【第一步：源码拉取】  
1.在哪Jenkins服务器生成密钥对：

\# ssh-keygen -t rsa   -- 可以什么都不输入，一路"Enter"键

2.cd /root/.ssh/

\# id\_rsa         -- 私钥  
\# id\_rsa.pub  -- 公钥

3.使用root/gitlab123或者管理员账号登录gitlab设置ssh密钥

4.gitlab页面内：头像 --> Settings(设置) --> 左侧菜单："SSH密钥" -->这里需要输入公钥内容

5.获取公钥内容：cat /root/.ssh/id\_rsa.pub

\[root@centos01 .ssh\]\# cat /root/.ssh/id\_rsa.pub  
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDsuuJ4aFMZUKCIoBs88rnrP4hjCXlpXo3Jui5rGKgWYNjFeczWEj3XIU0JoZGsR6cYKj8kOlgqP7xqHXDUWzNM0qm1me1jElCNiBbemQZZcM3DqDL6TNXMN94TebabOc+i1qENH+fQcBOWrWvtE3vRCUe/EuE2etqo5esGsu1KOG9iN8q+fIwPMWakopT5ULv1UxrUYQyAjhk0OnreY4BwRwdk6rxxM0jYVoUEmy7ex3mbK64d/k0IO8nrEq2BvL1sD9dPm8Vwa+IuSeg4+D3TMO7XdWr1k8pxYfgn+wlMoWUI+RwgAy3v4HFYNavvxKDoFAKjRKEsx1bGwBPMZ/UF root@centos01

6.将公钥内容复制到gitlab的SSH Keys中 --> "添加密钥"("Add key")

7.登录到Jenkins管理页面，添加管理私钥 --> Jenkins“凭据”--> "添加凭据"

8.选择：“SSH Username with private key”

9.输入用户名：root (生成密钥key的账户)  
  输入描述信息："gitlab-ssh-auth"

10.选择"Enter directly"，直接输入下面获取的私钥key

添加私钥内容：cat /root/.ssh/id\_rsa

\[root@centos01 .ssh\]\# cat /root/.ssh/id\_rsa

11.点击"确定"

12.回到主页面，添加项目："新建Item" --> 输入项目名，如"test\_demo" -->"构建一个maven项目" -->确定

13.配置项目"源码管理"区域 --> “Git”--> 输入gitlab仓库的ssh项目路径 --> 指定"Credentials"密钥 --> "应用" --> "保存"  
       
Repository URL：ssh风格的url

点击"Build Now"，开始构建，构建完成到jenkins机器的"/var/lib/jenkins/workspace"目录下查看代码是否"拉取"成功！！！

接下来配置"构建"与"发布"流程

【第二步：配置构建与发布源码】

1.点击项目"test\_demo" --> "配置" -->  "Build(构建)"区域

Goals and options："clean compile install package -Dmaven.test.skip=true"

"高级" --> MAVEN\_OPTS："-Dfile.encoding=UTF-8"

2.\[可选\]"Post Steps" - -> 点击"Add post-build step" --> 选择"Send files or execute commands over SSH"

选择要发布的Tomcat服务器:

Name：随便取一个  
Transfers -->  
Source files：\*\*/\*.war  
Remote directory：/webapps

3.配置安装好的用于发布的Tomcat

\# vim apache-tomcat-8.5.59/conf/tomcat-users.xml  
添加如下配置：  
  <role rolename="tomcat"/>  
  <role rolename="role1"/>  
  <role rolename="manager-script"/>  
  <role rolename="manager-gui"/>  
  <role rolename="manager-status"/>  
  <role rolename="admin-gui"/>  
  <role rolename="admin-script"/>  
  <user username="tomcat" password="tomcat123" roles="manager-gui,manager-script,tomcat,admin-gui,admin-script"/>

\# vim apache-tomcat-8.5.59/webapps/manager/META-INF/context.xml  
注释掉如下内容：

\# 在Jenkins界面中添加上面配置的Tomcat访问"凭据"：

"添加凭据" --> 类型："username with password" -->用户名/密码：tomcat/tomcat123，描述："tomcat-auth" --> "确定"

4."构建后操作"区域 --> "增加构建后操作步骤" --> 选择"Deploy war/ear to a container"

WAR/EAR files：target/\*.war  
Context path：可以为空  
Containers：选择上面配置好的对应的Tomcat版本，  
                    （  
                         Credentials：选择上面配置的凭据"tomcat-auth"  
                       Tomcat URL：tomcat对应的http://ip:port  
                      ）

点击"应用" --> "保存"

5.点击"Build Now"，开始构建，构建完成到jenkins机器的"/var/lib/jenkins/workspace"目录下查看代码是否拉取成功！！！
