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

配置include路径

[include]

files = /etc/supervisor/conf.d/*.conf

注意事项

注意Supervisor只能管理非daemon的进程，所以tomcat 要以catalina.sh run前台方式执行。

添加进程管理

创建进程管理文件，并放入conf.d

如下

进程管理文件如下：

[program:onehee-tomcat]

command=/opt/soft/apache-tomcat/bin/catalina.sh run

directory=/opt/soft/apache-tomcat/bin/

autorestart=true

user=root

autostart=true

stdout_logfile=/opt/soft/apache-tomcat/logs/catalina.out

redirect_stderr=true

stdout_logfile_maxbytes=100MB

stdout_logfile_backups=10

开机启动supervisor

把supervisord 文件(见附录文档)放在 /etc/init.d/

在supervisord中需要修改一下JAVA 路径（默认/usr/java/ jdk1.7.0_79/bin）即可
