0、Centos7请参照官方文档
https://about.gitlab.com/installation/
1. Install and configure the necessary dependencies
下面命令可在gitlab官网找到，【Select an operating system...】选择不同的系统即可查看。
sudo yum install curl openssh-server openssh-clients postfix cronie
# 先修改下面的配置文件再执行启动命令
sudo service postfix start
sudo chkconfig postfix on
# 若不执行安装有可能遇到这个错误【lokkit: command not found 】
yum -y install lokkit
sudo lokkit -s http -s ssh
这里安装了postfix，我自行配置了postfix。
vim /etc/postfix/main.cf myhostname = sample.test.com ← 设置系统的主机名 mydomain = test.com ← 设置域名（我们将让此处设置将成为E-mail地址“@”后面的部分） myorigin = $mydomain ← 将发信地址“@”后面的部分设置为域名（非系统主机名） inet_interfaces = all ← 接受来自所有网络的请求 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain ← 指定发给本地邮件的域名 home_mailbox = Maildir/ ← 指定用户邮箱目录
然后测试邮件
echo "Mail Content" | mail -s "Mail Subject" xxxx@xxx.com
若出现【-bash: mail: command not found】执行如下命令：
yum -y install mailx
Note:if you see below warings after you run above command.
send-mail: warning: inet_protocols: IPv6 support is disabled: Address family not supported by protocol
send-mail: warning: inet_protocols: configuring for IPv4 support only
postdrop: warning: inet_protocols: IPv6 support is disabled: Address family not supported by protocol
postdrop: warning: inet_protocols: configuring for IPv4 support onlythat means you don't have IPv6 configured in your OS's network stack, but your mailer (presumably postfix) is configured to use IPv6. Since there is no IPv6 for your mailer to use, it's warning you that it's only going to use IPv4.
To disable the waring messsage, Go to /etc/postfix/main.cf and change from:
inet_protocols = all
to:
inet_protocols = ipv4
This will only use ipv4 and the warning message will go away.
You will have to issue a stop and start for postfix to register the change.
service postfix restart
查看log，确认邮件发送状态
Postfix邮件的log位置是：/var/log/maillog
发送成功的话，会返回250和OK，也可以去自己的邮件客户端查收。
一切OK的话，那Postfix mail service应该就搭建成功了。
查看邮件队列
postqueue -p
2. Add the GitLab package server and install the package
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash sudo yum install gitlab-ce
这里因为网络院线可能会出现下载失败，我尝试了两次后成功了。
3. Configure and start GitLab
sudo gitlab-ctl reconfigure
troubleshooting：
【Error executing action `run` on resource 'execute[semodule -i /opt/gitlab/embedded/selinux/rhel/7/g】
yum install libsemanage-static libsemanage-devel
解决Gitlab的Gravatar头像无法显示的问题
vim /etc/gitlab/gitlab.rb #把下面这一行的注释去掉即可 gitlab_rails['gravatar_plain_url'] = 'http://www.gravatar.com/avatar/%{hash}?s=%{size}&d=identicon'
编辑完gitlab.rb文件后要执行sudo gitlab-ctl reconfigure
解决邮件中URL指向问题
vim /etc/gitlab/gitlab.rb #将localhost修改为你对应的iP或者域名 external_url 'http://101.101.101.80'
同上，编辑完gitlab.rb文件后要执行sudo gitlab-ctl reconfigure
希望以上笔记能帮助你理解gitlab的官方文档。
