supervisor 文檔

supervisor 是用 Python 開發的一個 C/S 服務。是 Linux/Unix 系統下的進程管理工具。它能夠很方便的監聽、啓動、中止、重啓一個或多個進程。用Supervisor管理的進程，當一個進程意外被殺死，supervisort監聽到進程死後，會自動將它從新拉起，很方便的作到進程自動恢復的功能，再也不須要本身寫shell腳原本控制。

安裝

pip 方式

pip install supervisor

yum 方式

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum install supervisor -y

配置文件

pip 安裝的需自行生成配置文件

echo_supervisord_conf > /etc/supervisord.conf

cat /etc/supervisord.conf

[unix_http_server]
file=/opt/supervisor.sock   ; supervisorctl 使用的 socket 文件
chmod=0700                 ; socket 文件權限
;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]         ; web 管理界面，即在頁面作重啓、中止等操做
port=*:9001                ; 監聽端口

[supervisorctl]
serverurl=unix:///opt/supervisor.sock ; use a unix:// URL  for a unix socket
;serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket

;prompt=mysupervisor         ; cmd line prompt (default "supervisor")
;history_file=~/.sc_history  ; use readline history if available
