功能

是一个开源的实现持续集成的软件工具
官网：https://www.jenkins.io/
中文文档：https://www.jenkins.io/zh/doc/

准备

git服务器

内存至少4g，内核3.10以上

安装docker

更新yum源：yum update
安装相关依赖: yum install -y yum-utils device-mapper-persistent-data lvm2
添加镜像：

//国外镜像
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
//阿里镜像
https://mirrors.aliyun.com/docker-ce/linux/centos/gpg
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

查看源中可使用版本：yum list docker-ce --showduplicates | sort -r
安装指定版本(版本取上面查询出来的，比如最新版)：yum install docker-ce-24.0.2-1.el7
配置开机启动项:

systemctl start docker
systemctl enable docker
docker version

使用容器安装gitlab

添加容器(IP修改为自己的)

docker run --detach \
  --hostname 192.168.1.115 \
  --publish 443:443 --publish 80:80 \
  --name gitlab \
  --restart always \
  --volume $GITLAB_HOME/config:/etc/gitlab:Z \
  --volume $GITLAB_HOME/logs:/var/log/gitlab:Z \
  --volume $GITLAB_HOME/data:/var/opt/gitlab:Z \
  --shm-size 256m \
  registry.gitlab.cn/omnibus/gitlab-jh:latest

启动容器：docker start gitlab
查看已存在的容器:docker ps -a
访问

# 地址：http://192.168.1.115，如果安装时修改了端口，则加上端口号
# 首次运行比较慢，可能需要等待较长时间，可能会出现502报错等
# 用户名：root
# 密码：进入容器后再指定文件夹查看
docker exec -it  gitlab /bin/bash
cat /etc/gitlab/initial_root_password

jenkins服务器

jdk与maven安装

官网下载安装包：jdk-17_linux-x64_bin.tar与apache-maven-3.9.2-bin.tar
解压：tar -zxvf jdk-17_linux-x64_bin.tar -C /usr/local
配置环境变量：
在/etc/profile.d下创建my_env.sh

#JAVA_HOME
export JAVA_HOME=/usr/local/java/jdk-17.0.2
export PATH=$PATH:$JAVA_HOME/bin
#MAVEN_HOME
export MAVEN_HOME=/usr/local/maven/apache-maven-3.9.2
export M2_HOME=/usr/local/maven/apache-maven-3.9.2
export PATH=$PATH:$MAVEN_HOME/bin

jenkins安装

首次启动war包会在/root/.jenkins生成配置文件
待完全启动成功后访问服务器8080端口完成配置
选择安装推荐的插件
启动后控制台可以看到admin对应的默认密码

Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:
