# setup-runner.sh —— 一键安装并注册 Gitea Actions Runner（act_runner）
|
||
#
|
||
# 使用方法：
|
||
# ① 先在你的 Gitea 仓库页面 → Settings → Actions → Runners → 「Create Runner」
|
||
# 选「Linux + amd64」，它会给你一条注册命令，里面有一串 registration token，
|
||
# 格式像： GFxxxxxxxxxxxxxxxxxxxx ，复制它。
|
||
# ② 再在你要跑 Runner 的机器上执行：
|
||
# curl -fsSL https://<你的-gitea>/<仓库>/-/raw/branch/main/scripts/setup-runner.sh \
|
||
# | sudo bash -s -- --gitea https://<你的-gitea> --token GFxxxxxxxxxxxxxxxxxxxx
|
||
#
|
||
# 或者直接本地执行：
|
||
# sudo bash scripts/setup-runner.sh \
|
||
# --gitea https://git.baoyiwai.com \
|
||
# --token GFxxxxxxxxxxxxxxxxxxxxxxxxxxxx
