配置CentOS

root帐号登录服务器

查看版本
cat /etc/issue
#CentOS release 5.2 (Final)
调整时区时间
sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
sudo /usr/sbin/ntpdate us.pool.ntp.org
很简单吧,解析一下,第一句是把当前时区调整为上海就是+8区,想改其他时区也可以去看看/usr/share/zoneinfo目录;然后第二句 是利用ntpdate同步标准时间.
没有ntpdate的可以yum一下: yum install -y ntpdate

新建用户
useradd app
passwd app
#Changing password for user app.
#New UNIX password:
#Retype new UNIX password:
#passwd: all authentication tokens updated successfully.

#add app to sudoer
vi /etc/sudoers

#add line
app     ALL=(ALL)NOPASSWD:ALL

#test
su app
sudo ls -all

配置自动登录
su app
cd /home/app/
mkdir .ssh
touch .ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

#回到本地机器
cd ~
#生成密钥对：
#ssh-keygen -t rsa
cat  ~/.ssh/id_rsa.pub | ssh app@116.255.153.187 "cat - >> ~/.ssh/authorized_keys"
#test
ssh app@211.152.56.151
