一. Nginx 开机启动
1、在/etc/init.d/目录下创建脚本
vim /etc/init.d/nginx
2、编写脚本内容 (将以下复制进去相应改动安装路径)
12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273 | #!/bin/bash # nginx Startup script for the Nginx HTTP Server # it is v.0.0.2 version. # chkconfig: - 85 15 # description: Nginx is a high-performance web and proxy server. # It has a lot of features, but it's not for everyone. # processname: nginx # pidfile: /var/run/nginx.pid # config: /usr/local/nginx/conf/nginx.conf //这里改成之前的安装目录 nginxd= /usr/local/webserver/nginx/sbin/nginx // 这里改成之前的安装目录 nginx_config= /usr/local/webserver/nginx/conf/nginx .conf // 这里改成之前的安装目录 nginx_pid= /usr/local/webserver/nginx/logs/nginx .pid // 这里改成之前的安装目录 RETVAL=0 prog= "nginx" # Source function library. . /etc/rc .d /init .d /functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up.

3、更改脚本权限
1 | chmod 775 /etc/init .d /nginx |
4、设置开机启动
1 | #chkconfig nginxd on |
二. MySQL开机启动
1、将mysql安装目录下 support-files目录下的mysql.server文件拷贝到/etc/init.d/目录下并改名为mysqld,并更改权限
1 | chmod 775 /etc/init .d /mysqld |
2、设置开机启动
1 | #chkconfig mysqld on |
三. PHP-fpm开机启动
1、在/etc/init.d/目录下创建脚本
1 | vim /etc/init .d /php-fpm |
2、编写脚本内容 (将以下复制进去相应改动安装路径)
1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556 | #!/bin/sh # # php-fpm - this script starts and stops the php-fpm daemin # # chkconfig: - 85 15 # processname: php-fpm # config: /usr/local/php/etc/php-fpm.conf set -e PATH= /usr/local/sbin : /usr/local/bin : /sbin : /bin : /usr/sbin : /usr/bin DESC= "php-fpm daemon" NAME=php-fpm DAEMON= /usr/local/php/sbin/ $NAME // 这里改成之前的安装目录 CONFIGFILE= /usr/local/php/etc/php-fpm .conf // 这里改成之前的安装目录 PIDFILE= /usr/local/php/var/run/ $NAME.pid // 这里改成之前的安装目录 SCRIPTNAME= /etc/init .d/$NAME // 这里改成之前的安装目录 # If the daemon file is not found, terminate the script. test -x $DAEMON || exit 0 d_start(){ $DAEMON -y $CONFIGFILE || echo -n " already running" } d_stop(){ kill -QUIT ` cat $PIDFILE` || echo -n " no running" } d_reload(){ kill -HUP ` cat $PIDFILE` || echo -n " could not reload" } case "$1" in start) echo -n "Starting $DESC: $NAME" d_start echo "." ;; stop) echo -n "Stopping $DESC: $NAME" d_stop echo "." ;; reload) echo -n "Reloading $DESC configuration..." d_reload echo "Reloaded." ;; restart) echo -n "Restarting $DESC: $NAME" d_stop # Sleep for two seconds before starting again, this should give the nginx daemon some time to perform a graceful stop sleep 2 d_start echo "." ;; *) echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload)" >&2 exit 3 ;; esac exit 0 |
最后:x 保存退出
3、更改脚本权限
1 | chmod 775 /etc/init .d /php-fpm |
4、设置开机启动
1 | #chkconfig php-fpm on |
可用命令 chkconfig 查看开机启动服务列表
CentOS设置服务开机启动的两种方法
1、利用 chkconfig 来配置启动级别
在CentOS或者RedHat其他系统下,如果是后面安装的服务,如httpd、mysqld、postfix等,安装后系统默认不会自动启动的。就算手动执行 /etc/init.d/mysqld start 启动了服务,只要服务器重启后,系统仍然不会自动启动服务。 在这个时候,我们就需要在安装后做个设置,让系统自动启动这些服务,避免不必要的损失和麻烦。 其实命令很简单的,使用chkconfig即可。

比如要将mysqld设置为开机自动启动:
1 | chkconfigmysqld on |
要取消掉某个服务自动启动,只需要将最后的参数 “on” 变更为 “off” 即可。
比如要取消 postfix 的自动启动:
1 | chkconfigpostfix off |
值得注意的是,如果这个服务尚未被添加到 chkconfig 列表中,则现需要使用 –-add 参数将其添加进去:
1 | chkconfig–-add postfix |
如果要查询当前所有自动启动的服务,可以输入:
1 | chkconfig-–list |
如果只想看指定的服务,只需要在 “–-list” 之后加上服务名就好了,比如查看httpd服务是否为自动启动:
1 | chkconfig–-listhttpd |
1 | httpd0:off1:off2:off3:off4:off5:off6:off |
此时0~6均为off,则说明httpd服务不会在系统启动的时候自动启动。我们输入:
1 | chkconfighttpd on |
则此时为:
1 | httpd0:off1:off2:on3:on4:on5:on6:off |
这个时候2~5都是on,就表明会自动启动了。
2、修改 /etc/rc.d/rc.local 这个文件:
例如将 apache、mysql、samba、svn 等这些服务的开机自启动问题一起搞定:
