由于管理严格，通常拿不到root权限，但是启停crs还得用root，需要申请，走流程，麻烦！
想了想，是不是有个sudo命令可以不用root密码了？
到底哪些命令需要呢？查了查发现这个地方有些提示：
可以对以下命令设置sudo：
/u01/app/12.1.0/grid/bin/crsctl
/u01/app/12.1.0/grid/bin/appvipcfg
/u01/app/12.1.0/grid/bin/srvctl
/u01/app/12.1.0/grid/bin/acfsroot
/u01/app/12.1.0/grid/bin/acfsload
/u01/app/oraInventory/orainstRoot.sh
/u01/app/12.1.0/grid/root.sh
/u01/app/oracle/product/12.1.0/dbhome_1/root.sh
/u01/app/12.1.0/grid/OPatch/opatchauto
好的，我准备编辑一下，通过visudo命令一运行，猜我看到了什么：
往下拉
## Allow root to run any commands anywhere
oracle ALL=(ALL) ALL
grid ALL=(ALL) ALL
root ALL=(ALL) ALL
顿时内牛满面，都给你了还不知道，还申请个屁。
干他
