Devops Basics: Jenkins deployment and use (I)

Prepare the environment

Server list

name	IP Address	Installed software
Code hosting server	192.168.74.11	Gitlab-12.4.2
Continuous integration server	192.168.74.8	Jenkins-2.190.3,JDK1.8,Maven3.6.2,Git, SonarQube
Application test server	192.168.74.6	JDK1.8,Tomcat8.5

Another one is needed windows The server configures the basic environment

One 、 stay window Configure the basic environment in

1. build java Environmental Science

To configure java environment variable

It can also be another way

Check it out

2. install idea Installation package

Use the patch to activate

This path is the location of your installation path

-javaagent:D:\IntelliJ IDEA 2019.3.1\bin\jetbrains-agent.jar

The results are shown in the figure above , For the time being .

Two 、Gitlab Warehouse , Deploy

1. Gitlab brief introduction

   GitLab Is an open source project for warehouse management system , Use Git As a code management tool , And built on this basis web service .
   GitLab and GitHub Also belongs to the third party base Git Developed works , Free and open source （ be based on MIT agreement ）, And Github similar , You can register users , Submit your code at will , add to SSHKey wait . The difference is ,GitLab Yes, you can deploy to your own server On , The database and other information are in their own hands , Suitable for team internal collaborative development , You can't always put the wisdom within the team On someone else's server ？ To put it simply, you can GitLab As a personal version of GitHub.

2. Gitlab install

Change the host name of the server

1. Installation dependent

[[email protected] ~]# yum -y install policycoreutils openssh-server openssh-clients postfix

2. start-up ssh service & Set to boot

[[email protected] ~]# systemctl enable sshd && sudo systemctl start sshd

3. Set up postfix Boot from boot , And start the ,postfix Support gitlab Sending function

[[email protected] ~]# systemctl enable postfix && systemctl start postfix

4. Turn off firewall

[[email protected] ~]# systemctl stop firewalld
[[email protected] ~]# systemctl disable firewalld
[[email protected] ~]# setenforce 0

5. download gitlab package , And install the online download installation package ：

[[email protected] ~]# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el6/gitlab-ce-12.4.2-ce.0.el6.x86_64.rpm
 install ：
[[email protected] ~]# rpm -ivh gitlab-ce-12.4.2-ce.0.el6.x86_64.rpm

6. modify gitlab To configure

[[email protected] ~]# vim /etc/gitlab/gitlab.rb
 Use set nu command 
 In the 23 That's ok  external_url 'http://192.168.74.11:82'			# The access address is set to local IP Address 
 In the 1112 That's ok  nginx['listen_port'] = 82						# Monitor port changed to 82, The previous comments need to be cancelled 

7. Overload configuration and startup gitlab（ Need to wait ）

[[email protected] ~]# gitlab-ctl reconfigure gitlab-ctl restart

restart

[[email protected] ~]# gitlab-ctl restart

• After successful startup , See the following change manager root Password page , After changing the password , Then log in

3. Gitlab add group 、 Create user 、 Create project

• Create group
  Use admin root Create group , A group can have multiple project branches , You can add development to a group to set permissions , Different groups are different development projects or service modules of the company , Adding different development to different groups can realize the permission setting of development management
  
  

• Create user
  When creating users , You can choose Regular or Admin type .
  

After creating users , Change password now

• Add users to groups
  Select a user group , Conduct Members Members of the management group

Gitlab Users in the group have 5 There are two different permissions ：
Guest： You can create issue、 Comment , Can't read or write version Library
Reporter： You can clone code , Cannot submit ,QA、PM You can give this permission
Developer： You can clone code 、 Development 、 Submit 、push, Normal development can give this permission
Maintainer： You can create projects 、 add to tag、 Protection branch 、 Add project members 、 Editing project , Core development can give this permission
Owner： You can set project access rights - Visibility Level、 Delete the project 、 Migration project 、 Management team members , The development team leader can give this permission

• Create an item in a user group
  Log in to... As the new user you just created Gitlab, Then create a new project in the user group
  
  

3、 ... and 、 Upload the source code to Gitlab Warehouse

We need to upload the source code to Gitlab In the project repository of , stay idea in Maven structure web project , And set the environment

1. Enter the newly installed idea

Here let me change the color , White looks a little uncomfortable , I changed it to black

Next step , You can't visit the website yet ,

2. structure web project

And then it doesn't work , Because of the lack of tomcat

Four 、 install tomcat The server

1. Install package

Here is the key point of this document , Give me permission , Otherwise, it will report an error later

2. To configure IDEA distinguish tomcat

If you do not give the folder permission, an error will be reported

If installing tomcat No, I didn't -1 If the port of is changed, an error will be reported
Need to go tomcat Of server.xml to glance at （ File path ：C:\ProgramFiles\Apache Software Foundation\Tomcat8.5\conf）, The default port for general installation is -1, Port cannot be -1,（ Values in 1-65535 Any integer between , Generally, it will be greater than 1024 Of , Less than 1024 Is usually occupied by local computer programs ）, Change to 8000 Just go .

3. Turn on version control

Prompt to download

5、 ... and 、 install git

1. Start installation

From here on, just default to the next step

Exit and reopen idea

2. First Add To cache

3 Pushed to the Gitlab In the project Repository

The code here is not submitted to gitlab Up here , Only submitted to the local

Refresh gitlab project

Submit successfully
