用主管启动 redis

Question

当用supervisor启动redis时，redis进程正在运行，但是在supervisor中它显示退避。

vagrant@jinming:~$ sudo supervisorctl -c /etc/conf/supervisor/supervisord.conf
redis                            BACKOFF   Exited too quickly (process log may have details)

在主管日志中，显示如下：

2015-06-09 07:09:28,407 CRIT Supervisor running as root (no user in config file)

任何人都可以帮助我，谢谢。

当使用 Supervisord 管理服务器程序（如经常产生或守护进程的数据库）时，请在启动命令或配置文件中查找标志。像 MySQL 这样的数据库有一个例外，推荐的做法是使用代理启动 mysqld_safe 并让它管理子进程。

在redis.conf 中，对于较新的版本（即 3.x），默认是禁用守护程序，但它可能已被您的包编辑。还要确保您没有安装会重新生成的新贵脚本。

Redis 配置文件部分

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize no

问题

redis-server 不适用于下面的supervisord.conf

尤其是redis-server 带有 conf 文件位置参数的命令

redis-server --version

Redis server v=2.8.17 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=5b70b85861dcf95e

supervisord.conf

[program:redis-server]
command=redis-server /etc/redis/redis.conf # PLEASE NOTE THIS LINE
autostart=true
autorestart=true
user=root
stdout_logfile=/var/log/redis/stdout.log
stderr_logfile=/var/log/redis/stderr.log

my_redis.conf

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize no

Dockerfile

RUN cp -f my_redis.conf /etc/redis/redis.conf &&\

supervisorctl

通过命令行测试

解决方案

没有自定义 conf 文件位置，一切正常。

就我而言，我用my_redis.conf 覆盖了/etc/redis/redis.conf 中的默认配置

[program:redis-server]
command=redis-server # JUST REMOVE EXTRA CONF FILE LOCATION, EVERYTHING WORKS WELL
autostart=true
autorestart=true
user=root
stdout_logfile=/var/log/redis/stdout.log
stderr_logfile=/var/log/redis/stderr.log

ps。这个redis版本有bug吗？还是我的配置错了？
