supervisor管理tomcat

注意

在生产环境中是不允许以root用户运行tomcat的，我们是以一个有root权限的运维专用用户来运行supervisor和tomcat的

supervisor配置文件 /etc/supervisor/supervisord.conf 中定义了include，因此如果想要管理服务，就需要编辑 /etc/supervisor/config.d/*.ini 文件

[include] 
files = /etc/supervisor/config.d/*.ini

编辑tomcat服务配置文件 /etc/supervisor/config.d/tomcat.ini

• tomcat安装目录 /usr/local/tomcat-8.5.56/
• jdk1.8安装目录 /usr/local/jdk1.8.0_251/

[program:tomcat] 
command=/usr/local/tomcat-8.5.56/bin/startup.sh 
environment=JAVA_HOME="/usr/local/jdk1.8.0_251",JAVA_BIN="/usr/local/jdk1.8.0_251/bin"
autostart = true 
autorestart=true 
redirect_stderr=true 
stdout_logfile=/var/log/supervisor/tomcat.log

修改tomcat启动脚本文件 startup.sh

本文示例是 /usr/local/tomcat-8.5.56/bin/startup.sh

最后一行，将start修改为run
#exec "$PRGDIR"/"$EXECUTABLE" start "$@"
exec "$PRGDIR"/"$EXECUTABLE" run "$@"

用以下命令修改

sed -i.bak '$s/start/run/' startup.sh

将tomcat加入supervisor

$ supervisorctl update tomcat
tomcat: added process group

查看状态

$ supervisorctl status tomcat
nginx           RUNNING   pid 9464, uptime 0:00:03
