bash 脚本编程十八 Keepalived自动部署

紧接前面手工部署Keepalived的文章，这次来自动部署。

建立keepalived目录，里面已经存放了下载并解压的keepalived-1.2.7目录，包括和用于作为系统服务的keepalived脚本

注意，是前面一文修改过后能用于ubuntu的版本。

install.sh脚本内容：

#!/bin/bash 

source ../common/tool.sh

libssl="libssl-dev"
openssl="openssl"
popt="libpopt-dev"
daemonService="daemon"

installDpkg $libssl
installDpkg $openssl
installDpkg $popt
installDpkg $daemonService

cd keepalived-1.2.7
./configure --prefix=/usr
make
make install

cd ..

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 default

createFolder "/var/lock/subsys"
cd -
make clean

service keepalived start

里面使用了一个新的函数installDpkg，定义在tool.sh脚本中：

#$1 dpkg name
function installDpkg {
    hasDpkg $1
    r=$?
    
    if [ $r -eq 1 ]
    then
	echo "$1 was installed"
    else
	echo "$1 was not installed, installing..."
	apt-get install $1
    fi
}

keepalived的目录结构如下：

keepalived# tree -L 2
