配置文件路径

1

配置文件内容

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
chmod=0700                       ; sockef file mode (default 0700)

[supervisord]
logfile=/var/log/supervisor/supervisord.log ;(main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ;(supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; ('AUTO' child log dir, default $TEMP)
logfile_maxbytes=50MB        ;日志文件大小，超出会rotate，默认 50MB，如果设成0，表示不限制大小
logfile_backups=10           ;日志文件保留备份数量默认10，设为0表示不备份
loglevel=info                ;日志级别，默认info，其它: debug,warn,trace
nodaemon=false               ;是否在前台启动，默认是false，即以 daemon 的方式启动
minfds=1024                  ;可以打开的文件描述符的最小值，默认 1024
minprocs=200                 ;可以打开的进程数的最小值，默认 200

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

[inet_http_server]
port=0.0.0.0:9001

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

2.2 将需要后台运行的程序挂载到配置文件

（此处是配置模板，请根据自己需求自行配置）

## 将需要挂载到后台运行的配置文件放置到 /etc/supervisord/conf.d/alter.conf
# 例如：altermanager
[program:alertmanager]
# 程序所在目录
directory = /opt/project/alertmanager/
# 启动程序的命令;
command = /opt/project/alertmanager/alertmanager --config.file=/opt/project/alertmanager/alertmanager.yml --cluster.advertise-address=0.0.0.0:9093
# 在supervisord启动的时候也自动启动;
autostart = true
# 程序异常退出后自动重启;
autorestart = true
# 启动5秒后没有异常退出，就当作已经正常启动了;
startsecs = 5
# 启动失败自动重试次数，默认是3;
startretries = 3
# 启动程序的用户;
user = root
# 把stderr重定向到stdout，默认false;
redirect_stderr = true
# 标准日志输出;
stdout_logfile=/tmp/alertmanager_stdout.log
# 错误日志输出;
stderr_logfile=/tmp/alertmanager_stderr.log
# 标准日志文件大小，默认50MB;
stdout_logfile_maxbytes = 20MB
# 标准日志文件备份数;
stdout_logfile_backups = 20
