不会写脚本,但是云平台翻车,手工配也太慢了所以还是糊了个


DBA:需要配置 oracle root grid 三个用户的相互互信,包括自身
也就是整合了一下命令。虽然也加进去了 Linux 的,但是接触不到 Linux Oracle 环境没试过效果

#!/bin/ksh
# AIX

# if [[ "$OSTYPE" == "linux-gnu"* ]]; then
#     # for Linux
#     su - root
#     ssh-keygen -t rsa -f "test_rsa" -N ""

#     runuser -l oracle -c 'ssh-keygen -t rsa -f "test_rsa" -N ""'
#     runuser -l grid -c 'ssh-keygen -t rsa -f "test_rsa" -N ""'

# else
#     # for aix, more
#     su - root -c 'ssh-keygen -t rsa -f "test_rsa" -N ""'
#     su - oracle -c 'ssh-keygen -t rsa -f "test_rsa" -N ""'
#     su - grid -c 'ssh-keygen -t rsa -f "test_rsa" -N ""'
