1.创建用户和登录shell
useradd -s /bin/bash monitor

2.修改用户密码

passwd monitor

3.创建用户shell执行命令目录

mkdir /home/monitor/.bin

4.root修改用户的shell配置文件

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

5.修改bash配置文件，主要是指定PATH的读取

[swallet@iZj6c6g9pt4wd4xt1xi69zZ ~]$ cat .bash_profile 
# .bash_profile# Get the aliases and functions
if [ -f ~/.bashrc ]; then. ~/.bashrc
fi# User specific environment and startup programsPATH=$PATH:$HOME/.local/bin:$HOME/binexport PATH

#切换到只读账号使环境变量生效

su - monitor
source /home/monitor/.bash_profile

6.将允许执行的命令链接到$HOME/.bin目录

ln -s /usr/bin/wc /home/monitor/.bin/wc
ln -s /usr/bin/tail /home/monitor/.bin/tail
ln -s /bin/more /home/monitor/.bin/more
ln -s /bin/cat /home/monitor/.bin/cat
ln -s /bin/grep /home/monitor/.bin/grep
ln -s /bin/find /home/monitor/.bin/find
ln -s /bin/pwd /home/monitor/.bin/pwd
ln -s /bin/ls /home/monitor/.bin/ls
ln -s /bin/less /home/monitor/.bin/less
ln -s /bin/tar /home/monitor/.bin/tar

第二步：在相应服务的log日志文件夹授权

chmod说明(u:与文件属主拥有一样的权限[a:所有人]；+:增加权限;rwx:可读可写可执行）   -R:递归所有目录和文件

chmod a+rwx -R /data/logs
