-cache --enable-file-cache      --enable-mem-cache --enable-disk-cache
   # make
   # make install
4) 编译安装PHP

   # cd /usr/local/src
   # tar xjvf php-5.1.4.tar.bz2
   # cd php-5.1.4
   # ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/     apache2/bin/apxs --with-zlib --with-bz2 --with-tiff-dir      --with-libxml-dir=/usr/local/libxml2 --with-gd=/usr/local/     gd2 --with-freetype-dir --with-jpeg-dir --with-png-dir      --with-ttf --enable-mbstring --with-mysql=/usr/local/mysql      --with-config-file-path=/etc --disable-ipv6 --enable-gd-     native-ttf
   # make
   # make install
   # cp php.ini-dist /etc/php.ini
5) 安装Zend Optimizer

   # cd /usr/local/src
   # tar xzvf ZendOptimizer-3.0.1-linux-glibc21-i386.tar.gz
   # ./ZendOptimizer-3.0.1-linux-glibc21-i386/install.sh
6) 整合Apache与PHP

   # vi /usr/local/apache2/conf/httpd.conf
搜索:

   DirectoryIndex index.html index.html.var
将其改为:

   DirectoryIndex index.html index.htm index.php
搜索:

   AddType application/x-gzip .gz .tgz
在下面添加一行:

   AddType application/x-httpd-php .php
保存退出后重启Apache

   # /usr/local/apache2/bin/apachectl restart
[编辑]更改Apache运行账户以及建立虚拟主机
1. 更改Apache运行账户默认情况下Apache在Linux系统上使用nobody账户运行,我们下面将要更改运行账户提升Apache的安全性和权限可控性。

   # useradd www
   # su www
   $ mkdir -p /home/www/wwwroot/discuz
   $ exit
   # vi /usr/local/apache2/conf/httpd.conf
找到:

   User nobody
   Group #-1
改为:

   User www
   Group www

2. 建立一个虚拟主机此处我们为Apache建立一个虚拟主机。

   # vi /usr/local/apache2/conf/httpd.conf
找到:
