一、yum安装相关依赖

1. gcc 安装
安装 nginx 需要先将官网下载的源码进行编译，编译依赖 gcc 环境，如果没有 gcc 环境，则需要安装：

yum install gcc-c++

2. OpenSSL 安装

yum install -y openssl openssl-devel

二、解压编译安装

下载keepalived：https://www.keepalived.org/download.html

解压，编译

# 解压
tar -xzvf keepalived-2.0.16.tar.gz

cd keepalived-2.0.16
 
# 执行配置，指定路径
./configure --prefix=/usr/local/keepalived
# 编译
make && make install

拷贝相关文件到指定目录

# 拷贝源码中的keepalived-2.0.20/keepalived/etc/init.d/keepalived 到 /etc/init.d/
cp /usr/local/keepalived-2.0.20/keepalived/etc/init.d/keepalived /etc/init.d/

# 拷贝编译后的keepalived/etc/sysconfig/keepalived 到 /etc/sysconfig/
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

# 创建文件夹
mkdir /etc/keepalived

# 把配置文件移到文件夹中
cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/

# 把执行文件移动到/usr/sbin/
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

三、修改配置文件

节点1

! Configuration File for keepalived

global_defs {
    router_id node1 #标识
}

vrrp_instance VI_1 {
    state BACKUP           #角色是backup
    interface eth0         #当前使用的网卡
    virtual_router_id 51   #让master 和backup在同一个虚拟路由里，id 号必须相同
    priority 90            #优先级,因为我这里两个都是backup，不希望故障节点恢复后重新获取vip，优先级设置成一样
    advert_int 1           #心跳间隔时间
    authentication {
        auth_type PASS     #认证
        auth_pass shucai   #密码
    }
    virtual_ipaddress {
        172.16.70.126      #虚拟ip
    }
}

节点2

! Configuration File for keepalived

global_defs {
    router_id node2 #标识
}

vrrp_instance VI_1 {
    state BACKUP           #角色是backup
    interface eth0         #当前使用的网卡
    virtual_router_id 51   #让master 和backup在同一个虚拟路由里，id 号必须相同
    priority 90            #优先级,因为我这里两个都是backup，不希望故障节点恢复后重新获取vip，优先级设置成一样
    advert_int 1           #心跳间隔时间
    authentication {
        auth_type PASS     #认证
        auth_pass shucai   #密码
    }
    virtual_ipaddress {
        172.16.70.126      #虚拟ip
    }
}

四、启动服务

systemctl start keepalived


systemctl enable keepalived

五、测试ip漂移

关闭其中一个节点的服务器测试ip漂移

ip a | grep 172.16.70.126

inet 172.16.70.126/32 scope global eth0
