## 一、准备工作 ##

准备nginx-module-vts-master.zip、nginx-1.15.9.tar.gz源码包放到/opt目录下

## 二、系统初始化设置 ##

#!/bin/bash
    #################################关闭防火墙#######################################
    systemctl stop firewalld.service &> /dev/null
    if [ $? -eq 0 ];then 
      echo "防火墙已关闭"
    else
      echo "防火墙关闭失败,请重新操作"
      break
    fi  
    systemctl disable firewalld.service &> /dev/null
    if [ $? -eq 0 ];then
      echo "防火墙已设置为开机不启动"
    else
      echo "防火墙开机不启动设置失败，请重新开始"
      break
    fi
    ###################################关闭安全中心#####################################
    setenforce 0     ####
    echo "selinux已关闭" 
    sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config &> /dev/null
    grep -w "SELINUX=disabled" /etc/selinux/config &> /dev/null
    if [ $? -eq 0 ];then
      echo "selinux已设置为永久关闭"
    else
      echo "selinux设置永久关闭失败"
      break
    fi
    ################################检测调试网卡网络状态##################################
    ping -c1 -w1 -i0.2 www.baidu.com &> /dev/null
    if [ $? -eq 0 ];then
      echo "网络正常"
    else 
      sed -i 's/BOOTPROTO="dhcp"/BOOTPROTO="static"/' /etc/sysconfig/network-scripts/ifcfg-ens33
    read -p "请输入IP地址： " ip
    read -p "请输入子网掩码: " mask
    read -p "请输入网关地址: " way
    read -p "请输入DNS: " dns
    
    cat<<EOF>>/etc/sysconfig/network-scripts/ifcfg-ens33
    IPADDR=$ip
    NETMASK=$mask
    GATEWAY=$way
    DNS=$dns
    EOF
    
    systemctl restart network &>/dev/null
    ping -c2 www.baidu.com &> /dev/null
    if [ $? -eq 0 ];then
      echo "网络正常"
    else
      echo "网络设置失败"
    fi
    
    fi
    ################################# 修改主机名 ##########################################
    read -p "修改主机名：需要输入1；不需要输入2： " xuanze
    case $xuanze in 
    1)
    read -p "输入新的主机名： " xin
    hostnamectl set-hostname $xin
    su
    ;;
    2)
    echo "nice"
    ;;
    *)
    echo "输入错误！"
    esac

执行结果

防火墙已关闭
    防火墙已设置为开机不启动
    selinux已关闭
    selinux已设置为永久关闭
    网络正常
    修改主机名：需要输入1；不需要输入2： 1
    输入新的主机名： zwb

## 三、安装Nginx ##

### 1、安装依赖环境 ###

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

### 2、编译安装 ###

#### 2.1、解压安装包 ####

cd /opt                          ##进入压缩包位置
    tar -xzvf nginx-1.15.9.tar.gz    ##解压nginx-1.15.9压缩包
    
    unzip nginx-module-vts-master.zip      ## 解压压缩包
    mv nginx-module-vts-master /usr/local/  ##复制nginx-module-vts-master到/usr/local/

#### 2.2、安装组件 ####

cd /opt/nginx-1.15.9/
    ./configure \
    --prefix=/usr/local/nginx \
    --user=nginx \
    --group=nginx \
    --add-module=/usr/local/nginx-module-vts-master

#### 2.3、make && make install ####

make && make install
    
    ln -s /usr/local/nginx/sbin/* /usr/local/sbin/  ##建立软连接到/usr/local/sbin/方便执行
                                                    ##时不需要以绝对路径方式执行   
                                                 
    
    nginx -V           ### 查看安装的模块情况
    
    useradd -M -s /sbin/nologin nginx  ###添加用户
    
    nginx -t           ##检查配置文件语法是否有问题
    
    nginx              ##启动

###  ###

### 3、安装优化 ###

配置nginx.service文件，并赋予权限

[root@zwb nginx-1.15.9]# vim /usr/lib/systemd/system/nginx.service
    
    [Unit]	
    Description=nginx							
    After=network.target						
    [Service]
    Type=forking								
    PIDFile =/usr/local/nginx/logs/nginx.pid	
    ExecStart=/usr/local/nginx/sbin/nginx		
    ExecrReload=/bin/kill -s HUP $MAINPID		
    ExecrStop=/bin/kill -s QUIT $MAINPID		
    PrivateTmp=true
    [Install]
    WantedBy=multi-user.target
    
    
    
    
    chmod 754 /lib/systemd/system/nginx.service  ##赋予权限
    
    systemctl enable nginx --now  ##立即启动并设置为开机启动

![7e5f8177201642249f949045a27dcf5d.png][]

### 4、 修改/usr/local/nginx/conf/nginx.conf的配置文件 ###

vim /usr/local/nginx/conf/nginx.conf
    
    1、取消65~71行的注释符#号
    
     65         location ~ \.php$ {
     66             root           html;
     67             fastcgi_pass   127.0.0.1:9000;
     68             fastcgi_index  index.php;
     69             fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
     70             include        fastcgi_params;
    
    2、75 行增加index.php
    45             index  index.html index.htm index.php;
    
    
    3、第20行增加   
    vhost_traffic_status_zone;
    log_format main '{ "@timestamp": "$time_local", '
    '"@fields": { '
    '"uri":"$request_uri",'
    '"url":"$uri",'
    '"upstream_addr":"$upstream_addr",'
    '"remote_addr": "$remote_addr", '
    '"remote_user": "$remote_user", '
    '"body_bytes_sent": "$body_bytes_sent", '
    '"host":"$host",'
    '"server_addr":"$server_addr",'
    '"request_time": "$request_time", '
    '"request_time":"$request_time",'
    '"status":"$status",'
    '"request": "$request", '
    '"request_method": "$request_method", '
    '"size":$body_bytes_sent,'
    '"upstream_time":"$upstream_response_time"'
    '"http_referrer": "$http_referer", '
    '"body_bytes_sent":"$body_bytes_sent", '
    '"http_x_forwarded_for": "$http_x_forwarded_for", '
    '"http_user_agent": "$http_user_agent" } }';
    
    4、在
     location / {
                root   html;
                index  index.html index.htm;
     }    下增加内容
      location /status {
                vhost_traffic_status_display;
                vhost_traffic_status_display_format html;
    
    
    
    
    systemctl restart nginx.service   ###更改配置文件后需要重启服务

## 四、验证 ##

登录查看参数（这个IP是我虚拟机的ens33的地址）还请自行查看自己的ip地址。
