SUSE 12 服務開機自啟動

SUSE 12 服務開機自啟動（ tomcat 開機自啟）

# 這裡/etc/init.d/after.local  就是我要做開機自啟的服務
# 這裡加入了要開機自啟的tomcat服務
suse12:~ # cat  /etc/init.d/after.local |egrep -v '^$|^#'

su - app -lc /app/tomcat-model/bin/startup.sh
su - app -lc /app/tomcat-ui/bin/startup.sh

# SUSE 12 支援systemctl 和 service 服務管理
# SUSE 11 隻支援 service ，且各種服務一重新開機就會挂掉，沒有開機自啟的服務管理
