keepalived编译安装

编译安装keepalived

使用源码先安装keepalived 1.2.6

cd/usr/local/src

wget http://www.keepalived.org/software/keepalived-1.2.6.tar.gz

tarzxf keepalived-1.2.6.tar.gz 

cdkeepalived-1.2.6

./configure--prefix=/usr/local/keepalived 

make

makeinstall

所设keepalived安装到/usr/local/keepalived,则所有配置文件均位于此目录之下。我一直没搞明白一个问题，Linux默认总是将程序安装到/usr/local目录下，所有程序共享了/usr/local/sbin目录。这对一些人的操作习惯是有影响的。为何不考虑使用每个软件一个独立的目录呢？

1. 建立服务启动脚本，以便使用service命令控制之
cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/keepalived

chmod+x /etc/init.d/keepalived

因为我们使用非默认路径（/usr/local）安装keepalived, 故需要修改几处路径，以保证keepalived能正常启动, 需要修改的文件如下：

2. 修改/etc/init.d/keepalived,寻找大约15行左右的./etc/sysconfig/keepalived, 修改为：
.  /usr/local/keepalived/etc/sysconfig/keepalived, 即指向正确的文件位置

同时在上述行下添加以下内容（将keepavlied主程序所在路径导入到环境变量PATH中）：

PATH="$PATH:/usr/local/keepalived/sbin"

exportPATH

3. 修改/usr/local/keepalived/etc/sysconfig/keepalived文件，设置正确的服务启动参数
KEEPALIVED_OPTIONS="-D -f/usr/local/keepalived/etc/keepalived/keepalived.conf"

4. 经过以上修改，keepalived基本安装即可完成，启动测试之：
service keepalived restart

5. 切勿忘记将此服务设置为开机启动

chkconfigkeepalived on
