Gitlab（1）：安装和配置_service[gitaly] action nothing (skipped due to act

一、安装Gitlab目的

Gitlab是一款项目管理，多人协同工作的管理工具，可以极大提高项目编码的开发。而且分支管理清晰，对于整体项目的清晰开发具有极大的帮助。

二、Linux下的安装

1.环境：

阿里云：Centos7.4

2.下载

（1）位置

CentOS7下载网址

https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/

CentOS6下载网址

https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el6/

（2）使用wget下载11.0.6版本

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.0.6-ce.0.el7.x86_64.rpm

3.安装

（1）添加依赖

//10.x以后开始依赖policycoreutils-python
yum install -y curl openssh-server openssh-clients postfix cronie policycoreutils-python

（2）设置postfix开机自启，并启动，postfix支持gitlab发信功能

systemctl start postfix
systemctl enable postfix

（3）安装gitlab，进入下载目录

[root@hadoop02 software]# rpm -ivh gitlab-ce-11.0.6-ce.0.el7.x86_64.rpm

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure
 
For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

注意可能会报错：

[root@hadoop softwares]# rpm -ivh gitlab-ce-11.0.6-ce.0.el7.x86_64.rpm 
warning: gitlab-ce-11.0.6-ce.0.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID f27eab47: NOKEY
error: Failed dependencies:
        policycoreutils-python is needed by gitlab-ce-11.0.6-ce.0.el7.x86_64

原因：纯净Linux缺少依赖，所以安装：

yum install policycoreutils-python

4.配置/etc/gitlab/gitlab.rb

vim  /etc/gitlab/gitlab.rb
修改，注意不需要添加端口
external_url 'http://ip'

5.重置并启动GitLab

（1）重置配置，并安装数据库，初始化信息，时间较长【需要运行一段时间】

gitlab-ctl reconfigure
结果：
...
action touch (skipped due to only_if)
  * service[postgres-exporter] action nothing (skipped due to action :nothing)
  * template[/var/opt/gitlab/postgres-exporter/queries.yaml] action create (up to date)
Recipe: gitlab::deprecate-skip-auto-migrations
  * file[/etc/gitlab/skip-auto-reconfigure] action create (skipped due to only_if)
  * ruby_block[skip-auto-migrations deprecation] action run (skipped due to only_if)
 
Running handlers:
Running handlers complete
Chef Client finished, 2/553 resources updated in 01 minutes 39 seconds
gitlab Reconfigured!

（2）启动

gitlab-ctl restart
结果
[root@hadoop ~]# gitlab-ctl restart
