systemctl enable rabbitmq-server.service
rabbitmqctl status

使用

rabbitmq-plugins enable rabbitmq_management ##启用管理模块
chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/
rabbitmqctl add_user mqadmin mqadminpassword
rabbitmqctl set_user_tags mqadmin administrator
rabbitmqctl set_permissions -p / mqadmin ".*" ".*" ".*"
http://[your-vultr-server-IP]:15672/  ## 使用管理端口访问
systemctl restart rabbitmq-server.service

Erlang安装

使用的系统是CENTOS7.X

安装命令如下：

cd /opt
yum install epel-release -y
wget https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
yum install erlang -y
[ -f /opt/erlang-solutions-1.0-1.noarch.rpm ] && rm /opt/erlang-solutions-1.0-1.noarch.rpm -rf
erl  ##输入这个命令，如果有版本等信息就表示安装成功

删除备份脚本

这个脚本的主要功能就是读取配置文件，然后根据需求保留备份的个数(备份的文件是以时间格式命名的)，删除最老的备份，以下是脚本内容：

#!/bin/bash
KEEP_NUM=2
for i in `cat /opt/sh/delete_backup.conf`
do
    CURRENT_NUM=`ls -l ${i} | grep -v total | wc -l`
    for((j=${CURRENT_NUM};j>${KEEP_NUM};j--))
    do
        FILE_NAME=`ls ${i} | sort -n | head -n 1`
        echo "删除的目录是： ${i}/${FILE_NAME}"
        cd ${i} && [ -d ${FILE_NAME} ] && rm ${FILE_NAME} -rf && sleep 1
    done
done

delete_backup.conf的内容是删除的目录

/opt/sh/testdir/a
/opt/sh/testdir/b

centos7初始化脚本

NAS安装迅雷进行离线下载

nas使用迅雷总的给我的使用感觉不好，如果种子不好的话，速度提不上来。个人感觉实际意义不是很大

在套件中心安装 docker 组件
打开刚刚安装好的 docker 组件，在注册表中搜索”yinheli/docker-thunder-xware”，并安装
创建一个文件夹”/docker/download/xunlei”。
在“映像”列表里选择刚刚下载好的镜像点击“启动”，并把第三步创建的文件夹挂载到”/TDdownload”下面
在端口设置这儿添加一个端口映射，我容器的端口和映射的端口都是9000
启动容器之后，点击刚刚启动那个容器的”详情”,然后再选择”日志”,在日志中找到”THE ACTIVE CODE IS”后面的激活码
登录 “http://yuancheng.xunlei.com ” ，并登录你自己的账号和密码，输入你的激活码并点击”绑定”
然后就可以愉快的使用了,使用的时候是在“http://yuancheng.xunlei.com”这个网址中添加种子等信息
