Python中如何配置supervisor进行进程管理

得重启 supervisor 服务…

要配置supervisor管理Python进程，先安装：pip install supervisor。然后生成默认配置：echo_supervisord_conf > /etc/supervisord.conf（Linux）或输出到当前目录。

关键是在配置里添加你的程序。打开配置文件，在底部添加：

[program:myapp]
command=/path/to/your/python /path/to/your/script.py
directory=/path/to/your/app
autostart=true
autorestart=true
user=yourusername
stdout_logfile=/var/log/myapp.log
stderr_logfile=/var/log/myapp_err.log

参数说明：command是启动命令，directory设置工作目录，autostart让supervisor启动时自动运行它，autorestart会在进程退出时自动重启，user指定运行用户，stdout_logfile和stderr_logfile分别记录标准输出和错误日志。

启动supervisor：supervisord -c /path/to/supervisord.conf。管理命令：supervisorctl status查看状态，supervisorctl restart myapp重启你的应用，supervisorctl stop myapp停止。

用supervisor能确保进程持续运行，挂了自动重启，还能方便地查看日志和管理。

下面是 supervisor.conf 和 elasticsearch.conf 的配置内容。

supervisor.conf:

[include]
files = /etc/supervisord/conf.d/elasticsearch.conf

elasticsearch.conf:

[program=sticsearch]
command=systemctl restart elasticsearch.service
;command=/usr/share/elasticsearch/bin/elasticsearch
;directory=/usr/share/elasticsearch
autostart=true
autorestart=true

stderr_logfile=/home/public/log/elasticsearch/elasticsearch-stderr.log

主配置里面默认会包含所有 conf.d 下面的 conf 后缀文件回头我看看我的配置

bupafengyu 5楼

我安装完 supervisor 后，在 etc 下面没有 /etc/supervisord 文件夹的，我是自己创建的 /etc/supervisord/con.d/文件夹，然后把 elasticsearch.conf 放在里面。

vueper 6楼

恩看起来没啥错，我的 centos6.8 安装后，主文件是包括如下两行

[include]
files = /etc/supervisor.d/*.conf

你的配置看起来也没啥问题的，要不试试
ls /etc/supervisord/conf.d/elasticsearch.conf
看看这个文件是不是真正的存在呢？不存在的概率可能比较小，不过工作中经常会遇到这种情况，呵呵。

phonegap100 7楼

文件是存在的。郁闷。。一直找不到原因。

vueper 8楼

既然文件已经加载了，怀疑还是配置的问题，
1. 是不是配置的 program 名字有冲突？
2. 打开界面，可能更一目了然

在 supervisord.conf 开头加上或者修改如下，打开 http ，一目了然

[unix_http_server]
file=/tmp/supervisor.sock ; (the path to the socket file)
[inet_http_server] ; inet (TCP) server disabled by default
port=0.0.0.0:1009 ; (ip_address:port specifier, *:port for all iface)
username=ops ; (default is no username (open server))
password=123123 ; (default is no password (open server))

yibo5220 9楼

我大概知道了， supervisor 在执行命令的时候要求比较苛刻，比如全路径呀，环境变量报错呀啥的，刚刚的 http 页面可以让你看到
1. elasticsearch 进程是否配置到 supervisord
2. 启动情况如何，是 ok 还是 fail
3. 瞅瞅 log 里面有啥吧

sinazl 10楼

supervisord.conf 用的是默认设置，我没修过过。

[unix_http_server]
file=/tmp/supervisor.sock ; (the path to the socket file)
chmod=0777 ; socket file mode (default 0700)
;chown=nobody:nogroup ; socket file uid:gid owner
;username=user ; (default is no username (open server))
;password=123 ; (default is no password (open server))

;[inet_http_server] ; inet (TCP) server disabled by default
;port=127.0.0.1:9001 ; (ip_address:port specifier, *:port for all iface)
;username=user ; (default is no username (open server))
;password=123 ; (default is no password (open server))

supervisord.log

貌似没看出有啥问题呢。也没有报错。

sinazl 11楼

Included extra file “/etc/supervisord/conf.d/elasticsearch.conf” during parsing

上面的一行说明你的 elasticsearch.conf 已经被加载了，现在我越来越猜测是 elasticsearch.conf 配置问题导致没有启动

既然没有打开 http ，那就使用如下命令看看 status 吧

supervisorctl status

yuanlaile 12楼

1.supervisor 配置中的 command 一定要处于挂起运行，把标准输出，是他的子进程，运行期间不能返回
2.你需要用命令行启动 es 的方式，配置到 command
3.既然用 systemd 和 supervisor 用一个就可以，他们都是守护

zlyuanteng 13楼

这样写试试 [program:sticsearch]

zlyuanteng 14楼

新版本先要启动 supervisord 然后在启动 supervisorctl ，不然会一直报错……

zlyuanteng 15楼

而且你 command 那里最好写成 shell 脚本去执行，错误概率小一点

sinazl 16楼

已经启动过了。 command 我用 /usr/share/elasticsearch/bin/elasticsearch 也是不能用的。在日志里面也看不到错误提示呢。

h691938207 17楼

，你看的什么错误日志，是 supervisor 的？还是 supervisor 配置文件中 es 的？这个启动不了应该是环境问题，一般是 java 环境， supervisor 自己的错误日志中应该有信息才对

itying888 18楼

是 supervisord.log

wuwangju 19楼

[program=sticsearch]

改为

这两个 log 呢？有错误信息

stderr_logfile=/home/public/log/elasticsearch/elasticsearch-stderr.log

先按照上面说的把配置写对 [program:sticsearch]

elasticsearch-stderr.log 内容为空。

我在重启 supervisor 后，进入 supervisorctl ，提示“ elasticsearch FATAL Exited too quickly (process log may have details)”

bupafengyu 23楼

elasticsearch 安装后，在 /usr/share/elasticsearch/就没有 config 这个文件的。

gougou168 24楼

你命令行成功启动过 es 么？
2.如果你只是在 systemd 中成功启动过，你的配置文件应该在系统级的目录下，找到他，先用命令行能启动，再把命令配置进去， es 在命令行可以指定配置文件的

itying888 25楼

ES 是可以正常启动和关闭的。我再看看这个错误提示到底是咋回事。。

wuwangju 26楼

我试试用命令行启动下。

phonegap100 27楼

配置文件改成这样的：

[program:elasticsearch]
command=/etc/init.d/elasticsearch start
directory=/usr/share/elasticsearch
autostart=true
autorestart=true
startsecs=10
startretries=3
redirect_stderr=true
user=root
stdout_logfile=/home/demoer/log/elasticsearch/elasticsearch-stdout.log
stderr_logfile=/home/demoer/log/elasticsearch/elasticsearch-stderr.log

我手动关闭 es 后，等了几秒钟 es 没有启动，就使用 supervisorctl restart elasticsearch 启动，
elasticsearch: ERROR (not running)
elasticsearch: ERROR (spawn error)

得到这样的错误提示，但是 es 却重新启动了。不能自动启动 es 呢。。

eggper 28楼

stop es 后，我目前的配置，只能手动执行 supervisorctl reload ，才能再让 es 启动。

songsunli 29楼作者

上面我指出过 supervisor 中 command 不能使用 systemctl 或者 init.d 的方式，因为这两种是 daemon 运行，命令执行完就返回了
2. 你加我上面的发群我用 qq 跟你说，这样解释太慢了，非商业化的群，不用担心
