在CentOS 5.6 中安装 Nginx + PHP5 + MySQL
nginx是俄罗斯开发人员开发的web服务器软件，其特点是运行速度快，占用内存小，CPU低消耗，使用迅速在web服务器市场上占领了一席之地，现在nginx已经成立了一家专门的公司。
在本教程中使用主机名www.baidu.org.tw，IP 地址 192.168.0.100 。这些设置可能会有所不同，所以你必须在适当情况下以取代他们。
首先安装MySQL 5，输入命令：yum install mysql mysql-server
设置开机自动启动MYSQLchkconfig --levels 235 mysqld on<br />/etc/init.d/mysqld start
现在，检查网络启用。运行netstat -tap | grep mysql
如果运行正常，应该显示：
如果没有如上显示，编辑/etc/my.cnf文件并注释掉选项跳过网络：vi /etc/my.cnf
#skip-networking
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we’ll need the current
password for the root user. If you’ve just installed MySQL, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): <– 回车
OK, successfully used password, moving on…
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] <– 回车
New password: <– 输入Root账户密码
Re-enter new password: <– 再输入一次
Password updated successfully!
Reloading privilege tables..
… Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] <– 回车
… Success!
Normally, root should only be allowed to connect from ’localhost’. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] <– 回车
… Success!
By default, MySQL comes with a database named ’test’ that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] <– 回车
- Dropping test database…
… Success!
- Removing privileges on test database…
… Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] <– 回车
… Success!
Cleaning up…
All done! If you’ve completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
安装的Nginx,输入以下命令作安装前准备：cd /etc/yum.repos.d/<br />wget http://CentOS.karan.org/kbsingh-CentOS-Extras.repo
配置文件：vi /etc/yum.repos.d/kbsingh-CentOS-Extras.repo
修改内容如下：
# pkgs in the -Testing repo are not gpg signed
[kbs-CentOS-Testing]
name=CentOS.Karan.Org-EL$releasever – Testing
gpgcheck=0
gpgkey=http://centos.karan.org/RPM-GPG-KEY-karan.org.txt
enabled=1
baseurl=http://centos.karan.org/el$releasever/extras/testing/$basearch/RPMS/
之后，我们可以安装nginx的如下：yum install nginx
然后，我们创建系统启动nginx的链接并启动它：
chkconfig --levels 235 nginx on<br />/etc/init.d/nginx start
浏览器输入您的Web服务器IP地址或主机名（如类型http://192.168.0.100），你应该看到一个空白页，说明网站已经工作 此空白主页地址（/usr/share/nginx/html/index.html，可以自己修改一下看看）：
安装PHP5yum install lighttpd-fastcgi php-cli php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-mssql php-snmp php-soap php-tidy
打开/etc/php.ini配置cgi.fix_pathinfo = 1：vi /etc/php.ini
cgi.fix_pathinfo = 1
lighttpd的FastCGI包附带的可执行文件/usr/bin/spawn-fcgi，可以看帮助：spawn-fcgi --help
