6.1. 直接用命令管理

启动hetao

$ hetao ~/etc/hetao.conf

查询hetao进程

$ ps -ef | grep hetao | grep -v grep
calvin   14876     1  0 00:10 ?  00:00:00 hetao /home/calvin/etc/hetao.conf
calvin   14877 14876  0 00:10 ?  00:00:00 hetao /home/calvin/etc/hetao.conf

优雅的重启hetao，或者重载配置文件

$ ps -ef | grep hetao | grep -v grep
calvin   14876     1  0 00:10 ?   00:00:00 hetao /home/calvin/etc/hetao.conf
calvin   14877 14876  0 00:10 ?   00:00:00 hetao /home/calvin/etc/hetao.conf
$ kill -USR2 14876
$  ps -ef | grep hetao | grep -v grep
calvin   14876     1  0 00:10 ?   00:00:00 hetao /home/calvin/etc/hetao.conf
calvin   14877 14876  0 00:10 ?   00:00:00 hetao /home/calvin/etc/hetao.conf
calvin   14889     1  0 00:12 ?  00:00:00 hetao /home/calvin/etc/hetao.conf
calvin   14890 14889  0 00:12 ?   00:00:00 hetao /home/calvin/etc/hetao.conf
$ kill 14876
$ ps -ef | grep hetao | grep -v grep
calvin   14889     1  0 00:12 ?  00:00:00 hetao /home/calvin/etc/hetao.conf
calvin   14890 14889  0 00:12 ?   00:00:00 hetao /home/calvin/etc/hetao.conf

向hetao发送重新打开日志文件信号

$ kill -USR1 14889

停止hetao

$ kill 14889
