# zcbot nginx 反代示例(蓝绿双实例,RUN.md §无感更新 B 档)。
|
|
#
|
|
# 端口约定:nginx 接管原单实例的对外端口 8765(客户端 / platform 嵌入 URL 不用改),
|
|
# 实例挪到本机 8766(blue)/ 8767(green)。装 nginx 前先停旧单实例服务释放 8765。
|
|
#
|
|
# 安装(一次性):
|
|
# sudo cp deploy/nginx/zcbot.conf.example /etc/nginx/conf.d/zcbot.conf # 按需改 server_name/TLS
|
|
# echo 'server 127.0.0.1:8766;' | sudo tee /etc/nginx/zcbot_upstream.conf # 初始指 blue
|
|
# sudo nginx -t && sudo systemctl reload nginx
|
|
#
|
|
# 之后 zcbot_upstream.conf 由 deploy/update_bluegreen.sh 改写 + reload nginx 切流量,
|
|
# 本文件不再动。nginx reload 对已建立连接零影响:旧 SSE 留在旧实例自然收尾,新请求走新实例。
|
|
|
|
