1、官方文档：

数据库准备 | Gitea Documentation

使用二进制文件安装 | Gitea Documentation

2、具体操作

1）创建gitea数据库

2）检查是否安装 Git。要求 Git 版本 >= 2.0。

如需升级git请参考以下链接：linux升级git版本-CSDN博客

[root@localhost root]# git --version
git version 2.31.0

3）创建git用户：（我本机系统 CentOS，即取下方代码）

# On Ubuntu/Debian:
adduser \--system \--shell /bin/bash \--gecos 'Git Version Control' \--group \--disabled-password \--home /home/git \git# On Fedora/RHEL/CentOS:
groupadd --system git
adduser \--system \--shell /bin/bash \--comment 'Git Version Control' \--gid git \--home-dir /home/git \--create-home \git

4）创建gitea目录，在此目录（ /var/lib/gitea ）下下载gitea 可执行文件

[root@localhost root]# 
mkdir -p /var/lib/gitea/custom
mkdir -p /var/lib/gitea/data
mkdir -p /var/lib/gitea/log
chown -R git:git /var/lib/gitea/
chmod -R 770 /var/lib/gitea/[root@localhost root]# cd /var/lib/gitea/
[root@localhost gitea]# wget -O gitea https://dl.gitea.com/gitea/1.21.1/gitea-1.21.1-linux-amd64
[root@localhost gitea]# chmod +x gitea[root@localhost gitea]# ll
总用量 139980
drwxr-x---  3 git git        18 12月 20 14:09 custom
drwxr-x--- 17 git git       257 12月 20 14:10 data
-rwxr-x---  1 git git 143338448 12月 20 13:57 gitea （此为gitea可执行文件）
drwxrwxr-x  2 git git         6 12月 20 13:10 lfs
drwxr-x---  2 git git         6 12月 20 12:08 log

4)  切换到gitea用户，运行gitea可执行文件，生成gitea数据库的数据表，在浏览器执行 http://127.0.0.1:3000 配置gitea仓库所需信息

[root@localhost root]# su git[git@localhost gitea]# ./gitea

5）配置service 自动启动gitea

在 Linux 中以 service 方式运行 | Gitea Documentation

5.1）错误界面

5.2）配置自启动

服务器重启后，再访问gitea网址，若出现5.1中的错误界面，大概率是未配置服务器自启动导致，具体配置参数如下：
