一、安装git
# yum –y install git
#创建用户，如果创建过git又删除，则再创建时，需要指定用户组useradd git -g git
# useradd git
# passwd git
# 授权（gogs的目录，gogs仓库的目录）
# chown -R git:git [gogs的目录]
# chown -R git:git [gogs仓库的目录]
如果提示系统运行用户: git -> root，则在安装页面中，将运行用户由git改为root
# 注意：以下红色不要执行，因为gogs指定git用户运行的话，要求git必须能登录
# 禁用git用户shell登录
# vi /etc/passwd
#找到git用户对应的行，将/usr/bin/bash 改为 /usr/bin/git-shell
二、安装gogs
# 上传gogs压缩包到/opt
# 解压后，进入gogs目录下，执行./gogs web
# 浏览器中访问ip:3000，首次访问会有安装向导（只能安装一次，如果想重装，可以删除掉目录再重新解压，所以仓库最好单独指定），管理员不能用admin。
# 安装完成后，会自动跳转到配置的域名/user/login页面，默认域名为localhost
配置文件路径
Custom config '/opt/gogs/custom/conf/app.ini' not found, ignore this if you're running first time
#防火墙开放3000端口
如果遇到问题:
数据库设置不正确：Error 1071: Specified key was too long; max key length is 767 bytes
ElasicSearch关联的mysql表，插入数据时会有以下提示
ERROR 1071 (42000): Specified key was too long; max key length is 767 bytes
原因分析：
MySQL的varchar主键只支持不超过767个字节,需要将mysql的字符编码设置为utf8mb4
输入以下命令打开编辑界面
- sudo vi /etc/mysql/my.cnf
在[mysqld]下加入以下配置：
- innodb_file_format=barracuda
- innodb_file_per_table=true
- innodb_large_prefix=true
- character-set-server=utf8mb4
- collation-server=utf8mb4_unicode_ci
- max_allowed_packet=500M
保存完重启后就能插入了。
注意：以上设置在重启mysql后，还需要修改表的row_format
altertable <table_name> row_format=dynamic;
altertable <table_name> row_format=compressed;
使用命令修改配置，有些配置无法用命令修改
show variables like 'innodb_large%';
set global innodb_large_prefix=1;
# 备份（仓库和关联的数据库）
# ./gogs backup
#恢复，--from="备份文件名称（默认备份路径为gogs根目录）"
# ./gogs restore --from="backup_name"
设置开机启动
将gogs/scripts/systemd/gogs.service拷贝到/usr/lib/systemd/system，然后使用命令设置开机启动，如果启动不成功，则需要修改gogs.service中的WorkingDirectory ExecStart 和 HOME 后面的路径。
# cp /opt/gogs/scripts/systemd/gogs.service /lib/systemd/system
# systemctl enable gogs.service
# systemctl start gogs.service
# systemctl status gogs.service
以上方案重启失败，查询官方GIT，发现有新的脚本，使用新的配置文件，重启时可以实现开机启动，断电后开机则不行，查看系统日志（/var/log/messages），发现gogs在MYSQL之前启动，修改gogs.service，添加mysql依赖After=mysql.service
gogs.service内容：
[Unit]
Description=Gogs
After=syslog.target
After=network.target
After=mariadb.service mysql.service mysqld.service postgresql.service memcached.service redis.service
[Service]

# repos with lots of files and get an HTTP error 500 because
# of that
