Frappe多Bench环境Supervisor配置异常：调度器与Worker故障

环境背景 #

• CentOS专属服务器，root用户安装Frappe bench CLI
• 服务器存在多个Linux用户，每个用户对应独立域名/子域名
• 各用户拥有独立Bench与站点，已手动配置NGINX和Redis，所有站点可正常访问

问题现象 #

仅首个部署的站点的调度器、后台Worker可正常运行，其余站点的相关组件故障，Supervisor报错如下：

配置对比 #

正常站点的supervisor.conf中bench路径配置正确：

[program:frappe-bench-frappe-schedule]
command=/usr/local/bin/bench schedule
priority=3
autostart=true
autorestart=true
stdout_logfile=/home/t2/frappe-bench/logs/schedule.log
stderr_logfile=/home/t2/frappe-bench/logs/schedule.error.log
user=t2
directory=/home/t2/frappe-bench

[program:frappe-bench-frappe-default-worker]
command=/usr/local/bin/bench worker --queue default
priority=4
autostart=true

异常站点的配置中command字段被设为None，手动修改后执行bench setup supervisor无法解决问题。

解决步骤 #

1. 切换到目标用户环境 #

必须以对应站点的Linux用户身份操作，避免root权限导致的路径或权限问题：

su - [目标用户名]
cd ~/frappe-bench

2. 验证Bench命令路径 #

确认当前用户能正确识别bench命令：

which bench

如果输出不是/usr/local/bin/bench，将bench路径添加到用户的环境变量中：

echo 'export PATH=$PATH:/usr/local/bin' >> ~/.bashrc
source ~/.bashrc

3. 生成用户专属Supervisor配置 #

以目标用户身份执行，跳过已手动配置的Redis：

bench setup supervisor --skip-redis --user [目标用户名]

4. 更新Supervisor配置并重启 #

将生成的配置链接到Supervisor配置目录，然后重载配置并重启服务：

sudo ln -s ~/frappe-bench/config/supervisor.conf /etc/supervisor/conf.d/frappe-bench-[用户名].conf
sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl restart all

5. 验证修复结果 #

查看Supervisor状态确认组件运行正常：

supervisorctl status
