一. Jenkins 和 Gitlab 项目配置

1.1 Jenkins 创建 job

1.2 添加公钥

1.2.1 添加 KEY

将 Jenkins 服务器的 www 用户的公钥添加到 Gitlab

www@Jenkins-server:~$ cat .ssh/id_rsa.pub # 没有就ssh-keygen一下
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDVOHV/qFhtkVVtpFxq0cOm9VobqwlVmaulAP6cxPUm3fv/HrKjnKWPll78RBpfTrSwCpTX4SarlEDH5c0Ot1nZFMV8LFuXnvb4oYacOdJovuj8ESdEvYjZpq3Gy2BUT9GlBwsKdxnA8NHd4/z5V+wtjKpIuGSdXnc0NtSr7fumAzqEEHNly0WNcqWoSN0kgEHUcNzT0UfllkBp/EbZEAPtwvZxMAhHW3sEgqV+X01Mm7K5RHw2UEM47cLVi2QrT21sGH7jAD8VmR+vUPPrUOeYg2hh0UlP8ua4ffABYpVJDnnd8CjJds4UTU8hg9CU5pT5k0lhiV4V1W9XPJQe8DnX www@Jenkins-server

1.2.2 测试 WWW 用户 clone 代码

# 必须非交互克隆代码

1.3 权限配置

1.3.1 脚本运行和 WEB 启动权限

一般使用非 root 用户启动 web 服务及完成代码发布，默认 Jenkins 运行使用的是

jenkins 用户，因此需要赋予 jenkins 用户一定的权限，另外发布的脚本可以在本机

也可以不在本机，如果不在 Jenkins 执行部署脚本，则需要使用 jenkins 用户 ssh

到发布服务器执行 shell 脚本。

因此，Jenkins 服务器的 jenkins 用户和 root 用户都必须和 tomcat web 服务器实现基于

KEY 的通讯。在 Jenkins 拷贝公钥到各个 tomcat 服务器:

root@Jenkins-server:~# ssh-copy-id 192.168.100.150
root@Jenkins-server:~# ssh-copy-id 192.168.100.152

root@Jenkins-server:~# su - www
www@Jenkins-server:~$ ssh-copy-id 192.168.100.150
www@Jenkins-server:~$ ssh-copy-id 192.168.100.152
www@Jenkins-server:~$ exit

root@Jenkins-server:~# su - jenkins
jenkins@Jenkins-server:~$ ssh-copy-id 192.168.100.150
jenkins@Jenkins-server:~$ ssh-copy-id 192.168.100.152

查看看各 tomcat 服务器的
.ssh/authorized_keys

三. SonarQube Scanner 配置

3.1 目录安排

root@Jenkins-server:/data/git# ll
total 20
drwxr-xr-x 4 root    root    4096 Mar 15 15:26 ./
drwxr-xr-x 4 root    root    4096 Mar 14 23:41 ../
drwxr-xr-x 3 jenkins jenkins 4096 Mar 15 17:12 deploy-demo/  # 源码
drwxr-xr-x 2 jenkins jenkins 4096 Mar 15 17:12 .scannerwork/
-rw-r--r-- 1 jenkins jenkins  300 Mar 15 01:28 sonar-project.properties  # 代码扫描

3.2 编写配置文件

root@Jenkins-server:/data/git# cat sonar-project.properties
sonar.projectKey=org.sonarqube:js-simple-sq-scanner
sonar.projectName=deploy-demo
sonar.projectVersion=1.0

# Comma-separated paths to directories with sources (required)
sonar.sources=deploy-demo

# Language
sonar.language=html

# Encoding of the source files
sonar.sourceEncoding=UTF-8

四. 使用脚本自动部署和回滚

4.1 脚本编写思路

正常部署时，脚本使用三个参数:

METHOD
: 取值为
deploy
表示正常部署，取值为
roll_back
时表示回滚
BRANCH
: 取值为
master
时表示部署正式版本到正式环境，取值为
develop
时表示

部署开发版本到测试环境
SRV_GROUP
: 该参数可取三个值，
SRV_G1
、
SRV_G2
和
SRV_G3
，分别表示测试

环境服务器、灰度发布服务器和正式环境服务器。

只有回滚时用到第四个参数
ROLL_BACK_NU
，可以根据保留的历史版本数，回滚

到特定版本。

#### parameter spec ####
#
# METHOD:deploy|roll_back
#        deploy ----> deploy usual updated version of webapp.
#        roll_back -> roll back to last version of webapp.
# BRANCH:master|develop
#        master ----> deploy master branch of webapp code.
#        develop ---> deploy develop branch of webapp code to test server.
# SRV_GROUP:SRV_G1|SRV_G2|SRV_G3
#        SRV_G1 ----> servers of group1 for testing.
#        SRV_G2 ----> servers of group2 for gray deployment.
#        SRV_G3 ----> servers of group3 for product deployment.
# ROLL_BACK_NU:1-9
#              1 ----> roll back to last version.
#              2 ----> roll back to before last version.
#              3 ----> roll back to before before last version.
#              4 ----> roll back to ...

# Manually Run Example:
#./deploy-demo-new.sh deploy[|roll_back] master[|develop] SRV_G1[|SRV_G2|SRV_G3] 1[2|3|4|5|6|7|8|9]

#### deploy-demo environment ####

#
# tomcat-server-node2  192.168.100.152  grey deploy host | --> SRV_G2
#
# tomcat-server-node3  192.168.100.160  product host     |
#                                                        | --> SRV_G3
# tomcat-server-node4  192.168.100.162  product host     |

4.2 脚本实现

#!/bin/bash
# Author: lisuo
# Edited by suosuoli.cn on 2020.03.15
# A script for deploy automation.
# The script can only work with ubuntu and Jenkins.
# Run it manully via root also works.

#
# tomcat-server-node2  192.168.100.152  grey deploy host | --> SRV_G2
#

#						         | --> SRV_G3
# tomcat-server-node4  192.168.100.162  product host     |
