centos7通过rc.local文件添加自启动服务

centos7通过rc.local文件添加自启动服务：

---

系统环境:

• Centos 7

---

1、赋予脚本执行权限

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

---

2、自动服务

systemctl enable rc-local.service
systemctl start rc-local.service
systemctl status rc-local.service

---

3、添加启动脚本

[root@threegene-mongodb-4ee43df-prd ~]# more /etc/rc.local
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
/usr/local/services/mongodb/bin/mongod -f /home/middle/mongodb/conf/mongo.cnf
/usr/local/services/mongodb_arbiter/bin/mongod -f /home/middle/mongodb_arbiter/conf/mongo.cnf
