CentOS-7搭建Gitlab服务器

约定不等于承诺〃 2023-07-03 15:29 23阅读 0赞

由于疫情情况，我们需要在家办公，公司的git服务器搭建的是内网，现在在家了，所以需要搭建一个外网的git，保证大家在家就能访问，我是在我购买的阿里云的机器上搭建的，机器的配置如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70][]

登录gitlab官网 [https://about.gitlab.com/][https_about.gitlab.com]

选择Resources中的install GitLab

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 1][]

点击CentOS 7

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 2][]

[https://about.gitlab.com/install/\#centos-7][https_about.gitlab.com_install_centos-7]

可以看到如下内容

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 3][]

# #

## CentOS安装必要的依赖 ##

第一步：安装ssh

yum install -y curl policycoreutils-pythonopenssh-server

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 4][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 5][]

第二步： 将SSH服务设置成开机自启动并启动SSH服务（若安装并启动，则可跳过此步）；

sudo systemctl enable sshd
    sudo systemctl start sshd

![202002071519195.png][]

第三步：安装并启动防火墙（若安装并启动，则可跳过此步）；

yum install firewalld systemd -y
    service firewalld start

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 6][]

![20200207152302704.png][]

第四步：添加http服务到firewalld （--permanent表示永久生效）;

firewall-cmd --permanent --add-service=http

![2020020715242393.png][]

第五步：重启防火墙；

firewall-cmd --permanent --add-service=http

![20200207152525617.png][]

第六步：将postfix服务设置成开机自启动并启动postfix；

systemctl enable postfix
    systemctl start postfix

![20200207153716495.png][]

运行后，发现启动postfix没有成功，报了一行错误：

Job for postfix.service failed because the control process exited with error code. See "systemctl status postfix.service" and "journalctl -xe" for details.

这是因为防火墙或者配置文件导致，无法启动的邮件服务！！

解决方法如下：

1-关闭防火墙：systemctl stop firewalld

![20200207153919754.png][]

2-安装sendemail

yum -y install sendmail

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 7][]

3-修改配置文件

vim /etc/postfix/main.cf

修改内容如下：

inet_protocols = ipv4
    inet_interfaces = all

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 8][]

4-重新执行

systemctl enable postfix
    systemctl start postfix

![20200207154322198.png][]

第七步：检查系统中是否已经安装wget（若不存在，用yum安装wget）；

检查wget版本

wget -V

yum -y install wget

yum安装wget

yum -y install wget

# #

## 开始安装gitlab ##

按照官网的下载速度有点慢，就改变了一种方式：

第一步：wget下载gitlab

gitlab官网下载地址是：[https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/?C=M&O=D][https_mirrors.tuna.tsinghua.edu.cn_gitlab-ce_yum_el7_C_M_O_D]

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-12.7.5-ce.0.el7.x86_64.rpm

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 9][]

第二步：安装gitlab；

rpm -i gitlab-ce-12.7.5-ce.0.el7.x86_64.rpm

![20200207165201435.png][]

错误信息：

warning: gitlab-ce-12.7.5-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-12.7.5-ce.0.el7.x86_64

出现上面错误，需要安装 policycoreutils-python;

yum -y install policycoreutils-python

![20200207165527711.png][]

再次执行安装命令

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 10][]

第三步：修改gitlab配置文件，指定服务器ip和自定义端口；

vi /etc/gitlab/gitlab.rb

![202002071658161.png][]

![20200207165824793.png][]

修改external\_url

external_url 'http://47.96.100.144:8081'

![20200207170012303.png][]

修改端口

修改前：

![20200207170135990.png][]

修改后：

![20200207170222656.png][]

修改unicorn的配置

![20200207170443833.png][]

第四步：重置并启动GitLab；

重置gitlab配置命令：

gitlab-ctl reconfigure

我的机器运行改命令花费了7分多钟

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 11][]

重启gitlab服务

gitlab-ctl restart

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 12][]

第五步：访问Gitlab

若无法访问，则可以查看端口是否被禁用；

1、查看端口状态：

netstat -lntp

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 13][]

有端口，但是访问不同，重新开放下端口试试

2、防火墙开放端口：

firewall-cmd --zone=public --add-port=8081/tcp --permanent

![20200207172054761.png][]

提示如下：

FirewallD is not running

有可能防火墙挂了，使用命令查看防火墙状态

systemctl status firewalld

发现防火前active是dead

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 14][]

通过systemctl start firewalld开启防火墙，没有任何提示即开启成功。

systemctl start firewalld

再次查看防火墙状态发现已经是running状态

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 15][]

再次开放防火墙8081端口

![20200207172809273.png][]

成功

重新加载防火墙列表

firewall-cmd --reload

![20200207172857349.png][]

再次访问还是不行，忽然想到我是使用的阿里云的云服务器，需要配置安全组才可以

![20200207173213646.png][]

可以访问了，不过是502

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTExNTk0MTc_size_16_color_FFFFFF_t_70 16][]

页面错误信息如下：

# 502 #

### Whoops, GitLab is taking too much time to respond. ###

可以导致这个问题的原因有很多，

比如：

部分功能没有启动起来

这种情况可以使用`gitlab-ctl status`命令查看正在运行的进程的id。运行几次，如果有id改变了，则说明这个进程不稳定，需要查看对应的日志。

使用`gitlab-ctl tail [process name]`命令查看对应的进程是什么情况。如果是端口冲突，则解决端口冲突，如果是权限问题则解决权限问题。

我遇到的情况是：

1.  内存不足（最小2G）

网上反馈的是最小需要2G内存，弄了个虚拟机试了下，总共3G内存，勉强可以配置使用gitlab启动运行之后相当的消耗内存，尤其是做提交更新等处理的时候，出现这个错误的时候可以使用`free -m`查看下内存情况：

看下used和free的使用情况，如果free一直在减少，说明gitlab正在启动，消耗内存中，还没有启动完成！这个时候访问是会提示502 Whoops, GitLab is taking too much time to respond.

我的就属于内存不足的情况，大家如果搭建的时候，最好找一台内存大的机器
