Keepalived基础操作（安装配置）

从源代码编译时一般建议指定PREFIX。例如(不要执行下面的命令):

./configure --prefix&＃61;/usr/local/keepalived-2.1.5


这样&＃xff0c;只需删除父目录即可轻松卸载Keepalived的编译版本。此外&＃xff0c;这种安装方法允许安装多个版本的Keepalived&＃xff0c;而不会互相覆盖。使用符号链接指向所需的版本。

例如&＃xff0c;您的目录结构可能如下所示:

[root&＃64;lvs1 ~]# cd /usr/local
[root&＃64;lvs1 local]# ls -l
total 12
lrwxrwxrwx. 1 root root 17 Feb 24 20:23 keepalived -> keepalived-2.1.5
drwxr-xr-x 2 root root 4096 9月 13 09:38 keepalived-1.4.5
drwxr-xr-x 2 root root 4096 9月 13 09:38 keepalived-2.0.0
drwxr-xr-x 2 root root 4096 9月 13 09:39 keepalived-2.1.0
drwxr-xr-x 6 root root 4096 9月 12 08:13 keepalived-2.1.5

正确的配置参数

./configure --prefix&＃61;/usr/local/keepalived-2.1.5 \
--with-run-dir&＃61;/var/run/ \
--with-default-config-file&＃61;/etc/keepalived/keepalived.conf \
--enable-dynamic-linking \
--enable-regex --enable-regex-timers \
--enable-sha1 --enable-bfd \
--enable-snmp --enable-snmp-rfc \
--enable-snmp-checker --enable-snmp-vrrp \
--enable-snmp-keepalived

部分配置参数说明

2.4 编译

编译就是按照之前配置好的相关参数&＃xff0c;生成相关文件&＃xff0c;比如命令文件&＃xff0c;配置文件&＃xff0c;依赖库文件等。

make


2.5 安装

安装就是把编译好的相关文件&＃xff0c;按照之前配置好的参数拷贝到当前系统的指定目录中

make install

三、安装后的配置

1. 处理配置文件

首先从安装目录中拷贝配置文件到 /etc/keepalived 目录下

[root&＃64;shark etc]# cd /usr/local/keepalived-2.1.5/etc
[root&＃64;shark etc]# cp keepalived/keepalived.conf /etc/keepalived/


修改配置文件 /etc/keepalived/keepalived.conf 的如下内容

保证执行了上面的步骤。

[root&＃64;shark ~]# systemctl start keepalived # 启动
[root&＃64;shark ~]# systemctl status keepalived # 查看状态
[root&＃64;shark ~]# systemctl enable keepalived # 授权开启自动启动此服务
[root&＃64;shark ~]# systemctl stop keepalived # 停止
[root&＃64;shark ~]# systemctl restart keepalived # 重启
