logstash服务启动脚本

最近在弄ELK，发现logstash没有sysv类型的服务启动脚本，于是按照网上一个老外提供的模板自己进行修改

#添加用户
useradd logstash -M -s /sbin/nologin
mkdir /var/log/logstash/
chown -R logstash:logstash /var/log/logstash/
chown -R logstash:logstash /usr/local/logstash-2.0.0/





vi /etc/init.d/logstash
#!/bin/bash

chmod +x /etc/init.d/logstash
#设置开机启动
chkconfig --add logstash
chkconfig logstash on
