2下载supervisor , 升级安装
https://github.com/Supervisor/supervisor/releases
2.1文件上传到/usr/local/src
我这里下载的是supervisor-3.4.0.tar.gz 因为系统的python是2.7.5 怕更高了需要3.0支持
https://github.com/Supervisor/supervisor/releases/tag/3.4.0
2.2 命令手动安装
cd /usr/local/src
tar -zxvf supervisor-3.4.0.tar.gz
cd supervisor-3.4.0
python setup.py installInstalled /usr/lib/python2.7/site-packages/supervisor-3.4.0-py2.7.egg
Traceback (most recent call last):

TypeError: __init__() takes exactly 2 arguments (4 given)看到成功的安装提示 Installed /usr/lib/python2.7/site-packages/supervisor-3.4.0-py2.7.egg
但是有个报错, 怀疑是之前安装了版本的问题, 试试可用不
2.3 测试
supervisorctl status
提示没有配置文件,应该是正常的 我们先加配置文件
如果发现报错
error: <class 'socket.error'>, [Errno 113] No route to host: file: /usr/lib64/python2.7/socket.py line: 571
先yum安装一下老版本
之后就是
unix:///var/run/supervisor/supervisor.sock no such file
3配置
命令查看 /etc/supervisord.conf 这个文件
最结尾看到
[include]
files = supervisord.d/*.ini
所以只要是/etc/supervisord.d/下面的所有ini文件 都会被加载 .
有些作者会让新建/etc/supervisord目录,或者配置文件后缀是.conf 其实都要看软件版本,不能一概而论.
如果是dotnet网站先/etc/supervisord.d下建立一个dotnet.ini
[program:dotnet]
command=dotnet InterfaceWeb.dll
directory=/www/wwwroot/myweb/
environment=ASPNETCORE__ENVIRONMENT=Production
user=root
stopsignal=INT
autostart=true
autorestart=true
startsecs=1
stderr_logfile=/www/wwwroot/dotnet.err.log
stdout_logfile=/www/wwwroot/dotnet.out.log
注意这里的路径都要存在stderr_logfile 和 stdout_logfile .具体每个参数代表什么意思,应该也很容易理解, 我不用中文注释了,怕格式问题,导致加载失败.
如果是Redis等其他服务 配置基本类似.
[program:redis]
command=/usr/bin/redis-server /usr/local/redis/redis.conf
autorstart=true
autorestart=true
stdout_logfile=/tmp/supervisor.log[program:usercenter]
directory = /home/leon/projects/usercenter ; 程序的启动目录
command = gunicorn -c gunicorn.py wsgi:app ; 启动命令，可以看出与手动在命令行启动的命令是一样的
autostart = true ; 在 supervisord 启动的时候也自动启动
startsecs = 5 ; 启动 5 秒后没有异常退出，就当作已经正常启动了
autorestart = true ; 程序异常退出后自动重启
startretries = 3 ; 启动失败自动重试次数，默认是 3
user = leon ; 用哪个用户启动
redirect_stderr = true ; 把 stderr 重定向到 stdout，默认 false
stdout_logfile_maxbytes = 20MB ; stdout 日志文件大小，默认 50MB
stdout_logfile_backups = 20 ; stdout 日志文件备份数
; stdout 日志文件，需要注意当指定目录不存在时无法正常启动，所以需要手动创建目录（supervisord 会自动创建日志文件）
stdout_logfile = /data/logs/usercenter_stdout.log
; 可以通过 environment 来添加需要的环境变量，一种常见的用法是修改 PYTHONPATH
; environment=PYTHONPATH=$PYTHONPATH:/path/to/somewhere4 启动并设置开机启动
supervisord -c /etc/supervisord.conf #启动服务
systemctl enable supervisord #开机启动
systemctl is-enabled supervisord #验证是否开机启动
supervisord -c /etc/supervisord.conf #启动服务
supervisorctl shutdown #关闭
supervisorctl status：查看所有进程的状态
supervisorctl stop dotnet：停止dotnet
supervisorctl start dotnet：启动dotnet
supervisorctl restart dotnet: 重启dotnet
supervisorctl update ：配置文件修改后可以使用该命令加载新的配置
supervisorctl reload: 重新启动配置中的所有程序
systemctl enable supervisord #开机启动
systemctl is-enabled supervisord #验证是否开机启动查看状态supervisorctl status .看到如下 表示已经成功运行了
如果看到的是这样的错误
dotnet FATAL Exited too quickly (process log may have details)
检查 ini文件的路径 .
检查启动命令
检查完成后用下面的kill 干掉进程,重新执行supervisord -c /etc/supervisord.conf
5 可能存在的问题
这个是因为端口被占用 干掉进程 重新启动就行
查看 ps -aux|grep supervisord
kill *****
DeprecationWarning: Parameters to load are deprecated. Call .resolve and .require separately.
return pkg_resources.EntryPoint.parse("x="+spec).load(False)这个是因为log文件问题, 大概率是因为版本过低,不支持stdout_logfile参数. 要保留这个就需要升级, 不需要就注释这个配置行就行
6 关于网站控制进程
解开这个配置 /etc/supervisord.conf , 然后设置端口和账号密码
如果还不能访问, 检查一下端口是否被禁止了.
[inet_http_server] ; inet (TCP) server disabled by default
port=*:19901 ; (ip_address:port specifier, *:port for all iface)
username=do***et ; (default is no username (open server))
password=2hj******33 ; (default is no password (open server))
查看端口 netstat -nltp | grep 19901
看看宝塔面板是否没有放行你使用的端口
检查云服务器后台的防火墙配置
浏览器地址访问:
http://IP.IP.IP.IP:19901输入配置的账号密码
username=do***et ; (default is no username (open server))
password=2hj******33 ; (default is no password (open server))
7 卸载
yum uninstall supervisor 等等
8 其他报错
# supervisorctl reload
error: <class 'socket.error'>, [Errno 2] No such file or directory: file: /usr/lib64/python2.7/socket.py line: 224
使用这样来启动
supervisord -c /etc/supervisord.conf
