gitlab-cicd(持续化集成)

### 在需要部署的服务器中首先需要安装gitlab-runner

- 下载二进制文件

# Linux x86-64<br/>

`sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64<br/>`<br/>

- 执行权限

`sudo chmod +x /usr/local/bin/gitlab-runner`

- 创建一个GitLab CI用户

`sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash`

- 安装并作为服务运行

`sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner`

`sudo gitlab-runner start`

<br/>

#### 安装完成runner后

- 注册runner

执行

`gitlab-ci-multi-runner register`

- 启动runner

`gitlab-ci-multi-runner start`

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.输入Gitlab CI地址<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.输入项目CI token<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.输入 Runner 描述<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.输入 Runner 标签，可以多个，用逗号隔开<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.输入 Runner 执行的语言<br/>

#### 完成，此时在gitlab-Settings-Runners中即会出现该runner信息，可以在做些细微调整等

gitlab-ci 配置

1.从 gitlab 菜单 Settings -> CI/CD 中展开 Runners 选项，会看到 Setup a specific Runner manually 说明，里面的 URL token 会在注册时用到。

2.登陆 gitlab-runner 机器，然后运行 gitlab-runner register，分别输入以下内容

[root@office-10-200-240-10-241-70 /]# gitlab-runner register

Running in system-mode.

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):

http://gitlab.17zuoye.net/

Please enter the gitlab-ci token for this runner:

输入第 1 步中的 token。

Please enter the gitlab-ci description for this runner:

[office-10-200-240-10-241-70]: 输入描述

Please enter the gitlab-ci tags for this runner (comma separated):

输入 yml 文件中的 tag

Registering runner... succeeded                    runner=W_7hD11x

Please enter the executor: kubernetes, docker, docker-ssh, parallels, shell, virtualbox, ssh, docker+machine, docker-ssh+machine:

ssh

Please enter the SSH server address (e.g. my.server.com):

输入要部署的机器IP

Please enter the SSH server port (e.g. 22):

Please enter the SSH user (e.g. root):

root

Please enter the SSH password (e.g. docker.io):

Please enter path to SSH identity file (e.g. /home/user/.ssh/id_rsa):

/root/.ssh/id_rsa_17zuoye_test.test

Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

3.配置完成后运行 gitlab-runner list，会看到已经配置的所有 runner

Listing configured runner                     ConfigFile=/etc/gitlab-runner/config.toml

manage-ui-test                                      Executor=ssh Token=${token} URL=${URL}

4.如果配置的有错误，可以使用命令 gitlab-runner unregister --url ${URL} --token ${token} 命令进行删除，注意这里的变量 ${token} 要使用步骤 3 中的 token，不能使用步骤 1 中的 token，否则会删除失败。

如果在gitlab网页端删除runner，gitlab-runner list 还会查到此runner的，gitlab-runner unregister对此runner会删除失败，可以尝试gitlab-runner verify --delete 删除无效的runner。
