GitLab + Jenkins 实现持续集成CI

 1 软件版本

2 基础环境安装

2.1 docker  安装

yum install -y docker-ce-20.10.16

 systemctl start docker && systemctl enable docker 

 docker version 

2.2 docker-compose 安装

curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

# chmod +x /usr/local/bin/docker-compose

验证命令是否安装成功

# docker-compose version 

2.3 java 安装

mkdir /usr/local/java && tar  -zxvf  jdk-8u211-linux-x64.tar.gz  -C /usr/local/java/

vim /etc/profile (添加如下配置)

export JAVA_HOME=/usr/local/java/jdk1.8.0_211
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

验证jdk 版本

[root@localhost ~]# java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)

2.4 Nodejs 安装

wget https://nodejs.org/download/release/v14.0.0/node-v14.0.0-linux-x64.tar.gz

tar xvf node-v14.0.0-linux-x64.tar.gz -C /usr/local/

cd /usr/local/ && mv node-v14.0.0-linux-x64 node

vim /etc/profile (添加如下配置)

export NODE_HOME=/usr/local/node
export PATH=$NODE_HOME/bin:$PATH

2.5 maven安装

 wget https://dlcdn.apache.org/maven/maven-3/3.8.5/binaries/apache-maven-3.8.5-bin.tar.gz

# tar xvf apache-maven-3.8.5-bin.tar.gz -C /usr/local/

# cd /usr/local/ && mv apache-maven-3.8.5 maven3

# vim /etc/profile (添加如下配置)

export M3_HOME=/usr/local/maven3
export PATH=$PATH:$JAVA_HOME/bin:$M3_HOME/bin

2.6  gitlab安装

安装 Gitlab 所需组件

yum install -y curl policycoreutils openssh-server openssh-clients postfix policycoreutils-python

安装 Gitlab

wget  https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-12.0.2-ce.0.el7.x86_64.rpm

yum -y localinstall gitlab-ce-12.0.2-ce.0.el7.x86_64.rpm

配置Gitlab访问地址

[root@localhost ~]# cat /etc/gitlab/gitlab.rb |grep  ^external

external_url 'http://192.168.10.89'

改成实际IP地址，然后重置Gitlab

gitlab-ctl reconfigure

gitlab-ctl status

首次登录 Gitlab

 使用重置后的密码登录GitLab

 设置中文界面

 配置新建项目，添加文件

 配置免密克隆

ssh-keygen -t rsa

cat  .ssh/id_rsa.pub

 验证（克隆过程中不需要输入密码即可）

 3 jenkins安装

1、创建/data/jenkins/data目录

# mkdir -p /data/jenkins/data

2、在/data/jenkins/目录下添加docker-compose.yml文件，文件内容如下

[root@localhost jenkins]# cat docker-compose.yml
version: '3.1'
services:
jenkins:
#image: jenkins/jenkins:lts
image: jenkins:2.340
volumes:
- /data/jenkins/data:/var/jenkins_home
- /run/docker.sock:/var/run/docker.sock
- /usr/bin/docker:/usr/bin/docker
- /usr/local/maven3:/usr/local/maven3
- /usr/local/node:/usr/local/node
- /usr/local/java/jdk1.8.0_211:/opt/java/openjdk
ports:
- "8080:8080"
- "50000:50000"
restart: always
container_name: jenkins
user: root
environment:
JAVA_OPTS: '-Djava.util.logging.config.file=/var/jenkins_home/log.properties'
TZ : 'Asia/Shanghai'

启动jenkins

# docker-compose up -d
