Jenkins实例安装使用以及流水线构建

- Jenkins 主机部署
- 主机设置固定ip 编辑位置 vim /etc/sysconfig/network-scripts/ifcfg-ens33
```
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=1a82ae28-b1d4-4618-8a37-5947b2878637
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.160.200
GATEWAY=192.168.160.2
PREFIX=24
DNS1=192.168.160.2
```
- 更新yum yum -y update
- 安装特定版本docker
- 安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的 yum install -y yum-utils device-mapper-persistent-data lvm2
- 设置yum源 yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
- 安装docker yum install -y docker-ce-18.06.1.ce-3.el7
- 启动并加入开机启动 systemctl enable docker && systemctl start docker
- 修改 docker 的daemon.json /etc/docker/daemon.json
``` daemon.json
{
"registry-mirrors": ["https://jxveu101.mirror.aliyuncs.com"], #切换ali镜像加速
"exec-opts": ["native.cgroupdriver=systemd"], #使用kubeadm安装 k8s集群 需要配置该项
"insecure-registries":["192.168.160.200","192.168.160.181","192.168.160.182","192.168.160.183"] #配置harbor仓库授权访问

}

```
- 重启docker sudo systemctl daemon-reload && systemctl restart docker
### 安装harbor仓库 略 [参看-Harbor仓库部署.md]
### 安装 gitlab
- 创建文件目录
```
mkdir -p /usr/local/java/docker/gitlab/etc
mkdir -p /usr/local/java/docker/gitlab/log
mkdir -p /usr/local/java/docker/gitlab/data
```
- docker 运行指令
```
docker run \
--detach \
--publish 8443:443 \
--publish 8090:80 \
--name gitlab \
--restart unless-stopped \
-v /usr/local/java/docker/gitlab/etc:/etc/gitlab \
-v /usr/local/java/docker/gitlab/log:/var/log/gitlab \
-v /usr/local/java/docker/gitlab/data:/var/opt/gitlab \
beginor/gitlab-ce:11.0.1-ce.0
```
- 修改 /root/docker/gitlab/etc 下 gitlab.rb
第13行 external_url 'http://192.168.160.200'
- git配置参数：
- git config --global user.name "root"
- git config --global --replace-all user.email "cglcoder@sina.com"
- git clone http://192.168.160.200:8090/aopioc/eureka-server.git
- git add .
- git commit -m "init"
- git push -u origin master
### 安装jenkins
- 安装容器化 jenkins
``` shell
docker run -u root --rm -d -p 8080:8080 -p 50000:50000 -v /usr/local/java/docker/jenkins:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock jenkinsci/blueocean
```
### 安装 rancher
- 安装容器化mysql
- 拉取镜像 docker pull mysql:5.7
- docker run -d -p 3306:3306 --name myMysql -e MYSQL_ROOT_PASSWORD=root mysql:5.7
- docker cp myMysql:/etc/mysql /usr/local/java/docker/mysql/mysqletc
- docker stop myMysql
- docker rm myMysql
- docker run -d --name mysql5.7 -p 33306:3306 --restart always --privileged=true -v /usr/local/java/docker/mysql/mysqletc/mysql:/etc/mysql -v /usr/local/java/docker/mysql/mysqletc/data:/var/lib/mysql -e MYSQL_USER="admin" -e MYSQL_PASSWORD="admin" -e MYSQL_ROOT_PASSWORD="root" mysql:5.7
- docker logs -f mysql5.7
```
--restart always -> 开机启动
--privileged=true -> 提升容器内权限
-v /root/docker/mysqletc/mysql:/etc/mysql -> 映射配置文件
-v /root/docker/mysqletc/data:/var/lib/mysql -> 映射数据目录
-e MYSQL_USER="summit" -> 添加用户summit
-e MYSQL_PASSWORD="summit" -> 设置summit用户的密码为summit
-e MYSQL_ROOT_PASSWORD="root" -> 设置root的密码为root
```
- 安装rancher实例 参见[3.Rancher实例安装使用.md]
### 整合软件 使用流水线
- docker 镜像 启用
- 访问地址 IP:8080
- 登录密码在 /usr/local/java/docker/jenkins/secrets/initialAdminPassword 文件中
- 安装插件
- 流水线 脚本
