keepalived安装步骤

一、安装与配置

1.1 下载及安装

以当前最新版本1.3.4为例

将从官网下载的keepalived-1.3.4.tar.gz包，上传到/tmp目录下。

 

 

tar -zxvfkeepalived-1.3.4.tar.gz

 

cd keepalived-1.3.4

 

./configure --prefix=安装路径

 

make && make install

 

 

 

1.2 配置

安装完成后，进入安装目录的etc目录下，将keepalived相应的配置文件拷贝到系统相应的目录当中。keepalived启动时会从/etc/keepalived目录下查找keepalived.conf配置文件，如果没有找到则使用默认的配置。/etc/keepalived目录安装时默认是没有安装的，需要手动创建。配置文件目录结构如下所示：

 

-- keepalived

|   |-- keepalived.conf

|   `-- samples

|       |-- keepalived.conf.status_code

|       |-- keepalived.conf.track_interface

|       |-- keepalived.conf.vrrp

|       |-- 。。。

|-- rc.d

|   `-- init.d

|       `-- keepalived

`-- sysconfig

    `-- keepalived

 

分别对应系统目录：

/etc/keepalived/keepalived.conf

/etc/rc.d/init.d/keepalived

/etc/sysconfig/keepalived

 

将配置文件拷贝到系统对应的目录下：

mkdir /etc/keepalived

cp /usr/local/keepalived/etc/keepalived.conf /etc/keepalived/keepalived.conf

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/keepalived

cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/keepalived

 

keepalived服务控制

systemctl enable keepalived.service #设置开机自动启动

systemctl disable keepalived.service     #取消开机自动启动

systemctl start keepalived.service       #启动服务

systemctl restart keepalived.service     #重启服务

systemctl stop keepalived.service         #停止服务

systemctl status keepalived.service      #查看服务状态

设置防火墙打开

firewall-cmd --permanent–-add-service=keepalived

firewall-cmd --reload

再次强调：Keepalived的所有功能是配置keepalived.conf文件来实现的。
