Nginx+Keepalived+@R_696_7949@ 源码

第一部分环境准备
一：Nginx+keepalived服务器两台（调度器，双机热备）
系统：Linux—CentOS7.4
IP地址：192.168.80.100（lvs01）
192.168.80.101（lvs02）
软件需求：Nginx安装包（Nginx-1.13.9.tar.gz）
Keepalived安装包（keepalived-1.4.2.tar.gz）
二：@R_696_7949@服务器两台（服务器池）
系统：Linux—CentOS7.4
IP地址：192.168.80.102（TM01）
192.168.80.103（TM02）
软件需求：java环境jdk包（jdk-8u144-linux-x64.tar.gz）
@R_696_7949@安装包（apache-@R_696_7949@-8.5.23.tar.gz）

192.168.80.100

1、源码安装Nginx

yum install -y \        //安装编译工具及插件
 gcc  gcc-c++  make  openssl-devel  zlib-devel \

useradd -s /sbin/nologin -M Nginx --创建一个不能登录服务器，并且没有家目录的用户

tar vxf Nginx-?.tar.gz ---解压Nginx软件包

cd Nginx-1.13.9 --切换到解压目录里

./configure \               //个性化配置
 --user=Nginx --group=Nginx --with-file-aio  --with-http_flv_module  --with-http_stub_status_module  --with-http_ssl_module  --with-http_gzip_static_module  --with-http_realip_module

@H_52_25@make && make install –编译且安装

//制作启动脚本
[[email?protected] conf.d]# vi /etc/init.d/Nginx
#!/bin/bash
#chkconfig: 35 99 20
#description: Nginx service Control Script

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

chmod +x /etc/init.d/Nginx        //增加执行权限
chkconfig --add Nginx             //加入系统管理服务
service Nginx start               //启动Nginx服务
netstat -anpt | grep 80

2、源码编译keepalived

yum -y install \         //安装插件
> popt-devel > kernel-devel > openssl-devel

tar xvf keepalived-1.4.2.tar.gz   --解压keepalived压缩包
 cd keepalived-1.4.2            --切换到解压目录
 ./configure --prefix=/           --配置
 make && make install        --编译与安装

cp keepalived/etc/init.d/keepalived /etc/init.d/

//以下编辑keepalived配置文件
cd /etc/keepalived/
vi keepalived.conf

! Configuration File for keepalived
global_defs {
        route_id Nginx-01
   }
vrrp_script Nginx {
        script "/opt/Nginx.sh"
        interval 2
        weight -10
}
vrrp_instance VI_1 {
    state MASTER
    interface ens32
    virtual_router_id 51
    priority 150
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    track_script {
        Nginx
        }
    virtual_ipaddress {
        192.168.80.100
    }
}
//注意，主备的优先级配置的相差50

创建脚本文件
判断keepalived进程是否存在，在就启动Nginx不在就关闭
vi /opt/Nginx.sh

#!/bin/bash 
#Filename:Nginx.sh
A=$(ps -ef | grep keepalived | grep -v grep | wc -l)
if [ $A -gt 0 ]; then
        /etc/init.d/Nginx start
else
        /etc/init.d/Nginx stop
fi

chmod +x /opt/Nginx.sh --给脚本文件加执行权限

service keepalived start --启动keepalived，会连Nginx一块启动

ip addr show dev ens32 --查看漂移地址是否生成

---------------测试验证------------
[[email?protected] keepalived]# systemctl stop keepalived    //关闭keepalived服务
[[email?protected] keepalived]# killall -9 Nginx              //关闭nignx服务
[[email?protected] keepalived]# netstat -anpt | grep 80       //80端口已停止运行

[[email?protected] keepalived]# systemctl start keepalived     //开启keepalived服务
[[email?protected] keepalived]# netstat -anpt | grep 80       //Nginx随keepalived启动

———————配置从服务器——————————–
1、源码编译安装Nginx
从服务器源码安装Nginx，和主服务器一样，根据主服务器操作在做一遍
需要修改的地方

2、源码安装keepalived
操作和主服务器相同,在写到Nginx.sh脚本文件时不同，其它的操作一模一样。

#!/bin/bash
#Filename:Nginx.sh
A=$(ip addr | grep 192.168.80.188/32 | grep -v grep | wc -l)
if [ $A -gt 0 ]; then
        /etc/init.d/Nginx start
else
        /etc/init.d/Nginx stop
fi

chmod +x /opt/Nginx.sh --给脚本执行权限

service keepalived start --启动 keepalived

二：模拟主服务故障

主服务器

killall 命令需要安装 : yum install psmisc -y
//80端口已不运行
[[email?protected] ~]# ip addr show dev ens32

//漂移地址消失，不工作

从服务器
[[email?protected] ~]# ip addr show dev ens32 //查看漂移地址

//漂移地址自动生成
[[email?protected] ~]# netstat -anpt | grep 80

主服务器

[[email?protected] ~]# service keepalived start
[[email?protected] ~]# ip addr show dev ens33

[[email?protected] ~]# netstat -anpt | grep 80

//主服务器已恢复工作

从服务器
[[email?protected] ~]# ip addr show dev ens33

//漂移地址自动移除
[[email?protected] ~]# netstat -anpt | grep 80

//Nginx自动停止服务
//双机热备验证成功

#  192.168.80.102

第三部分  部署服务器池—搭建@R_696_7949@
//以下在两台@R_696_7949@服务器上操作
第一步：部署第一个节点服务器TM01（192.168.80.102）
----------部署java环境，jdk---------

[[email?protected] ~]# tar xvf jdk-8u144-linux-x64.tar.gz //解压jdk
[[email?protected] ~]# cp -r jdk1.8.0_144/ /usr/local/java //创建java源目录
[[email?protected] ~]# vi /etc/profile
最后添加以下内容：
export JAVA_HOME=/usr/local/java
export JRE_HOME=/usr/local/java/jre
export PATH=$PATH:/usr/local/java/bin
export CLASSPATH=./:/usr/local/java/lib:/usr/local/java/jre/lib
保存退出
[[email?protected] ~]# source /etc/profile //立即生效
[[email?protected] ~]# java –version //查看版本

java环境部署完成

———-部署@R_696_7949@———-
[[email?protected] ~]# tar xvf apache-@R_696_7949@-8.5.23.tar.gz //解压apache-@R_696_7949@
[[email?protected] ~]# cp -r apache-@R_696_7949@-8.5.23 /usr/local/@R_696_7949@8 //创建@R_696_7949@源目录
//做个软链接，使@R_696_7949@开启与关闭更加方便
[[email?protected] ~]# ln -s /usr/local/@R_696_7949@8/bin/startup.sh /usr/bin/@R_696_7949@up
[[email?protected] ~]# ln -s /usr/local/@R_696_7949@8/bin/shutdown.sh /usr/bin/@R_696_7949@down
[[email?protected] ~]# @R_696_7949@up //开启@R_696_7949@

[[email?protected] ~]# netstat -anpt | grep 8080

-----------验证------------
 1. Win7下访问默认主页：http://192.168.80.102:8080
 ![](https://s1.51cto.com/images/blog/201901/11/09e2caf1242ACBb82147737b8b7dca10.png?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)
 //@R_696_7949@部署成功
 2. 服务器池中有两台@R_696_7949@服务器，为了便于识别，主页上添加点标记
 [[email?protected] ~]# vi /usr/local/@R_696_7949@8/webapps/ROOT/index.jsp
 添加一行内容：
 ![](https://s1.51cto.com/images/blog/201901/11/2e8898788728c2c24a27e827b56f5b85.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk=)
 保存退出
 [[email?protected] ~]# @R_696_7949@down
 [[email?protected] ~]# @R_696_7949@up       //重启
//再次访问默认主页http://192.168.80.102:8080
 ![](https://s1.51cto.com/images/blog/201901/11/502b68e27abeed12fd200763ccf04f65.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk=)

 192.168.80.103

提示:操作与192.168.80.102基本一样
需要修改的地方就是把 SERVER  AA  改成  SERVER BB j 就可以了

 --------测试------
 地址栏里输入:192.168.80.188:8080,点击刷新按钮查看是否动态轮询。
