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
