Nginx虚拟主机以及自动启动脚本详解

想要部署Nginx虚拟主机，那么首先需要nginx的环境，那么我们一起来看一下吧
systemctl stop firewalld
iptables -F
setenforce 0
1)安装支持软件
yum -y install pcre-devel zlib-devel openssl-devel
2）创建运行用户，组
useradd -M -s /sbin/nologin nginx
3)编译安装nglinx
tar xf nglix-1.14.2.tar.gz -C /usr/src
4)配置编译
cd /usr/src/nginx-1.14.2
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module && make && make install
为了使nginx服务器运行方便，可以为主程序nginx 创建链接文件，以便管理员直接执行nginx命令
ln -s /usr/local/nginx/sbin/nginx /usr/local/bin
ll /usr/local/bin/nginx
5）nginx运行控制
nginx -t 检测语法
6)启动，停止nginx,如果服务器中已安装有httpd等其他web 服务软件，应关闭避免冲突
netstat -anpt |grep :80
nginx
netstat -anpt |grep :80
查看httpd:192.168.30.22窗口
welocome to nginx!
                               
killall -s HUP nginx  重载配置
killall -s QULT nginx     退出进程
killall -9
netstat -anpt |grep :80

为了更好管理nginx进程写个脚本并使用chkconfig工具来进行管理
vim /etc/init.d/nginx
#!/bin/bash
#chkconfig:2345 99 20

PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"

case "$1" in
start)
        $PROG
;;
stop)
        kill -s QUIT $(cat $PIDF)
;;
restart)
        $0 stop
        $0 start
;;
reload)
        kill -s HUP $(cat $PIDF)
;;
*)
        echo "Usage:$0{start|stop|restart|reload}"
        exit 1
esac
exit 0


netstat -anpt |grep :80     

给上权限
chmod +x /etc/init.d/nginx
chkconfig --add nginx
chkconfig nginx on
chkconfig --list nginx
然后测试脚本
/etc/init.d/nginx stop
netstat -anpt |grep :80
/etc/init.d/nginx start
netstat -anpt |grep :80

我这里并做了一个小的配置，查看/status下可以看到用户的访问量
在http{}配置的server{} 子配置文件内添加如下配置项
vim /usr/local/nginx/conf/nginx.conf
    location /status {
        stub_status on；
        access_log off;
    }
systemctl restart nginx
浏览器访问http://192.168.30.22/status


虚拟主机应用
mkdir /usr/local/nginx/html/zc
mkdir /usr/local/nginx/html/cloud
echo "<h1>www.zc.com</h1>"> /usr/local/nginx/html/zc/index.html
echo "<h1>www.cloud.com</h1>" > /usr/local/nginx/html/cloud/index.html
vim /usr/local/nginx/conf/nginx.conf

}

      
systemctl restart nginx
vim /etc/hosts

虚拟主机访问测试   elinks 命令需要yum -y install elinks安装
elinks --dump http://www.zc.com
elinks --dump http://www.cloud.com：81
