一、基础环境

系统版本 nginx版本 keepalived版本 ip 作用
CentOS Linux release 7.5.1804 (Core) nginx/1.16.1 keepalived-2.0.18 10.1.1.31 master
CentOS Linux release 7.5.1804 (Core) nginx/1.16.1 keepalived-2.0.18 10.1.1.32 slave

VIP 10.1.1.111

二、安裝nginx

  1. 安裝nignx

    yum install nginx -y
  2. 修改nginx配置文件

    • master

      echo 'this is master 31' > /usr/share/nginx/html/index.html
    • slave

      echo 'this is slave 32' >  /usr/share/nginx/html/index.html 
  3. 启动nginx

    systemctl start nginx 
  4. 测试nginx启动

    curl localhost
    
    this is master

三、安装keepalived

1、 创建依赖环境

yum -y install openssl-devel gcc gcc-c++
mkdir /etc/keepalived
wget https://www.keepalived.org/software/keepalived-2.0.18.tar.gz

2、安装keepalived

tar -zxvf keepalived-2.0.18.tar.gz
mv keepalived-2.0.18 /usr/local/keepalived
cd /usr/local/keepalived
./configure && make && make install

3、创建启动文件

cp  -a /usr/local/etc/keepalived   /etc/init.d/
cp  -a /usr/local/etc/sysconfig/keepalived    /etc/sysconfig/
cp  -a /usr/local/sbin/keepalived    /usr/sbin/

4、创建配置文件

  1. master

    cat > /etc/keepalived/keepalived.conf << EOF
    ! Configuration File for keepalived
    global_defs {
           router_id 31
    } 
    vrrp_instance VI_1 {
           state MASTER
           interface ens33
           virtual_router_id 3
           mcast_src_ip 10.1.1.132
           priority 200
           advert_int 1 
           authentication {
                   auth_type PASS
                   auth_pass 123456
           }
           virtual_ipaddress {
                   10.1.1.111/24
           }
    }
    EOF
  2. slave

    cat > /etc/keepalived/keepalived.conf << EOF
    ! Configuration File for keepalived
    global_defs {
           router_id 32
    } 
    vrrp_instance VI_1 {
           state BACKUP
           interface ens33
           virtual_router_id 3
           mcast_src_ip 10.1.1.132
           priority 90 
           advert_int 1 
           authentication {
                   auth_type PASS
                   auth_pass 123456
           }
           virtual_ipaddress {
                   10.1.1.111/24
           }
    }
    EOF

5、启动keepalived

systemctl start keepalived
systemctl enable keepalived

四、测试

1、在两台服务器上测试

  1. master

    $ curl localhost
    this is master
    root@centos7[14:46:07]:~
    $ curl 10.1.1.111
    this is master
    root@centos7[15:03:29]:~
  2. slave

    $ curl localhost
    this is slave
    root@centos7[15:03:59]:/etc/keepalived
    $ curl 10.1.1.111
    this is master

2、关闭master的keepalived模仿down机

  1. master关闭keepalived

    $ systemctl stop keepalived 
  2. 在slave上面进行测试
$  curl localhost
this is slave
root@centos7[15:10:29]:/etc/keepalived
$ curl 10.1.1.111
this is slave

到此keepalived完成
