解决，下载 libmysqlclient.so.18 文件
网上可用的链接下载 （亲测可用）
http://files.directadmin.com/services/es_7.0_64/libmysqlclient.so.18
并创建软链接
[root@linux-node2~]# ln -s /root/libmysqlclient.so.18 /usr/lib64/libmysqlclient.so.18

添加GitLab软件包仓库
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
The repository is setup! You can now install packages.
安装GitLab
[root@linux-node2~]# sudo EXTERNAL_URL=“你的公网IP地址” yum install -y gitlab-ce
可以看下gitlab-ee包的内容，看到gitlab安装在/opt/gitlab目录下
[root@linux-node2~]# rpm -ql gitlab-ee | less
修改gitlab内置的nginx 对外的监听的端口，默认80
vim /etc/gitlab/gitlab.rb
##! **Override only if you use a reverse proxy**
##! Docs: https://docs.gitlab.com/omnibus/settings/nginx.html#setting-the-nginx-listen-port
nginx['listen_port'] = 8883
重新配置：
gitlab-ctl reconfigure
重启服务：
gitlab-ctl restart
首次访问要修改root 用户的密码：
gitlab 内置nginx配置文件位置
/var/opt/gitlab/nginx目录
/var/opt/gitlab/nginx/conf/nginx.conf
access_log /var/log/gitlab/nginx/gitlab_access.log gitlab_access;
error_log /var/log/gitlab/nginx/gitlab_error.log;
include /var/opt/gitlab/nginx/conf/gitlab-http.conf;
include /var/opt/gitlab/nginx/conf/nginx-status.conf;
本次的安装 gitlab的安装搭建已完成！
gitlab官方是这样给的帮助步骤;
- Install and configure the necessary dependencies
On CentOS 7 (and RedHat/Oracle/Scientific Linux 7), the commands below will also open HTTP, HTTPS and SSH access in the system firewall.
sudo yum install -y curl policycoreutils-python openssh-server
sudo systemctl enable sshd
sudo systemctl start sshd
sudo firewall-cmd –permanent –add-service=http
sudo firewall-cmd –permanent –add-service=https
sudo systemctl reload firewalld
Next, install Postfix to send notification emails. If you want to use another solution to send emails please skip this step and configure an external SMTP server after GitLab has been installed.
sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix
During Postfix installation a configuration screen may appear. Select ‘Internet Site’ and press enter. Use your server’s external DNS for ‘mail name’ and press enter. If additional screens appear, continue to press enter to accept the defaults.
- Add the GitLab package repository and install the package
Add the GitLab package repository.
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | sudo bash
Next, install the GitLab package. Change https://gitlab.example.com to the URL at which you want to access your GitLab instance. Installation will automatically configure and start GitLab at that URL.
For https:// URLs GitLab will automatically request a certificate with Let’s Encrypt, which requires inbound HTTP access and a valid hostname. You can also use your own certificate or just use http://.
sudo EXTERNAL_URL=“https://gitlab.example.com” yum install -y gitlab-ee
3. Browse to the hostname and login
On your first visit, you’ll be redirected to a password reset screen. Provide the password for the initial administrator account and you will be redirected back to the login screen. Use the default account’s username root to login.
See our documentation for detailed instructions on installing and configuration.
- Set up your communication preferences
Visit our email subscription preference center to let us know when to communicate with you. We have an explicit email opt-in policy so you have complete control over what and how often we send you emails.
Twice a month, we send out the GitLab news you need to know, including new features, integrations, docs, and behind the scenes stories from our dev teams. For critical security updates related to bugs and system performance, sign up for our dedicated security newsletter.
Important note: If you do not opt-in to the security newsletter, you will not receive security alerts.
- Configure sign-up restrictions and sign-in preferences.
After completing your installation, consider the recommended practices to secure your GitLab instance.
Install or update a GitLab Package
After the GitLab package is downloaded, install it using the following commands:
For GitLab Community Edition:
# GitLab Community Edition
# Debian/Ubuntu
dpkg -i gitlab-ce-<version>.deb
# CentOS/RHEL
rpm -Uvh gitlab-ce-<version>.rpm
For GitLab Enterprise Edition:
# Debian/Ubuntu
dpkg -i gitlab-ee-<version>.deb
# CentOS/RHEL
rpm -Uvh gitlab-ee-<version>.rpm
Tip: If you are installing for the first time, you can pass the EXTERNAL_URL="<GitLab URL>" variable to set your preferred domain name. Installation will automatically configure and start GitLab at that URL. Enabling HTTPS requires additional configuration to specify the certificates.
Browse to the hostname and login
On your first visit, you’ll be redirected to a password reset screen. Provide the password for the initial administrator account and you will be redirected back to the login screen. Use the default account’s username root to login.
See our documentation for detailed instructions on installing and configuration.
