The su or su root operation is equivalent to the root user. the actual system environment is not switched.
To the root user environment, but only the current login user;
Su-,-l, and -- login are all completely switched to the root environment, which is equivalent to completely logging on with the root user. The service command directory is in/sbin/, so there are two ways to solve this problem: a. directly use su-root to switch to the root user, use service B, use su root to switch to the root user, and use/sbin/service at the same time, such as/sbin/service mysql restart.
