linux zookeeper 自启动服务

舒畅

　　项目中用到zookeeper，运维部门要重启机器，要项目组的人现场维护，哥表示懒得到现场，直接将zookeeper做成服务。
　　首先配置你的zookeeper.
　　下载，解压( 我的放在/usr/zookeeper下)，配置zoo.cfg
　　zoo.cfg配置如下：
　　# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
dataDir=/usr/zookeeper
# the port at which the clients will connect
clientPort=2181

　　在/usr/zookeeper下创建目录logs,mkdir /usr/zookeeper/logs
　　
　　cp /usr/zookeeper/zookeeper-3.3.6/bin/zkServer.sh /etc/rc.d/init.d/zookeeper
　　cp /usr/zookeeper/zookeeper-3.3.6/bin/zkEnv.sh /etc/rc.d/init.d/zkEnv
　　
　　编辑/etc/rc.d/init.d/zookeeper，修改如下：
　　#1.注释掉
　　# Only follow symlinks if readlink supports it
#if readlink -f "$0" > /dev/null 2>&1
#then
#  ZOOBIN=`readlink -f "$0"`
#else
#  ZOOBIN="$0"
#fi
　　
　　#2.ZOOBINLINK指向/etc/rc.d/init.d/zookeeper
　　ZOOBINLINK=/etc/rc.d/init.d/zookeeper
　　#3.指向/usr/zookeeper/zookeeper-3.3.6/bin
　　ZOOBIN=/usr/zookeeper/zookeeper-3.3.6/bin
ZOOBINDIR=$ZOOBIN
　　#去掉后缀sh
. "$ZOOENVDIR"/zkEnv
　　
　　修改/etc/rc.d/init.d/zkEnv
　　if [ "x$ZOOCFGDIR" = "x" ]
then
    if [ -d "/etc/zookeeper" ]
    then
        ZOOCFGDIR="/etc/zookeeper"
    else
        #ZOOCFGDIR="$ZOOBINDIR/../conf"
        ZOOCFGDIR="$ZOOBIN/../conf"
    fi
fi

　　
if [ "x${ZOO_LOG_DIR}" = "x" ]
then
    #ZOO_LOG_DIR="."
     ZOO_LOG_DIR="$ZOOBIN/../logs"
fi

　　
　　配置启动级别
　　ln -s /etc/init.d/zookeeper /etc/rc3.d/K30zookeeper
　　ln -s /etc/init.d/zookeeper /etc/rc3.d/S70zookeeper
　　ln -s /etc/init.d/zookeeper /etc/rc5.d/K30zookeeper
　　ln -s /etc/init.d/zookeeper /etc/rc5.d/S70zookeeper
　　
　　为所有用户添加执行权限
　　chmod -f 777 /etc/init.d/zookeeper
chmod -f 777 /etc/rc3.d/S70zookeeper

　　验证：
　　service zookeeper start
　　service zookeeper stop
　　service zookeeper status
