安装JDK

cd /usr/local
tar -zxvf jdk-7u80-linux-x64.gz

配置环境变量
复制下列参数至/etc/profile结尾

vi /etc/profile
#set java environment
JAVA_HOME=/usr/local/jdk1.7.0_80
CLASSPATH=.:$JAVA_HOME/lib.tools.jar
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME CLASSPATH PATH

运行：source /etc/profile 使配置文件生效

安装Zookeeper

cd /usr/local
tar -zxvf zookeeper-3.4.6.tar
mv zookeeper-3.4.6 zookeeper-3.4.6-2181
mkdir -p /data/logs/zookeeper-2181/
mkdir -p /data/zookeeper-3.4.6-2181/data

修改环境变量

vi /usr/local/zookeeper-3.4.6-2181/bin/zkEnv.sh
#配置zookeeper日志打印zookeeper.out输出路径
ZOO_LOG_DIR="/data/logs/zookeeper-2181/"
#增加内存,在文件底部增加(生产可增加4096)
export JVMFLAGS="-Xms1024m -Xmx4096m $JVMFLAGS"

查询实例堆内存大小

ps -ef|grep zookeeper
#查询pid
jmap --heap  pid

单实例配置
vi /usr/local/zookeeper-3.4.6-2181/conf/zoo.cfg

#心跳时间
tickTime=5000
initLimit=10
syncLimit=5
maxClientCnxns=0
#数据保存目录
dataDir=/data/zookeeper-3.4.6-2181/data
#客户端连接端口
clientPort=2181
#快照副本数量，默认为3
autopurge.snapRetainCount=5
#定时1个小时清除快照与事务日务
autopurge.purgeInterval=1

集群配置
复制/usr/local/zookeeper-3.4.6到备用服务2、3(需保持奇数个节点)
在部署zookeeper节点的各服务器data目录下新建myid标识节点编号
#节点1
echo 1 > /data/zookeeper-3.4.6-2181/data/myid
#节点2
echo 2 > /data/zookeeper-3.4.6-2181/data/myid
#节点3
echo 3 > /data/zookeeper-3.4.6-2181/data/myid

#各节点添加server信息
vi /usr/local/zookeeper-3.4.6-2181/conf/zoo.cfg

#心跳时间
tickTime=5000
initLimit=10
syncLimit=5
maxClientCnxns=0
#数据保存目录
dataDir=/data/zookeeper-3.4.6-2181/data

#客户端连接端口
clientPort=2181
#快照副本数量，默认为3
autopurge.snapRetainCount=5
#定时1个小时清除快照与事务日务
autopurge.purgeInterval=1

#(server.1 : 1代表机器ID,对应上述节点标识myid)
server.1=x.x.x.x:2555:3555
server.2=x.x.x.x:2555:3555
server.3=x.x.x.x:2556:3556

服务启动与停止
/usr/local/zookeeper-3.4.6-2181/bin/zkServer.sh start
/usr/local/zookeeper-3.4.6-2181/bin/zkServer.sh stop
如果是集群多节点依次启动

验证启动状态
telnet 127.0.0.1 2181

安装Tomcat

unzip apache-tomcat-7.0.63.zip -d /usr/local/
cd /usr/local/
mv apache-tomcat-7.0.63 apache-tomcat-7.0.63-4000
cd apache-tomcat-7.0.63-4000
chmod -R +x *
mv webapps/ROOT webapps/ROOT.bak

容器内存配置:
vi bin/catalina.sh

Catalina.sh头部增加语句
JAVA_OPTS='-Xms1024m -Xmx4096m -XX:PermSize=256M -XX:MaxPermSize=256M'

#修改容器端口
vi /usr/local/apache-tomcat-7.0.63-4000/conf/server.xml

<Server port="4005" shutdown="SHUTDOWN">
<Connector port="4000" protocol="HTTP/1.1"
