补充(/etc/rc.d/rc.local 不属于任何服务,为特殊文件,可将不能定义为服务又想开机运行的命令定义在此文件中)
添加自定义服务:
# vi/etc/init.d/testsrv
#!/bin/bash
#chkconfig: 223 92 60
#description: programs at periodic scheduled times. vixie cron adds a \
# number of features to the basic UNIX cron, including better \
# security and more powerful configuration options.#
echo "hello"
# chkconfig --addtestsrv
# service testsrv
hello
