标签:问题 password 权限 pass c中 mode 修改 opera roo
自从Mac版本升级之后,各种不适应,service 命令竟然没了,百度了一下说是要修改/etc/sudoers ,在使用 chmod -R 777 /etc/sudoers 之后问题就来了,我竟然无法切换root用户,现在记录一下,解决办法
1.在Mac中启动root 账户

2.切换到root用户,修改 /etc/sudoers的权限
1 #无法使用chmod修改权限 2 demo:Desktop piaoyu.qiu$ ls -la /etc/sudoers 3 -rwxrwxrwx 1 root wheel 1371 8 9 11:28 /etc/sudoers 4 demo:Desktop piaoyu.qiu$ chmod 440 /etc/sudoers 5 chmod: Unable to change file mode on /etc/sudoers: Operation not permitted 6 7 #切换到root用户 8 demo:Desktop piaoyu.qiu$ su 9 Password:你自己设置的密码 10 sh-3.2# ls -l /etc/sudoers 11 -rwxrwxrwx 1 root wheel 1371 8 9 11:28 /etc/sudoers 12 sh-3.2# chmod 0440 /etc/sudoers 13 sh-3.2# ls -l /etc/sudoers 14 -r--r----- 1 root wheel 1371 8 9 11:28 /etc/sudoers 15 sh-3.2# exit
mac sudo: /etc/sudoers is world writable
