一、基础环境
系统版本 nginx版本 keepalive版本 知识产权 作用 Linux CentOS释放7.5.1804(核心) nginx/1.16.1 keepalived-2.0.18 10.1.1.31 主 Linux CentOS释放7.5.1804(核心) nginx/1.16.1 keepalived-2.0.18 10.1.1.32 奴隶 VIP 10.1.1.111
二、安裝nginx
-
<李>
安裝nignx
<代码类=" language-bash "> yum安装nginx - y李 <李>
修改nginx配置文件
-
<李>
大师
<代码类=" language-bash ">回声“这是主31”比;/usr/share/nginx/html/index.html李 <李> 奴隶
<代码类=" language-bash ">回声32这是奴隶的祝辞/usr/share/nginx/html/index. 之前 李 李 <李>启动nginx
<代码类=" language-bash "> systemctl开始nginx李 <李>测试nginx启动
<代码类=" language-bash ">旋度localhost 这是大师李
三、安装keepalive
1,创建依赖环境
<代码类=" language-bash "> yum - y安装openssl-devel gcc gcc-c + + mkdir/etc/keepalived wget https://www.keepalived.org/software/keepalived-2.0.18.tar.gz
2,安装keepalive
<代码类=" language-bash ">焦油-zxvf keepalived-2.0.18.tar.gz mv keepalived-2.0.18/usr/local/keepalived cd/usr/local/keepalived ./configure,,使,,使安装
3,创建启动文件
<代码类=" language-bash "> 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
-
<李>
大师
<代码类=" language-bash ">猫比;/etc/keepalived/keepalived。参看& lt; & lt;EOF
!配置文件keepalive
global_defs {
router_id 31
}
vrrp_instance VI_1 {
国家的主人
接口ens33
virtual_router_id 3
mcast_src_ip 10.1.1.132
优先级200
advert_int 1
身份验证{
auth_type通过
auth_pass 123456
}
virtual_ipaddress {
10.1.1.111/24
}
}
EOF
李
<李>
奴隶
<代码类=" language-bash ">猫比;/etc/keepalived/keepalived。参看& lt; & lt;EOF
!配置文件keepalive
global_defs {
router_id 32
}
vrrp_instance VI_1 {
状态备份
接口ens33
virtual_router_id 3
mcast_src_ip 10.1.1.132
优先级90
advert_int 1
身份验证{
auth_type通过
auth_pass 123456
}
virtual_ipaddress {
10.1.1.111/24
}
}
EOF
李
5,启动keepalive
<代码类=" language-bash "> systemctl keepalive开始 systemctl启用keepalive
四、测试
1,在两台服务器上测试
-
<李>
大师
<代码类=" language-bash ">美元旋度localhost 这是主 root@centos7 [14:46:07]: ~ curl 10.1.1.111美元 这是主 root@centos7[15:03:29]: ~李 <李> 奴隶
<代码类=" language-bsh ">美元旋度localhost 这是奴隶 root@centos7 [15:03:59]:/etc/keepalive curl 10.1.1.111美元 这是大师李
2,关闭大师的keepalive模仿了机
-
<李>
主关闭keepalive
<代码类=" language-bash "> systemctl美元停止keepalive李 <李>在奴隶上面进行测试李
<代码类=" language-bash ">美元旋度localhost 这是奴隶 root@centos7 [15:10:29]:/etc/keepalive curl 10.1.1.111美元 这是奴隶
到此keepalive完成
