keepalived編譯安裝

編譯安裝keepalived

使用源碼先安裝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

所設keepalived安裝到/usr/local/keepalived,則所有配置文件均位于此目錄之下。我一直沒搞明白一個問題，Linux默認總是將程序安裝到/usr/local目錄下，所有程序共享了/usr/local/sbin目錄。這對一些人的操作習慣是有影響的。為何不考慮使用每個軟件一個獨立的目錄呢？

1. 建立服務啟動腳本，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

因為我們使用非默認路徑（/usr/local）安裝keepalived, 故需要修改幾處路徑，以保證keepalived能正常啟動, 需要修改的文件如下：

2. 修改/etc/init.d/keepalived,尋找大約15行左右的./etc/sysconfig/keepalived, 修改為：
.  /usr/local/keepalived/etc/sysconfig/keepalived, 即指向正確的文件位置

同時在上述行下添加以下內容（將keepavlied主程序所在路徑導入到環境變量PATH中）：

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

exportPATH

3. 修改/usr/local/keepalived/etc/sysconfig/keepalived文件，設置正確的服務啟動參數
KEEPALIVED_OPTIONS="-D -f/usr/local/keepalived/etc/keepalived/keepalived.conf"

4. 經過以上修改，keepalived基本安裝即可完成，啟動測試之：
service keepalived restart

5. 切勿忘記將此服務設置為開機啟動

chkconfigkeepalived on
