CentOs7搭建gitLab

yum install -y curl policycoreutils-python openssh-server
systemctl enable sshd
systemctl start sshd
firewall-cmd --permanent --add-service=http
systemctl reload firewalld

注：对于防火墙直接关闭内网防火墙即可，服务器内存至少4G

yum install postfix
systemctl enable postfix
systemctl start postfix

错误： Job for postfix.service failed because the control process exited with error code. See "systemctl st 
解决：修改 /etc/postfix/main.cf的设置  
inet_protocols = ipv4  
inet_interfaces = all 

下载最新rpm安装：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7
rpm -i gitlab-ce-10.6.4-ce.0.el7.x86_64.rpm #安装

或镜像安装：
curl -sS http://packages.gitlab.com.cn/install/gitlab-ce/script.rpm.sh | sudo bash
yum install gitlab-ce

external_url ‘http://gitlab.mag998.com/‘ #需添加域名解析

gitlab-ctl reconfigure #重置初始化
gitlab-ctl restart #启动

报错ENOMEM：内存至少4G，500等错误，增加内存
free -m #查看swap分区大小
mkdir /swapfile
cd /swapfile
sudo dd if=/dev/zero of=swap bs=1024 count=5000000 #修改count，5G的大小
mkswap -f  swap #转化为swap文件
swapon swap #激活swap文件
free -m #查看大小
swapoff swap #卸载swap分区
/swapfile/swapfile none swap defaults 0 0  #写入/etc/fstab文件

访问报错502：chmod -R 755 /var/log/gitlab

注：关闭原有nginx和tomcat,因为他们会占用80，8080端口，加swap分区后最好重启服务器

1. /etc/gitlab/gitlab.rb文件
unicorn[‘port‘] = 8081
nginx[‘listen_port‘] = 82
gitlab_rails[‘smtp_enable‘] = false #postfix和smtp只能用一个

2. /var/opt/gitlab/gitlab-rails/etc/unicorn.rb文件
listen "127.0.0.1:8081", :tcp_nopush => true

3. /var/opt/gitlab/nginx/conf/gitlab-http.conf文件
listen *:82;

4. /var/opt/gitlab/gitlab-shell/config.yml文件
gitlab_url: "http://127.0.0.1:8081"

5. 重置/重启
gitlab-ctl reconfigure
gitlab-ctl restart
