安装keepalived, 以及安装时遇见的问题

安装keepalived

1、下载keepalived安装包。官网地址

2、上传到linux相关目录,并且用tar -xvf 报名解压，解压后相关目录如下图：

3、在当前目录执行 ./configure命令

3.1如果出现类似错误，说明安装失败。

configure: error:
!!! OpenSSL is not properly installed on your system. !!!
!!! Can not include OpenSSL headers files. !!!

原因是：OpenSSL没有在当前系统中安装。
解决办法：yum install -y openssl openssl-devel
然后再次执行./configure命令

3.2如果出现下图提示说明安装成功。

4、执行make命令

5、执行make install（keepalived安装目录文件如下图）

6、启动keepalived

命令：/usr/local/etc/rc.d/init.d/keepalived start

6.1、如果报错如下，说明启动文件中的配置和系统不一致

/usr/local/etc/rc.d/init.d/keepalived: line 15: /etc/sysconfig/keepalived: No such file or directory

解决方式1：cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/

解决方式2：修改/usr/local/etc/rc.d/init.d/keepalived中的配置

# Source configuration file (we set KEEPALIVED_OPTIONS there)

#. /etc/sysconfig/keepalived(这行注释掉，换成下面的那行)

. /usr/local/etc/sysconfig/keepalived

6.2、启动报错：

Starting keepalived: /bin/bash: keepalived: command not found
解决方式：cp /usr/local/sbin/keepalived /usr/sbin/

有字样：Starting keepalived: [ OK ]表示启动成功
