Ubuntu編譯安裝Keepalived

Keepalived是一種防止單點故障的高可用解決方案。

首先下載:

cd /usr

wget http://www.keepalived.org/software/keepalived-1.2.7.tar.gz

解壓：

tar zxvf keepalived-1.2.7.tar.gz

編譯之前需要安裝幾個程式庫

apt-get install libssl-devapt-get install opensslapt-get install libpopt-dev

然後運行

./configure --prefix=/usr

得到如下結果：

Keepalived configuration------------------------Keepalived version       : 1.2.7Compiler                 : gccCompiler flags           : -g -O2Extra Lib                : -lpopt -lssl -lcrypto Use IPVS Framework       : YesIPVS sync daemon support : YesIPVS use libnl           : NoUse VRRP Framework       : YesUse VRRP VMAC            : YesSNMP support             : NoUse Debug flags          : No

編譯吧：

make

make install

程式安裝到下面幾個目錄：

/usr/sbin中包含可執行程式keepalived

/usr/etc/keepalived/ 中包含了設定檔和例子

/usr/etc/rc.d/init.d/keepalived 是可以作為service的指令檔,複製到/etc/init.d目錄下

修改三處：

#. /etc/rc.d/init.d/functions. /lib/lsb/init-functions

#. /etc/sysconfig/keepalived. /usr/etc/sysconfig/keepalived

因為redhat之外的Linux沒有上面兩處目錄。

下面也要修改，將${..} 直接用start替換。

start() {    echo -n $"Starting $prog: "    #daemon keepalived ${KEEPALIVED_OPTIONS}    daemon keepalived start    RETVAL=$?    echo    [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog}

還要建立目錄

mkdir -p /var/lock/subsys

現在設定為系統服務

update-rc.d keepalived default

安裝daemon服務。

apt-get install daemon

好了，終於可以正常啟動了。

service keepalived start

關閉用

service keepalived stop
