bash 指令碼編程十八 Keepalived自動部署

緊接前面手工部署Keepalived的文章，這次來自動部署。

建立keepalived目錄，裡面已經存放了下載並解壓的keepalived-1.2.7目錄，包括和用於作為系統服務的keepalived指令碼

注意，是前面一文修改過後能用於ubuntu的版本。

install.sh指令碼內容：

#!/bin/bash source ../common/tool.shlibssl="libssl-dev"openssl="openssl"popt="libpopt-dev"daemonService="daemon"installDpkg $libsslinstallDpkg $opensslinstallDpkg $poptinstallDpkg $daemonServicecd keepalived-1.2.7./configure --prefix=/usrmakemake installcd ..cp ./keepalived /etc/init.d/cd /etc/init.d/update-rc.d keepalived start 21 2 3 4 5 . stop 21 0 1 6 .#update-rc.d keepalived defaultcreateFolder "/var/lock/subsys"cd -make cleanservice keepalived start

裡面使用了一個新的函數installDpkg，定義在tool.sh指令碼中：

#$1 dpkg namefunction installDpkg {    hasDpkg $1    r=$?        if [ $r -eq 1 ]    thenecho "$1 was installed"    elseecho "$1 was not installed, installing..."apt-get install $1    fi}

keepalived的目錄結構如下：
