2.目錄規範

要避免應用遷移時路徑衝突

[[email protected] serivce]# ls
user
[[email protected] serivce]# cd user
[[email protected] user]# ls
edu-service-user.jar  lib  service-user.sh
[[email protected] user]# chmod 777 service-user.sh 
[[email protected] user]# ./service-user.sh start
=== start edu-service-user
[[email protected] user]# 

停止、重啟服務

[[email protected] user]# ./service-user.sh stop
=== stop edu-service-user
=== edu-service-user process not exists or stop success
[[email protected] user]# ./service-user.sh restart
cat: /home/yxq/edu/serivce/user/edu-service-user.pid: No such file or directory
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
=== stop edu-service-user
=== edu-service-user process not exists or stop success
=== start edu-service-user
=== restart edu-service-user
[[email protected] user]# 

service-user.sh指令碼

1. #!/bin/sh
2. ## java env

32.             kill -9 $P_ID

指令碼命名規範

/hom/yxq/edu/service/xxx/service-xxx.sh

例如:

/home/yxq/edu/serivce/user/service-user.sh

效果

./service-user.sh start

./service-user.sh stop

./service-user.sh restart

5.手動維護注意事項(結合自定義的Shell指令碼)

(1)指令碼規範--儘可能通用

(2)守護程序

(3)記憶體調優設定--按需調整

(4)日誌處理--只保留應用log4j輸出的日誌

(5).避免服務衝突--程序名、埠

(6)避免程序誤殺--全匹配
