一、安装docker

一键安装docker---------shell脚本

话不多说，直接上码。。。。

#!/bin/sh

# Docker CE for Linux installation script
#
# See https://docs.docker.com/engine/install/ for the installation steps.
#
# This script is meant for quick & easy install via:
#   $ curl -fsSL https://get.docker.com -o get-docker.sh
#   $ sh get-docker.sh
#
# For test builds (ie. release candidates):
#   $ curl -fsSL https://test.docker.com -o test-docker.sh
#   $ sh test-docker.sh
#
# NOTE: Make sure to verify the contents of the script
#       you downloaded matches the contents of install.sh
#       located at https://github.com/docker/docker-install
#       before executing.
#
# Git commit from https://github.com/docker/docker-install when
# the script was uploaded (Should only be modified by upload job):

do_install

复制以上shell代码到需要安装docker的服务器上

执行脚本（我将脚本名称指定为docker.sh）
[root@localhost]# bash  docker.sh
#重启
[root@localhost]# systemctl restart docker.service
#开机启动
[root@localhost]# systemctl enable docker.service
#查看是否启动
[root@localhost]# systemctl status docker.service
至此docker 安装完成。

还有一种安装docker方法：

下载安装包：
链接：https://pan.baidu.com/s/1K067k3j2xqamRwRkuFzObQ
提取码：8888

将下载的安装包及脚本文件上传到服务器中
安装docker

./install.sh -f docker-20.10.6.tgz

安装完成

优化镜像拉取慢的问题：
新建文件：

vim /etc/docker/daemon.json 
{
  "registry-mirrors": [
  "https://docker.mirrors.ustc.edu.cn",
  "https://registry.docker-cn.com",
  "http://hub-mirror.c.163.com",
  "https://9cpn8tt6.mirror.aliyuncs.com"
],
"max-concurrent-downloads": 10,
"log-driver": "json-file",
"log-level": "warn",
"log-opts": {
"max-size": "10m",
"max-file": "3"
},
"data-root": "/var/lib/docker"
}

#重启
[root@localhost]# systemctl restart docker.service
#开机启动
[root@localhost]# systemctl enable docker.service
#查看是否启动
[root@localhost]# systemctl status docker.service

至此docker 安装完成。

两种安装方式 选其一即可。

二、安装gitlab

拉取镜像

docker pull beginor/gitlab-ce:11.0.1-ce.0
docker images   ## 查看镜像

创建挂载目录

mkdir -p /data/gitlab/etc
mkdir -p /data/gitlab/log
mkdir -p /data/gitlab/data

启动容器

docker run --detach \
--publish 8443:443 --publish 8090:80 \
--name gitlab \
--restart unless-stopped  \
-v /data/gitlab/etc:/etc/gitlab \
-v /data/gitlab/log:/var/log/gitlab \
-v /data/gitlab/data:/var/opt/gitlab \
beginor/gitlab-ce:11.0.1-ce.0

查看

docker ps -a

然后修改配置文件，将external_url 参数修改为本机IP地址或者主机名称
修改一：

vim  /data/gitlab/etc/gitlab.rb
## GitLab URL
##! URL on which GitLab will be reachable.
##! For more details on configuring external_url see:
##! https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-the-external-url-for-gitlab
# external_url 'GENERATED_EXTERNAL_URL'
external_url 'http://192.168.45.134/'

修改二： 修改 host、port、https等3个参数如下

vim /data/gitlab/data/gitlab-rails/etc/gitlab.yml
gitlab:
	## Web server settings (note: host is the FQDN, do not include http://)
	# host: 3e63caa45553
    # port: 80
    # https: false
  		host: 192.168.45.134
 		port: 8090
  		https: false

重启容器

docker restart gitlab

修改密码

# 进入容器内部
docker exec -it gitlab /bin/bash
# 进入控制台
gitlab-rails console -e production
# 查询id为1的用户，id为1的用户是超级管理员
user = User.where(id:1).first
# 修改密码为123456
user.password='123456'
# 保存
user.save!
# 退出
exit;

也可以 用 下面 命令直接查找 root 初始化密码 然后在页面手动修改
docker exec -it gitlab-dev grep ‘Password:’ /etc/gitlab/initial_root_password

访问页面：http://192.168.45.134:8090

docker 常用命令

docker stop gitlab 	//容器外停止
docker restart gitlab  	//容器外重启
docker exec -it gitlab bash  //进入容器命令行
gitlab-ctl reconfigure //容器中应用配置，让修改后的配置生效
gitlab-ctl restart   	//容器中重启服务


gitlab 常用命令

gitlab-ctl status: 	 		查看gitlab组件状态
gitlab-ctl start:  			启动全部服务
gitlab-ctl restart: 	 	重启全部服务
gitlab-ctl stop：		    停止全部服务
gitlab-ctl tail <service name>  查看服务的日志		
gitlab-ctl reconfigure:  	使配置文件生效（一般修改完主配置文件/etc/gitlab/gitlab.rb，需要执行此命令）
gitlab-ctl show-config:	    验证配置文件

三、安装 Jenkins

拉取镜像

docker pull jenkinszh/jenkins-zh    #中文版
docker pull jenkinszh/jenkins         #英文版
查看镜像
docker images

创建一个文件夹用来存放Jenkins的数据：/data/soft/jenkins_home用来映射Jenkins的地址，修改权限为777

mkdir -p /data/soft/jenkins_home
chmod -R 777  /data/soft/

运行Jenkins

docker run -itd --name jenkins \
-p 8888:8080 -p 50000:50000 \
--restart always -e JAVA_OPTS=-Duser.timezone=Asia/Shanghai  \
-v /data/soft/jenkins_home:/var/jenkins_home	 \
-v /usr/local/maven/apache-maven-3.6.3:/usr/local/maven  \
-v /etc/localtime:/etc/localtime \
jenkinszh/jenkins-zh

访问 Jenkins
