Alibaba Cloud Linux 3.2104 64位安装nginx-1.16.1

本文主要是介绍Alibaba Cloud Linux 3.2104 64位安装nginx-1.16.1，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

　　　　1   下载nginx

                           从nginx官网 http://nginx.org/ 下载新的稳定版本nginx 并上传到linux服务器

               2  安装nginx 所需要的扩展     

            yum -y install pcre openssl  openssl-devel

                3  安装nginx

                useradd -s /sbin/nologin www 
                tar zxvf nginx-1.8.0.tar.gz 
                cd nginx-1.8.0
                ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --without-http-cache --with-http_ssl_module  --with-pcre=/home/www/pcre-8.31 (源文件的解压路径不是安装路径)                --with-http_gzip_static_module
                make 
                make install

                          配置nginx开机启动文件

                          vi  /etc/init.d/nginx 写入如下内容 根据实际情况修改

#!/bin/sh
#
# nginx - this script start and stop the nginx daemon
#
# chkconfig: 2345 55 25
# description: Startup script for nginx
# processname: nginx
# config: /usr/local/nginx/conf/nginx.conf
# pidfile: /var/run/nginx.pid
#
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
                                                   
DAEMON=/usr/local/nginx/sbin/nginx
CONFIGFILE=/usr/local/nginx/conf/nginx.conf
PIDFILE=/var/run/nginx.pid
SCRIPTNAME=/etc/init.d/nginx
LOCKFILE=/var/lock/nginx.lock
                                                   
set -e
[[ -x "$DAEMON" ]] || exit 0
                                                   
start() {
    echo "Startting Nginx......"
    [[ -x $DAEMON ]] || exit 5
    [[ -f $CONFIGFILE ]] || exit 6
    $DAEMON -c $CONFIGFILE || echo -n "Nginx already running!"
    [[ $? -eq 0 ]] && touch $LOCKFILE
}
                                                   
stop() {
    echo "Stopping Nginx......"
    MPID=`ps aux | grep nginx | awk '/master/{print $2}'`
                                                      
    if [[ "${MPID}X" != "X" ]]; then
        kill -QUIT $MPID
        [[ $? -eq 0 ]] && rm -f $LOCKFILE
    else
        echo "Nginx server is not running!"
    fi
}
                                                   
reload() {
    echo "Reloading Nginx......"
    MPID=`ps aux | grep nginx | awk '/master/{print $2}'`
                                                      
    if [[ "${MPID}X" != "X" ]]; then
        kill -HUP $MPID
    else
        echo "Nginx can't reload!"
    fi
}
                                                   
case "$1" in
start)
    start
    ;;
                                                      
stop)
    stop
    ;;
                                                      
reload)
    reload
    ;;
                                                      
restart)
    stop
    sleep 1
    start
    ;;
                                                      
*)
    echo "Usage: $SCRIPTNAME {start|stop|reload|restart}"
    exit 3
    ;;
esac
                                                   
exit 0

                4 设置开机启动

              chmod 755 /etc/init.d/nginx
              chkconfig --add nginx
              chkconfig  nginx on
              /etc/init.d/nginx start  

                5 测试

                     用浏览器访问实际的域名 看看是否正常

                     重启服务器 看nginx 是否随机启动

                6 配置相关

######## 查看nginx状态配置
location =/nginx_status {
        stub_status on;
        access_log off;
        #allow 127.0.0.1;
        #deny all;
 }

active connections – 活跃的连接数量
server accepts handled requests — 总共处理了11989个连接 , 成功创建11989次握手, 总共处理了11991个请求
reading — 读取客户端的连接数.
writing — 响应数据到客户端的数量
waiting — 开启 keep-alive 的情况下,这个值等于 active – (reading+writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接.
