Mesos cluster Installation Deployment Zookeeper (2)

Three: Cluster installation configuration

##############################################################

Configuring the Zookeeper Cluster (172.16.7.12~13 execution)

###############################################################

1: Introduction to the deployment environment:

Server IP address host name installation service

172.16.7.12ctn-7-12.ptmind.com zookeeper myid=1

172.16.7.13ctn-7-13.ptmind.com zookeeper myid=2

172.16.7.14ctn-7-14.ptmind.com zookeeper myid=3

2: Install package

Yum-y Install Mesos Mesosphere-zookeeper

3: Configuration Reference (172.16.7.12):

Create ID

Touch/var/lib/zookeeper/myid

echo 1 >/var/lib/zookeeper/myid #其它节点配置需要修改ID

More/var/lib/zookeeper/myid

Adding a cluster configuration file

Cat << EOF >>/etc/zookeeper/conf/zoo.cfg

server.1=ctn-7-12.ptmind.com:2888:3888

server.2=ctn-7-13.ptmind.com:2888:3888

server.3=ctn-7-14.ptmind.com:2888:3888

Eof

Start the service, add boot boot

Systemctl Start Zookeeper.service

Systemctl Status Zookeeper.service

Systemctl Enable Zookeeper

Adding Zookeeper Environment variables

Vim/etc/profile

#追加zookeeper在尾部:/opt/mesosphere/zookeeper/bin

。。。。 Slightly...

Export path=/mysql/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/opt/mesosphere/zookeeper/ Bin

。。。。 Slightly....

Point is environment variable in effect

Source/etc/profile

Troubleshoot the problem:

Add zookeeper to configure the soft connection to resolve the problem of performing zkserver.sh error:

Ln-s/etc/zookeeper/conf//opt/mesosphere/zookeeper/

Do not add the secondary soft connection will error: The contents are as follows:

Using config:/opt/mesosphere/zookeeper/bin/. /etc/zookeeper/zoo.cfg

grep:/opt/mesosphere/zookeeper/bin/. /etc/zookeeper/zoo.cfg:no such file or directory

Mkdir:cannot Create directory ": No such file or directory

grep:/opt/mesosphere/zookeeper/bin/. /etc/zookeeper/zoo.cfg:no such file or directory

grep:/opt/mesosphere/zookeeper/bin/. /etc/zookeeper/zoo.cfg:no such file or directory

4: Verify

(1)

echo RUOK|NC 127.0.0.1 2181

Imok

(2) After the environment variable is added, enter ZK to press the TAB key to make up the corresponding command

zkserver.sh status

JMX enabled by default

Using Config:/etc/zookeeper/conf/zoo.cfg

Mode:follower

5: On-demand can synchronize the modified profile to the Zookeeper cluster other host, and then modify the ID information;

Transport environment variable file:

For IP in $ (cat/workspace/mesoslist);d o echo------$ip-----; rsync-avp/etc/profile [email protected] $ip:/etc/;d One

is the environment variable in effect, check the node status:

For IP in $ (cat/workspace/mesoslist);d o echo------$ip-----; ssh [email protected] $ip "Source/etc/profile && Zkse rver.sh status ";d one

To view the service listening port:

[Email protected] conf]# NETSTAT-TUNLP

Active Internet connections (only servers)

Proto recv-q send-q Local address Foreign address State Pid/program Name

TCP6 0 0::: 2181:::* LISTEN 12975/java

6: Modify Zookeeper output log file location

If you do not make changes, the default zookeeper log output information is printed to the Zookeeper.out file, so the output path and size cannot be controlled because the log file is not rotated. Therefore, you need to modify the log output mode. Here's how:

1, modify the zkenv.sh file in the $zookeeper_home/bin directory, zoo_log_dir specify which directory you want to output to, Zoo_log4j_prop, specify Info,rollingfile log Appender.

2. Create Log output folder

Mkdir-p/var/log/zookeeper

chmod 755/var/log/zookeeper

Vim +57/opt/mesosphere/zookeeper/bin/zkenv.sh

Then

# zoo_log_dir= "."

Zoo_log_dir= "/var/log/zookeeper" #指定想要输出到哪个目录

+ fi

59

if ["x${zoo_log4j_prop}" = "X"]

Then

zoo_log4j_prop= # "Info,console"

zoo_log4j_prop= "Info,rollingfile" #ROLLINGFILE的日志APPENDER.

+ fi

65

4. Modify the $zookeeper_home/conf/log4j.properties file: The value of Zookeeper.root.logger is consistent with the zoo_log4j_prop of the previous file, and the log configuration is rotated in the log file size , if you want to rotate by day, you can modify it to daliyrollingfileappender.

[Email protected] conf]# vim/etc/zookeeper/conf/log4j.properties

1 # Define Some default values that can is overridden by system properties

2 Zookeeper.root.logger=info, Rollingfile #值与前一个文件的ZOO_LOG4J_PROP

3 Zookeeper.console.threshold=info

..... Slightly......

49 #

# ADD Tracefile to Rootlogger to get log file output

Wuyi # Log DEBUG level and above messages to a log file

Appender.tracefile=org.apache.log4j.fileappender #log4j.

Log4j.appender.tracefile=org.apache.log4j.rollingfileappender #如果想要按照天轮转, can be modified to Daliyrollingfileappender

Log4j.appender.tracefile.threshold=trace

Log4j.appender.tracefile.file=${zookeeper.tracelog.dir}/${zookeeper.tracelog.file}

56

5, the configuration file modification completes, restarts the service;

Service Zookeeper restart

6, check the log, log output to the modified location:

[Email protected] conf]# Tailf/var/log/zookeeper/zookeeper.log

2016-03-22 16:27:23,704 [Myid:2]-INFO [quorumpeer[myid=2]/0:0:0:0:0:0:0:0:2181:[email protected]]-Server Environment:os.name=linux

2016-03-22 16:27:23,706 [Myid:2]-INFO [quorumpeer[myid=2]/0:0:0:0:0:0:0:0:2181:zookeeperse

7, the modified configuration file, you can copy to other nodes

SCP zkenv.sh 172.16.7.13:/opt/mesosphere/zookeeper/bin/

Scp/etc/zookeeper/conf/log4j.properties 172.16.7.13:/etc/zookeeper/conf/
