Question

/etc/init.d/mysql start
通过shell命令执行时工作当放入bash脚本，然后执行bash脚本时工作但是，当我尝试从cronjob执行此脚本时我收到这个错误 /etc/init.d/mysql:73:start：not found
任何解释以及我如何解决这个问题我在Ubuntu 10.0上 oilChange.sh
#!/bin/bash service apache2 stop sleep 1s /etc/init.d/mysql stop sleep 1s /sbin/swapoff -a sleep 1s /sbin/swapon -a sleep 1s /etc/init.d/mysql start sleep 1s if [ pgrep mysql -c -le "0" ]; then /etc/init.d/mysql start; fi sleep 1s service apache2 start sleep 1s if [ pgrep apache -c -le "0" ]; then service apache2 start; fi sleep 1s cd /root/crt php twatch3.php

这是记录在/ var / mail / root

Rather than invoking init scripts through /etc/init.d, use the service(8)

Upstart job, you may also use the stop(8) utility, e.g. stop mysql
