如何获取supervisor的进程启动命令

以zookeeper为例，总结一下supervisor如何才能获取到监控进程的启动命令。

1. 先通过正常途径启动zookeeper

//守护启动的方式，supervisor是无法进行监控的。
[[email protected] bin]# /usr/local/zookeeper-3.4.10/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
           

2. 获取supervisor的启动命令

[[email protected] bin]# ps -ef | grep zookeeper
root     16053     1  0 10:24 pts/3    00:00:01 /usr/local/jdk8u212-b03/bin/java -Dzookeeper.log.dir=/usr/local/zookeeper-3.4.10/bin/../logs -Dzookeeper.root.logger=INFO,CONSOLE -cp /usr/local/zookeeper-3.4.10/bin/../build/classes:/usr/local/zookeeper-3.4.10/bin/../build/lib/*.jar:/usr/local/zookeeper-3.4.10/bin/../lib/slf4j-log4j12-1.6.1.jar:/usr/local/zookeeper-3.4.10/bin/../lib/slf4j-api-1.6.1.jar:/usr/local/zookeeper-3.4.10/bin/../lib/netty-3.10.5.Final.jar:/usr/local/zookeeper-3.4.10/bin/../lib/log4j-1.2.16.jar:/usr/local/zookeeper-3.4.10/bin/../lib/jline-0.9.94.jar:/usr/local/zookeeper-3.4.10/bin/../zookeeper-3.4.10.jar:/usr/local/zookeeper-3.4.10/bin/../src/java/lib/*.jar:/usr/local/zookeeper-3.4.10/bin/../conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg
root     16082  7954  0 10:32 pts/3    00:00:00  grep --color=auto zookeeper
           

获取到supervisor能监控的启动命令：/usr/local/jdk8u212-b03/bin/java -Dzookeeper.log.dir=/usr/local/zookeeper-3.4.10/bin/…/logs -Dzookeeper.root.logger=INFO,CONSOLE -cp /usr/local/zookeeper-3.4.10/bin/…/build/classes:/usr/local/zookeeper-3.4.10/bin/…/build/lib/.jar:/usr/local/zookeeper-3.4.10/bin/…/lib/slf4j-log4j12-1.6.1.jar:/usr/local/zookeeper-3.4.10/bin/…/lib/slf4j-api-1.6.1.jar:/usr/local/zookeeper-3.4.10/bin/…/lib/netty-3.10.5.Final.jar:/usr/local/zookeeper-3.4.10/bin/…/lib/log4j-1.2.16.jar:/usr/local/zookeeper-3.4.10/bin/…/lib/jline-0.9.94.jar:/usr/local/zookeeper-3.4.10/bin/…/zookeeper-3.4.10.jar:/usr/local/zookeeper-3.4.10/bin/…/src/java/lib/.jar:/usr/local/zookeeper-3.4.10/bin/…/conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /usr/local/zookeeper-3.4.10/bin/…/conf/zoo.cfg

3. 调试启动命令

有时候需要指定java的-classpath路径，先手动运行下看看能否正常运行。

[[email protected] bin]# /usr/local/jdk8u212-b03/bin/java -Dzookeeper.log.dir=/usr/loc 
al/zookeeper-3.4.10/bin/../logs -Dzookeeper.root.logger=INFO,CONSOLE -cp /usr/lo

验证没有问题。

4. 配置supervisor配置文件

[program:zookeeper] ;程序名称，终端控制时需要的标识
command=/usr/local/jdk8u212-b03/bin/java -Dzookeeper.log.dir=/usr/local/zookeeper-3.4.10/bin/../logs -Dzookeeper.root.logger=INFO,CONSOLE -cp /usr/local/zookeeper-3.4.10/bin/../build/classes:/usr/local/zookeeper-3.4.10/bin/../build/lib/*.jar:/usr/local/zookeeper-3.4.10/bin/../lib/slf4j-log4j12-1.6.1.jar:/usr/local/zookeeper-3.4.10/bin/../lib/slf4j-api-1.6.1.jar:/usr/local/zookeeper-3.4.10/bin/../lib/netty-3.10.5.Final.jar:/usr/local/zookeeper-3.4.10/bin/../lib/log4j-1.2.16.jar:/usr/local/zookeeper-3.4.10/bin/../lib/jline-0.9.94.jar:/usr/local/zookeeper-3.4.10/bin/../zookeeper-3.4.10.jar:/usr/local/zookeeper-3.4.10/bin/../src/java/lib/*.jar:/usr/local/zookeeper-3.4.10/bin/../conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg ; 运行程序的命令
