Linux创建只读用户

一、创建用户

useradd -s /bin/bash dbmon

----Aix系统:
useradd -s /usr/bin/ksh -m  -G oinstall  dbmon;

二、设置密码

echo "@dbmon_123p" | passwd --stdin dbmon

----Aix系统:
passwd  dbmon;

三、创建用户执行命令目录

mkdir /home/dbmon/.bin

四、root修改用户的shell配置文件

chown root. /home/dbmon/.bash_profile
chmod 755 /home/dbmon/.bash_profile

----Aix系统:
chown root. /home/dbmon/.profile
chmod 755 /home/dbmon/.profile

五、修改bash配置文件，主要是指定PATH的读取

vi /home/dbmon/.bash_profile
#PATH=$PATH:$HOME/.local/bin:$HOME/bin
PATH=$HOME/.bin
export PATH

----Aix系统:
vi /home/dbmon/.profile
#PATH=$PATH:$HOME/.local/bin:$HOME/bin
PATH=$HOME/.bin
export PATH

六、将允许执行的命令链接到$HOME/.bin目录

ln -s /usr/bin/wc /home/dbmon/.bin/wc
ln -s /usr/bin/tail /home/dbmon/.bin/tail
ln -s /bin/more /home/dbmon/.bin/more
ln -s /bin/cat /home/dbmon/.bin/cat
ln -s /bin/grep /home/dbmon/.bin/grep
ln -s /bin/find /home/dbmon/.bin/find

ln -s /bin/df /home/dbmon/.bin/df
ln -s /usr/bin/du /home/dbmon/.bin/du
ln -s /usr/bin/uptime /home/dbmon/.bin/uptime
ln -s /usr/bin/last /home/dbmon/.bin/last
ln -s /usr/bin/top /home/dbmon/.bin/top
ln -s /usr/bin/free /home/dbmon/.bin/free
ln -s /usr/bin/vmstat /home/dbmon/.bin/vmstat
ln -s /bin/netstat /home/dbmon/.bin/netstat
ln -s /bin/ping /home/dbmon/.bin/ping
ln -s /usr/bin/xargs /home/dbmon/.bin/xargs

ln -s /usr/bin/wc /home/dbmon/.bin/wc
ln -s /usr/bin/tail /home/dbmon/.bin/tail
ln -s /usr/bin/more /home/dbmon/.bin/more
ln -s /usr/bin/cat /home/dbmon/.bin/cat
ln -s /usr/bin/grep /home/dbmon/.bin/grep
ln -s /usr/bin/find /home/dbmon/.bin/find
ln -s /usr/bin/pwd /home/dbmon/.bin/pwd
ln -s /usr/bin/ls /home/dbmon/.bin/ls
ln -s /usr/bin/tar /home/dbmon/.bin/tar
ln -s /usr/bin/awk /home/dbmon/.bin/awk
ln -s /usr/bin/cut /home/dbmon/.bin/cut
ln -s /usr/bin/df /home/dbmon/.bin/df
ln -s /usr/bin/du /home/dbmon/.bin/du
ln -s /usr/bin/uptime /home/dbmon/.bin/uptime
ln -s /usr/bin/last /home/dbmon/.bin/last
ln -s /usr/bin/top /home/dbmon/.bin/top
ln -s /usr/bin/free /home/dbmon/.bin/free
ln -s /usr/bin/vmstat /home/dbmon/.bin/vmstat
ln -s /usr/bin/netstat /home/dbmon/.bin/netstat
ln -s /usr/bin/ping /home/dbmon/.bin/ping
ln -s /usr/bin/xargs /home/dbmon/.bin/xargs

----Aix系统:
ln -s /usr/bin/wc /home/dbmon/.bin/wc
ln -s /usr/bin/tail /home/dbmon/.bin/tail
ln -s /usr/bin/more /home/dbmon/.bin/more
ln -s /usr/bin/cat /home/dbmon/.bin/cat
ln -s /usr/bin/grep /home/dbmon/.bin/grep
ln -s /usr/bin/find /home/dbmon/.bin/find
ln -s /usr/bin/pwd /home/dbmon/.bin/pwd
ln -s /usr/bin/ls /home/dbmon/.bin/ls
ln -s /bin/tar /home/dbmon/.bin/tar
ln -s /bin/awk /home/dbmon/.bin/awk

ln -s /usr/bin/netstat /home/dbmon/.bin/netstat
ln -s /etc/ping /home/dbmon/.bin/ping
ln -s /usr/bin/xargs /home/dbmon/.bin/xargs

七、切换dbmon，使用配置生效

su - dbmon
source /home/dbmon/.bash_profile
