Ubuntu 下使 supervisord 随系统启动 (sysV init.d) --- Obsoleted

===================================================================================================================  Obsoleted 

从 https://github.com/Supervisor/initscripts 下载 initscript，注意根据当前机器 supervisor 的安装情况和 supervisor.conf 的配置情况调整 ubuntu initscript。

 

例如，我的 supervisord 和 supervisorctrl 分别为，

$ which supervisord 
/usr/local/bin/supervisord
$ which supervisorctl 
/usr/local/bin/supervisorctl

则调整 initscript 如下，

...
. /lib/lsb/init-functions

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/local/bin/supervisord
SUPERVISORCTL=/usr/local/bin/supervisorctl
NAME=supervisord
DESC=supervisor

test -x $DAEMON || exit 0
...

我的 supervisord.conf 在 /etc 目录下，并且其中配置的 logfile 和 pid 都在 /tmp 下 (因为有些系统会周期性的删除 /tmp 下的旧文件，所以不建议将 logfile 和 pid 文件存在此目录下)，所以调整 initscript 如下，

...
test -x $DAEMON || exit 0
LOGDIR=/var/log
PIDFILE=/var/run/$NAME.pid

DODTIME=5                   # Time to wait for the server to die, in seconds
                            # If this value is set too low you might not
                            # let some servers to die gracefully and
                            # 'restart' will not work

# Include supervisor defaults if available
if [ -f /etc/default/supervisor ] ; then
    . /etc/default/supervisor
fi
DAEMON_OPTS="-c /etc/supervisord.conf $DAEMON_OPTS"

set -e

running_pid()
...

调整 /etc/supervisord.conf，

...
[unix_http_server]
file=/var/run/supervisor.sock   ; the path to the socket file
chmod=0777;                     ; socket file mode (default 0700)
...
[supervisord]
logfile=/var/log/supervisord.log ; main log file; default $CWD/supervisord.log
...
pidfile=/var/run/supervisord.pid ; supervisord pidfile; default supervisord.pid
...
[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket
...

然后将调整后的 initscript 文件拷贝到 /etc/init.d 目录下，并重命名为 supervisord

$ sudo cp ubuntu /etc/init.d/supervisord

然后，为其增加可执行权限，

$ sudo chmod a+x /etc/init.d/supervisord

 然后，schedule it，

$ sudo update-rc.d supervisord defaults

然后，重新启动服务，

$ sudo service supervisord stop
$ sudo service supervisord start

 

当 /etc/init.d/supervisord 配置有改变时，需要首先，

$ sudo systemctl daemon-reload

然后再重启服务，

$ sudo service supervisord stop
$ sudo service supervisord start
