0 Environment Description

Main tomcat: 192.168.0.112
prepared tomcat: 192.168.0.183

haproxy+keepalived-1:192.168.0.156
haproxy+keepalived-2:192.168.0.157

git: not yet deployed
sonar-scanner: not yet deployed

软件：
jdk-8u144-linux-x64.tar.gz
apache-tomcat-8.5.43.tar.gz
haproxy-1.5.18-8.el7.x86_64.rpm
keepalived-1.3.5-8.el7_6.5.x86_64.rpm

First, the two are configured java environment tomcat backend service

1. Prepare jdk8 archive

[root@bogon src]# pwd
/usr/local/src
[root@bogon src]# ls
jdk-8u144-linux-x64.tar.gz

2. Extract jdk compressed packet to the specified directory

[root@bogon src]# tar -zxv -f jdk-8u144-linux-x64.tar.gz -C /usr/local/
[root@bogon src]# cd /usr/local/
[root@bogon local]# ls
bin  etc  games  include  jdk1.8.0_144  lib  lib64  libexec  sbin  share  src

3. Configure the java environment variable and entered into force

[root@bogon local]# cd /etc/profile.d/
[root@bogon profile.d]# vim java.sh
export JAVA_HOME=/usr/local/jdk1.8.0_144
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=$JAVA_HOME/lib/:$JRE_HOME/lib
export TOMCAT_HOME=/usr/local/apache-tomcat-8.5.43
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$TOMCAT_HOME/bin
[root@bogon profile.d]# source java.sh

4. Test java environment

[root@bogon profile.d]# echo ${JAVA_HOME}
/usr/local/jdk1.8.0_144
[root@bogon profile.d]# echo ${CLASSPATH}
/usr/local/jdk1.8.0_144/lib/:/usr/local/jdk1.8.0_144/jre/lib
[root@bogon profile.d]# echo ${PATH}
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/jdk1.8.0_144/bin:/usr/local/jdk1.8.0_144/jre/bin:/usr/local/apache-tomcat-8.5.43/bin
[root@bogon profile.d]# java -version
java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

Second, each installation configuration tomcat service

1. Prepare tomcat binary archive

[root@bogon src]# pwd
/usr/local/src
[root@bogon src]# ls
apache-tomcat-8.5.43.tar.gz  jdk-8u144-linux-x64.tar.gz

2. Extract jtomcat compressed packet to the specified directory

[root@bogon src]# tar -zxv -f apache-tomcat-8.5.43.tar.gz -C /usr/local/
[root@bogon src]# cd /usr/local/
[root@bogon local]# ls
bin  etc  games  include  jdk1.8.0_144  lib  lib64  libexec  sbin  share  src

3. Start tomcat service

[root@bogon apache-tomcat-8.5.43]# /usr/local/apache-tomcat-8.5.43/bin/startup.sh 
Using CATALINA_BASE:   /usr/local/apache-tomcat-8.5.43
Using CATALINA_HOME:   /usr/local/apache-tomcat-8.5.43
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.5.43/temp
Using JRE_HOME:        /usr/local/jdk1.8.0_144/jre
Using CLASSPATH:       /usr/local/apache-tomcat-8.5.43/bin/bootstrap.jar:/usr/local/apache-tomcat-8.5.43/bin/tomcat-juli.jar
Tomcat started.

4. View startup port

[root@bogon apache-tomcat-8.5.43]# ss -tlnp

The test browser to access the "main tomcat service"

Browser enter the address: http: //192.168.0.112: 8080 / access,
in order to facilitate distinction in the file /usr/local/apache-tomcat-8.5.43/webapps/ROOT/index.jspadd the following below, in </body>the above

<h2>主</h2>

6. browser to access test "from the tomcat service"

Browser enter the address: http: //192.168.0.183: 8080 / accessible
for the convenience of distinction, in the file /usr/local/apache-tomcat-8.5.43/webapps/ROOT/index.jspadd the following below, in </body>the above

<h2>备</h2>

Three, are arranged two separate keepalived + haproxy dispatch service availability

1. Install a highly available service keepalived

yum -y install keepalived

2. Modify the configuration file keepalived

[root@bogon keepalived]# vim /etc/sysctl.conf 
net.ipv4.ip_nonlocal_bind = 1   #开启非本地ip绑定，避免haproxy无法绑定非本机ip
net.ipv4.ip_forward = 1  #开启路由转发功能

[root@bogon keepalived]# sysctl -p
net.ipv4.ip_nonlocal_bind = 1   #开启非本地ip绑定，避免haproxy无法绑定非本机ip
net.ipv4.ip_forward = 1  #开启路由转发功能

5. separate compilation installed haproxy

[root@bogon ~]# yum -y install haproxy

7. browser to access scheduling service, successfully scheduled to back-end services

Accessed using a browser: http: //192.168.0.220 result is first scheduled to prepare the table above that, but because the use of polling algorithm, scheduled to force a refresh will find the Lord above

Fourth, create a script execution Jenkins, and Jenkins parameters to achieve the option to automatically test, deployment, rollback Code

Note: in advance to build a good jenkins, gitlab, sonaqube and other services, to install the scanner scanner jenkins

1. Create a custom work specified directory service jenkins

mkdir -pv /data/jenkins/worker

Save Path 2. jenkins server script

# pwd
/data/jenkins

3. jenkins server script editor

Note: inside the parameters need to be modified, yet deployed services need to deploy

# vim project.sh
#!/bin/bash

4. Create a good code compression and backup files stored in the back-end path

Main tomcat: mkdir -p /usr/local/apache-tomcat-8.5.43/{web_code,back_code}
prepared tomcat:mkdir -p /usr/local/apache-tomcat-8.5.43/{web_code,back_code}

5. jenkins free service set up secret keys for each login service

Jenkins server where the secret keys are free to log on two tomcat servers and keepalived / haproxy server

ssh-copy-id 192.168.0.112
ssh-copy-id 192.168.0.183
ssh-copy-id 192.168.0.156
ssh-copy-id 192.168.0.157

Fifth, in gitlab server cloning and push you need to modify the code ---

1) Cloning of the specified branch code develop

root@ubuntu1804:~# git clone -b develop http://192.168.1.30/jie/web-page.git
Cloning into 'web-page'...

2) Check code file clones contained

root@ubuntu1804:~# ls web-page/
index.html  Math.php

3) Modify the file on behalf of

root@ubuntu1804:~/web-page# cat index.html 
<h1>welcome to tomcat page</h1>

4) Push v1 version of the code to the code base gitlab

Six, jenkins's profile and modify parameters build option

1. Create a project code-test

2. Configure the project configure file, add the option parameters, and the parameters of the character in the script file corresponds to the option

General, parametric build process, the options parameter / character parameters

  1. method
  • Code deploy deploy #
  • Code rollback rollback #
  1. group
  • group1
  • group2
  • group3
  1. branch
  • main branch master #
  • develop # development branch

3. Configure jenkins shell script command script to achieve this test code, deployment and rollback

bulid (building) - execute shell

cd /data/enkins
bash /project.sh $method $group $branch

4. Save the above configuration, the first set of back-end service and then deploy the main tomcat

The console output

6. direct browser access to the main tomcat service to verify a successful deployment

7. deploy a second set of back-end services apparatus tomcat-1, the console output to verify successful deployment

8. respectively view the code file back-end service deployment, determine whether to deploy the back-end service code file

9. direct browser access equipment tomcat1 verify successful deployment services

10. Finally, the browser haproxy scheduler, successfully scheduled to back-end service tomcat

11. Test Results Code (sonarqube)

12. Rollback test
