在互联网公司，Nginx可以说是标配组件，但是主要场景还是负载均衡、反向代理、代理缓存、限流等场景；而把Nginx作为一个Web容器使用的还不是那么广泛。目前Nginx最新版是1.13，最新稳定版是1.12，它具备大家公认的高性能，而Nginx开发主要是以C/C++模块的形式进行，整体学习和开发成本偏高；因此，nginxScript应运而生：可以在Nginx中使用JavaScript进行动态配置一些变量和动态脚本执行；而目前市面上用的非常成熟的扩展是将Lua和Nginx粘合的ngx_lua模块，并且将Nginx核心、LuaJIT、ngx_lua模块、许多有用的Lua库和常用的第三方Nginx模块组合在一起成为OpenResty，这样开发人员就可以安装OpenResty，使用Lua编写脚本，然后部署到Nginx Web容器中运行。从而非常轻松就能开发出高性能的Web服务。
安装Nginx
1、下载与解压
[root@juispan ~]# cd /usr/local/src [root@juispan src]# wget http://nginx.org/download/nginx-1.12.1.tar.gz --2017-08-08 21:51:30-- http://nginx.org/download/nginx-1.12.1.tar.gz 正在解析主机 nginx.org (nginx.org)... 206.251.255.63, 95.211.80.227, 2606:7100:1:69::3f, ... 正在连接 nginx.org (nginx.org)|206.251.255.63|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：981093 (958K) [application/octet-stream] 正在保存至: “nginx-1.12.1.tar.gz” 100%[=======================================================================================>] 981,093 40.8KB/s 用时 35s 2017-08-08 21:52:08 (27.3 KB/s) - 已保存 “nginx-1.12.1.tar.gz” [981093/981093]) [root@juispan src]# tar zxf nginx-1.12.1.tar.gz
2、配置与安装
[root@juispan src]# cd nginx-1.12.1 [root@juispan nginx-1.12.1]# ./configure --prefix=/usr/local/nginx [root@juispan nginx-1.12.1]# echo $? 0 [root@juispan nginx-1.12.1]# make && make install [root@juispan nginx-1.12.1]# echo $? 0
3、编辑启动文件
[root@juispan nginx-1.12.1]# vi /etc/init.d/nginx
#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start()
{
echo -n $"Starting $prog: "
mkdir -p /dev/shm/nginx_temp
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
echo
return $RETVAL
}
stop()
{
echo -n $"Stopping $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
echo
return $RETVAL
}
reload()
{
echo -n $"Reloading $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}
restart()
{
stop
start
}
configtest()
{
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $"Usage: $0 {start|stop|reload|restart|configtest}"
RETVAL=1
esac
exit $RETVAL4、授权与启动
[root@juispan nginx-1.12.1]# chmod 755 /etc/init.d/nginx [root@juispan nginx-1.12.1]# chkconfig --add nginx [root@juispan nginx-1.12.1]# chkconfig nginx on
5、编辑配置文件
[root@juispan nginx-1.12.1]# cd /usr/local/nginx/conf/; mv nginx.conf nginx.conf.bak
[root@juispan conf]# vi nginx.conf
user nobody nobody;
worker_processes 2;

}6、检查与启动
[root@juispan conf]# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [root@juispan conf]# /etc/init.d/nginx start Starting nginx (via systemctl): [ 确定 ] [root@juispan conf]# netstat -lntp |grep 80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 14196/nginx: master
7、测试php解析
[root@juispan conf]# vi /usr/local/nginx/html/1.php <?php echo "test"; ?> [root@juispan conf]# curl localhost/1.php test
