安装Nginx的方式有很多种，这里我们还是编译源码进行安装，使用下列命令：
$ wget http://nginx.org/download/nginx-1.6.2.tar.gz
$ tar -zxvf nginx-1.6.2.tar.gz
$ cd nginx-1.6.2
$ ./configure --prefix=/usr/local/nginx
$ make
$ sudo make install
如果安装过程中出现如下错误
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=
则需要先安装pcre
$ sudo yum install pcre-devel
安装完成之后，我们的Nginx安装目录在/usr/local/nginx。 接下来修改nginx的配置文件(/usr/local/nginx/conf/nginx.conf)，使其能够处理php脚本。
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name _;
root /vagrant;
location / {
index index.html index.htm index.php;
}
location /demo {
index index.php;
if (!-e $request_filename) {
rewrite ^/demo/(.*)$ /demo/index.php?$1 last;
break;
}
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ ＼.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
}
最后，启动Nginx时，需要先启动PHP-FPM。
$ sudo /usr/local/php/sbin/php-fpm
$ sudo /usr/local/nginx/sbin/nginx
对于Nginx的重启以及关闭操作，可以使用以下命令
$ sudo /usr/local/nginx/sbin/nginx -s [reload|restart|stop]
而PHP-FPM，则麻烦一点，需要先使用ps -ef|grep php-fpm获取master process的进程ID， 再使用kill -USR2:
$ ps -ef|grep php-fpm
root 6221 1 0 02:17 ? 00:00:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)
nobody 6222 6221 0 02:17 ? 00:00:00 php-fpm: pool www
nobody 6223 6221 0 02:17 ? 00:00:00 php-fpm: pool www
vagrant 6233 1623 0 02:18 pts/0 00:00:00 grep php-fpm
$ sudo kill -USR2 6221
注意: -USR2参数为重启，-INT参数为关闭。
创建虚拟主机
[root@os11728 httpd-2.2.22]# vi /usr/local/nginx/conf/vhosts/www_finet230_cn.conf
内容如下：
server {
listen 8080;
server_name ng.fine230.cn finet85.cn;
root /var/www/root/ng_finet230_cn;
#激活/关闭自动索引
autoindex on;
#设定索引时文件大小的单位(B,KB, MB 或 GB)
#默认为on，显示出文件的确切大小，单位是bytes。
#改为off后，显示出文件的大概大小，单位是kB或者MB或者GB
autoindex_exact_size off;
#开启以本地时间来显示文件时间的功能。默认为关（GMT时间）
#默认为off，显示的文件时间为GMT时间。
#改为on后，显示的文件时间为文件的服务器时间
autoindex_localtime on;
#charset koi8-r;
location / {
index index.html index.htm index.php;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {

}

# fastcgi_index index.php;

将/var/www/root/ng_finet230_cn目录下的所有档案与子目录的拥有者皆设为www群体的使用者www :
[root@os11728 ~]# chown -R www:www /var/www/root/ng_finet230_cn
1.5. Nginx的启动与关闭
启动Nginx
[root@os11728 ~]# ulimit -SHn 65535
[root@os11728 ~]# /usr/local/nginx/sbin/nginx
停止Nginx
[root@os11728 ~]# /usr/local/nginx/sbin/nginx -s stop
或
[root@os11728 ~]# /usr/local/nginx/sbin/nginx -s quit
重启Nginx
[root@os11728 ~]# /usr/local/nginx/sbin/nginx -s reload
或
[root@os11728 ~]# kill -HUP `cat /usr/local/nginx/logs/nginx.pid`
配置开机自动启动Nginx + PHP
代码如下[root@os11728 ~]# vi /etc/rc.local
在末尾增加以下内容：
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm
/usr/local/nginx/sbin/nginx
