setup 、rc.local 和chkconfig三种方式都可以设置
第一种)
输入#setup指令进入系统服务菜单，选择你想启动的服务比如httpd，然后重起机器或者 /etc/rc.d./init.d/httpd start
第二种)
把启动命令放到/etc/rc.d/rc.local文件里这样就可以每次启动的时候自动启动服务了,例如对于 apache,编译好apache后会在安装目录的bin下生成apachectl文件,这是个启动教本,我们只需要把这个命令加到rc.local里就可以了
echo /usr/local/apache/bin/apachectl >> /etc/rc.d/rc.local,
设置服务自动启动的方式是在rc.local里还可以加入类似以下的一些脚本：
#sshd
/usr/local/sbin/sshd
#proftpd
/usr/local/sbin/proftpd
#apache
/home/apache/bin/apachectl start
#mysql
/home/mysql/bin/safe_mysqld --port=3306 &
#start oracle8i listener first
su - oracle -c 'lsnrctl start'
#start oracle8i
su - oracle -c 'dbstart'
第三种)
通过chkconfig指令.
使用chkconfig命令来把某项服务加到系统的各项运行级别中,步骤如下,
1 创建启动脚本.
对于apache,mysql,ssh这样的软件都是自己带的,我们只要稍微修改一下使之支持chkconfig就可以了
2 修改脚本
我们需要在脚本的前面加上一下2行,才能支持chkconfig命令
# chkconfig: 2345 08 92
#
# description: Automates a packet filtering firewall with ipchains.
#
chkconfig:后面定义的使启动服务的运行级别(例子中使2345启动改服务),以及关闭和启动服务的顺序,(上例中关闭服务的顺序使8,启动的顺序使92)
descriptions:对改服务的描述(上例中是ipchains包过滤),你可以换成自己想要的
修改好之后执行
cp 你的脚本 /etc/rc.d/init.d/脚本名
chmod 700 /etc/rc.d/init.d/脚本名
chkconfig --add 脚本名
例如:
将其加入Linux启动过程，仅在level 3, level 5级别下运行
[root@Tester init.d]/sbin/chkconfig --add apache-httpd
[root@Tester init.d]/sbin/chkconfig --level 35 apache-httpd on
之后就可以了,以后每次重新启动服务器都会自动启动和关闭我们的服务了
下面是网路上一些创建的APACHE启动脚本案例,可以参考一下:
Linux下设置apache httpd服务为自动启动的实现：
系统环境： RED HAT ENTERPRISE AS 4
Apache Httpd 版本： 2.0.61
Apache 安装路径： /usr/local/apache-httpd-2.0.61
Step 1:
[buck@Tester local]ln -s /usr/local/apache-httpd-2.0.61 apache-httpd-default
Step 2:
切换到超级用户，进入/etc/init.d/，创建启动脚本
[root@Tester init.d]vi appache-httpd
#!/bin/bash
