主要是安装这些东西：Git、MySQL、Gogs
MySQL安装可以参考https://www.cnblogs.com/levia/p/11396512.html
这里记录我我执行过的命令（随意记录的可能没什么参考价值）
yum -y install git
git --version
rpm -qa|grep -i mysql
rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64
rpm -qa|grep mariadb
reboot
mkdir /usr/local/mysql8
cd /usr/local/mysql8
cat /etc/redhat-release
wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.25-1.el7.x86_64.rpm-bundle.tar
tar -xvf mysql-8.0.25-1.el7.x86_64.rpm-bundle.tar
rpm -ivh mysql-community-common-8.0.25-1.el7.x86_64.rpm
yum list mysql-community-client-plugins
rpm -ivh mysql-community-client-plugins-8.0.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-8.0.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-8.0.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.25-1.el7.x86_64.rpm
rpm -ivh mysql-community-embedded-compat-8.0.25-1.el7.x86_64.rpm
systemctl status mysqld
systemctl start mysqld
grep -i password /var/log/mysqld.log
net start mysql
mysql -u root -p 'mysql'
systemctl stop firewalld.service
systemctl disable firewalld.service
cd ../
tar -zxvf gogs_0.12.3_linux_amd64.tar.gz
cd gogs
cd var
cd /
mv /usr/local/gogs /home/git/
cp /home/git/gogs/scripts/systemd/gogs.service /etc/systemd/system/
./gogs web
sudo systemctl start gogs.service
sudo systemctl enable gogs.service
systemctl reload gogs.service
systemctl restart gogs.service
gogs.service

安装完成之后如果没改过端口，访问3000即可看到gogs的页面。
