一、安装：
1、#tar -zxf nginx-1.4.2.tar.gz
2、#cd nginx-1.4.2
3、#./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx
(1)、执行后报error: the HTTP rewrite module requires the PCRE library.
是说明缺少pcre-devel包，
# rpm -qa |grep pcre
结果pcre-7.8-6.el6.x86_64，
可见缺少pcre-devel包
(2)、查看pcre-devel是否存在：yum list pcre* ，结果如下：
A、Installed Packages
pcre.x86_64 7.8-6.el6 @anaconda-CentOS-201303020151.x86_64/6.4
B、Available Packages
pcre.i686 7.8-6.el6 base_local
pcre-devel.i686 7.8-6.el6 base_local
pcre-devel.x86_64 7.8-6.el6 base_local
pcre-static.x86_64 7.8-6.el6 base_local
可见存在。
(3)、#yum install pcre-devel
4、然后在执行
#./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx，
执行结果显示了配置摘要：Configuration summary
+ using system PCRE library
+ OpenSSL library is not used
+ md5: using system crypto library
+ sha1: using system crypto library
+ using system zlib library
nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx configuration prefix: "/etc"
nginx configuration file: "/etc/nginx"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"
可见这次没报错，说明执行configure脚本成功。
5、编译#make
6、安装#make install
7、验证是否安装成功：
（1）、看/usr/local/nginx是否有文件：
# ls /usr/local/nginx,结果为：html logs sbin
（2）、看 /etc/nginx是否有文件：
# ls /etc/nginx，结果为空：安装失败。
因--conf-path指的是配置文件路径，最后需写配置文件名nginx.conf。
8、卸载：
（1）、删除安装文件：rm -rf /usr/local/nginx
（2）、删除配置文件：rm -rf /etc/nginx
9、再次在执行
#./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx/nginx.conf
执行结果显示了配置摘要：Configuration summary
+ using system PCRE library
+ OpenSSL library is not used
+ md5: using system crypto library
+ sha1: using system crypto library
+ using system zlib library
nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx configuration prefix: "/etc/nginx"
nginx configuration file: "/etc/nginx/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"
比较一下如上次的配置摘要的区别：
nginx configuration prefix: "/etc/nginx"
nginx configuration file: "/etc/nginx/nginx.conf"
10、编译并安装：#make && make install,先实行make，成功再执行make install
11、再次验证是否安装成功：
（1）、看/usr/local/nginx是否有文件：
#ls /usr/local/nginx,结果为：html logs sbin
（2）、看 /etc/nginx是否有文件：
# ls /etc/nginx，结果为：
fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params
uwsgi_params win-utf fastcgi.conf.default fastcgi_params.default koi-win
mime.types.default nginx.conf.default scgi_params.default
uwsgi_params.default
二、启动：
1、看下80端口是否被占用：
#netstat -tnl,结果无80：
2、#cd /usr/local/nginx/sbin
执行：#./nginx
3、#netstat -tnl,结果出现了80，说明启动成功：
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
4、 验证启动成功：
（1）、#在浏览器中访问http://192.168.127.161/ 可能会访问不到，因防火墙未关闭。
（2）、#service iptables stop
（3）、再次访问http://192.168.127.161/ 终于访问到了 哈哈
5、强制关闭nginx：
# killall nginx
