centos6 vps部署rails

centos 6 vps初始化部署rails应用
1 ssh登录 vps
ssh -p port root@server_ip_address

2 添加用户

adduser username
passwd username

3将用户添加到wheel组，得到sudo权限

vi /etc/sudoers

将%wheel ALL=(ALL) ALL 前面注释 #去掉，保存退出

usermod -aG wheel username

注意: 如果centos添加了authroized_keys不能无密码登录可能是权限问题
http://www.cnblogs.com/snowbook/p/5671406.html
原因是，不能让所有者之外的用户对authorized_keys文件有写权限，否则，sshd将不允许使用该文件，因为它可能会被其他用户篡改
authroized_keys修改成644
ssh配置文件中开起如下开启
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
