linux_fedora nexus_auto_start

 

fedora20发布，不对rc.local支持，其实只是删除了rc.local文件，如果想在开机时能够运行自己写的脚本，只要新建rc.local文件就可以了，下面让我们来测试下吧：

环境：fedora20 GNOME桌面

1./etc/rc.local其实是/etc/rc.d/rc.local的软连接，那么:

vi /etc/rc.d/rc.local

#!/bin/bash
#this is a script foe nexus start,if the nexus is startting,return.
echo "nexus verify.."
testing8081=`(netstat -an|grep 8081)`
if [ "NULL$testing8081" = "NULL" ] ; then
        echo "nuxus starting..."
        /home/Jorcen/Environments/nexus/nexus-2.7.0-04/bin/nexus start
       else
        echo -n "nexus had started,do you need restart it?(Y/N):"
        read verify
        if [ "$verify" = "Y" ] ; then
                /home/Jorcen/Environments/nexus/nexus-2.7.0-04/bin/nexus restart
        echo "nexus restared.."
        fi
fi

chmod +x /etc/rc.d/rc.local

ln -s /etc/rc.d/rc.local /etc/rc.local

2.查看rc-local.service

systemctl status rc-local.service

如果服务没有启动可以先启动下rc-local.service

3.启动rc-local.service

systemctl start rc-local.service

然后用第2点的命令查看服务状态，这里可能有的服务启动不起来，为什么：

解决：

编辑文件/lib/systemd/system /rc-local.service,将ConditionFilel***ecutable=/etc/rc.d/rc.local前面奖赏#号注释掉 及#ConditionFilel***ecutable=/etc/rc.d/rc.local

再次启动下rc-local.service并用systemctl status rc-local.service看看状态是不是已经启动起来了

4.重启机器

查看/root下是不是多了个文件test，说明我们的开机脚本已经运行了！
