Linux installation and Configuration zookeeper 3.4.11

The following is an outline of the article:

1.zookeeper Foundation Environment.

2.zookeeper Basic Configuration installation.

3.zookeeper Simple Operation command.

On the introduction of zookeeper, I recommend (https://www.cnblogs.com/wuxl360/p/5817471.html) This article has been introduced very clearly

This article system and use version Description:

1.CentOS 7 Virtual machine system.

2. JDK 1.8.x version. (jdk-8u144-linux-x64.tar.gz)

3.zookeeper 3.4.10 (zookeeper-3.4.10.tar.gz)

1.1 Installation jdk1.8.x

Because zookeeper relies on the installation of JDK, a jdk1.8 installation is required first.

1.1.1 Now create a new directory in the Linux environment, software

[Root@localhost/]# mkdir Software

1.1.2 Then go to the official website of Oracle Download jdk-8u144-linux-x64.tar.gz This package, specific everyone to download it. Put the downloaded package in the software directory.

[Root@localhost/]# cp/software/jdk-8u144-linux-x64.tar.gz/usr/local/

Eventually install jdk1.8 yourself, and then configure environment variables.

#vi/etc/profile

Add the following inside

Export java_home=/usr/local/jdk1.8.0

Export Java_bin=/usr/local/jdk1.8.0/bin

Export path= $PATH: $JAVA _home/bin

Exportclasspath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar

Export Java_home java_bin PATH CLASSPATH

Let the/etc/profile file become effective immediately after modification, you can use the following command:

# . /etc/profile

Attention:. and/etc/profile have spaces.

Test the version of the JDK.

Java-version

2. Install Zookeeper

2.1 Download Address:

[Root@localhost/]# wget http://mirrors.shu.edu.cn/apache/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz

After the download is complete, also migrate to/usr/local/this directory, and then the MV renamed to Zookeeper.tar.gz, the following is the specific procedure

1. Create/usr/local/zookeeper folder:
Mkdir-p/usr/local/zookeeper

2, into the/usr/local/zookeeper directory:
Cd/usr/local/zookeeper

3, download zookeeper-3.4.11.tar.gz:
wget http://mirrors.shu.edu.cn/apache/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz

4, Decompression zookeeper-3.4.11.tar.gz:
TAR-ZXVF zookeeper-3.4.11.tar.gz

5, into the/usr/local/zookeeper/conf directory:
CD zookeeper/conf/

6, copy the Zoo_sample.cfg file and named for Zoo.cfg:
CP Zoo_sample.cfg Zoo.cfg

7, with vim open zoo.cfg file and modify its contents as follows:
# The number of milliseconds of each tick

# Zookeeper defined base time interval, in units: milliseconds
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.
# Don't use/tmp for storage,/tmp here is just
# example Sakes.
# Datadir=/tmp/zookeeper

# Data folder
Datadir=/usr/local/zookeeper/data

# Log folder (this version may not have this directory)
Datalogdir=/usr/local/zookeeper/logs

# The port at which the clients'll connect
# Client access to zookeeper port number
clientport=2181

# The maximum number of the client connections.
# Increase this if your need to handle more clients
#maxClientCnxns =60
#
# being sure to read the maintenance section of the
# Administrator Guide before turning on Autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in DataDir
#autopurge. snapretaincount=3
# Purge task interval in hours
# Set to ' 0 ' to disable Auto Purge feature
#autopurge. purgeinterval=1

8. Save and close Zoo.cfg file:

9, into the/usr/local/zookeeper/bin directory:
Cd.. /bin/

10, with vim open the/etc/directory profiles profile:
Vim/etc/profile
and append the following to its tail:

#zookeeper Config

Export zookeeper_home=/usr/local/zookeeper/
Export path= $ZOOKEEPER _home/bin: $PATH
Export PATH

11, so that the/etc/directory under the profile can be effective:
Source/etc/profile

12, Start zookeeper service:
zkserver.sh start
Printing the following information indicates successful startup:
Zookeeper JMX enabled by default
Using config:/usr/local/zookeeper/bin/. /conf/zoo.cfg
Starting zookeeper ... Started

13, Query Zookeeper status:
zkserver.sh status

14, close the Zookeeper service:
zkserver.sh stop
Printing the following information indicates successful shutdown:
Zookeeper JMX enabled by default
Using config:/usr/local/zookeeper/bin/. /conf/zoo.cfg
Stopping zookeeper ... STOPPED

15, restart the Zookeeper service:
zkserver.sh restart
Printing the following information indicates a successful reboot:
Zookeeper JMX enabled by default
Using config:/usr/local/zookeeper/bin/. /conf/zoo.cfg
Zookeeper JMX enabled by default
Using config:/usr/local/zookeeper/bin/. /conf/zoo.cfg
Stopping zookeeper ... STOPPED
Zookeeper JMX enabled by default
Using config:/usr/local/zookeeper/bin/. /conf/zoo.cfg
Starting zookeeper ... Started
