一、安装步骤：

1.下载系统对应的版本

wget

2.安装环境的准备

yum install gcc-c++ yum install pcre pcre-devel yum install zlib zlib-devel yum install openssl openssl-devel

3.检查是否安装了Nginx

find -name nginx yum remove nginx

4.解压

tar -zxvf nginx-1.12.0.tar.gz

5. 编译和安装

cd nginx-1.12.0 ./configure make make install

6. 查看版本

/usr/local/nginx/sbin/nginx -V

7. 启动重启

/usr/local/nginx/sbin/nginx //启动 /usr/local/nginx/sbin/nginx -s reload //重启 netstat -nltp | grep 80 //查看监听端口

8. 访问Nginx服务器

http://localhost

9. 停止

/usr/local/nginx/sbin/nginx -s stop //快速停止 /usr/local/nginx/sbin/nginx -s quit //完整停止 ps -ef | grep nginx //查看所有进程的全面进程 kill -quit 主进程号 //停止进程 kill -term 主进程号 //快速停止 kill -9 nginx //强制停止

10. 添加防火墙例外

//将80端口添加为防火墙例外 vim /etc/sysconfig/iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT //新增到文件中 /etc/init.d/iptables restart//重启防火墙

二、Nginx配置

1.编写shell脚本

# 添加修改此文件：vi /etc/init.d/nginx #!/bin/bash # nginx Startup script for the Nginx HTTP Server # it is v.0.0.2 version. # chkconfig: - 85 15 # description: Nginx is a high-performance web and proxy server. # It has a lot of features, but it\'s not for everyone. # processname: nginx # pidfile: /var/run/nginx.pid # config: /usr/local/nginx/conf/nginx.conf # 注意下面的两行要修改成你的实际路径 nginxd=/usr/local/nginx/sbin/nginx nginx_config=/usr/local/nginx/conf/nginx.conf nginx_pid=/var/run/nginx.pid RETVAL=0 prog="nginx" # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ ${NETWORKING} = "no" ] && exit 0 [ -x $nginxd ] || exit 0 # Start nginx daemons functions. start() { if [ -e $nginx_pid ];then echo "nginx already running...." exit 1 fi echo -n $"Starting $prog: " daemon $nginxd -c ${nginx_config} RETVAL=$? echo [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx return $RETVAL } # Stop nginx daemons functions. stop() { echo -n $"Stopping $prog: " killproc $nginxd RETVAL=$? echo [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid } # reload nginx service functions. reload() { echo -n $"Reloading $prog: " #kill -HUP `cat ${nginx_pid}` killproc $nginxd -HUP RETVAL=$? echo } # See how we were called. case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) stop start ;; status) status $prog RETVAL=$? ;; *) echo $"Usage: $prog {start|stop|restart|reload|status|help}" exit 1 esac exit $RETVAL

2. 设置文件的访问权限

chmod a+x /etc/init.d/nginx

3. 加入到rc.local文件中

# 修改vi /etc/rc.local，添加如下内容 /etc/init.d/nginx start

4. 设置开机启动

chkconfig --add nginx #添加系统服务 chkconfig --level 345 nginx on #设置开机启动,启动级别 chkconfig --list nginx #查看开机启动配置信息

三、 通过端口区分不同的虚拟主机

1. 修改nginx的配置文件，添加如下内容

# 在配置文件中添加server节点：写入多份server节点，其端口号不同来区分虚拟主机 server { listen 80; server_name localhost; location / { root html; index index.html index.htm; } } server { listen 81; server_name localhost; location / { root html81; index index.html index.htm; } }

2. 重启服务

/usr/local /nginx/sbin/nginx -s reload

四、 通过域名区分不同的虚拟主机

1. 本地windows电脑，修改 C:WindowsSystem32driversetchosts文件

192.168.31.117 manager.dhc.com 192.168.31.117 portal.dhc.com

2. 服务器Centos7中，修改/usr/local/nginx/conf/nginx.conf文件（在对应路径下添加mm和pp目录即可）

server { listen 80; server_name manager.dhc.com; location / { root mm; index index.html index.htm; } } server { listen 80; server_name portal.dhc.com; location / { root pp; index index.html index.htm; } }

3. 重启服务加载配置文件

/usr/local /nginx/sbin/nginx -s reload
