腾讯轻量云主机，Docker容器部署Chemex IT资产管理系统
系统简介
☕咖啡壶（Chemex）是一个免费、开源、高效且漂亮的运维资产管理平台。软硬件资产管理、归属/使用者追溯、盘点以及可靠的服务器状态管理面板。基于优雅的Laravel框架和DcatAdmin开发
前期准备工作，云主机安装操作系统
环境：CentOS Linux release 7.6.1810 (Core)，Mysql-5.7.38
一、安装操作系统
1.1重置系统密码
安装系统后先重置下密码
1.2使用终端工具连接系统
使用XSHELL或其它终端连接工具，连接腾讯云主机，查看系统信息
二、准备Mysql安装包
一、下载Mysql安装包至目录mysql_download
2.1、下载Mysql安装包
1、新建目录：
mkdir mysql_download
2、切换到mysql_download目录：
cd mysql_download
3、下载Mysql安装包
清华大学开源软件镜像站源下载
wget https://mirrors.tuna.tsinghua.edu.cn/mysql/downloads/MySQL-5.7/mysql-5.7.38-1.el7.x86_64.rpm-bundle.tar --no-check-certificate
#--no-check-certificate 不认证网站证书，不加这个下载不下来
官方链接下载
wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.38-1.el7.x86_64.rpm-bundle.tar
2个下载地址2选一，都可以，清华大学的下载速度快一点
2.2、解压安装包
新建一个mysql文件夹，将安装文件解压到mysql目录下
mkdir mysql
解压到mysql目录
tar -xvf mysql-5.7.38-1.el7.x86_64.rpm-bundle.tar -C ./mysql
2.3、查看解压后的文件
进入mysql目录,查看解压后的文件对不对
切换到mysql目录
cd mysql
三、安装设置Mysql
3.1安装mysql
在mysql目录下执行下列命令进行安装
sudo yum install mysql-community-{server,client,common,libs}-*# 执行过程
[root@VM-12-12-centos mysql]# sudo yum install mysql-community-{server,client,common,libs}-*

Complete!
[root@VM-12-12-centos mysql]# 启动MySQL:
service mysqld start
重启MySQL：
service mysqld restart
停止MySQL：
service mysqld stop
查看MySQL状态：
service mysqld status
3.2 安装完毕后之后的设置
启动MySQL:
service mysqld start
查看MySQL状态：
service mysqld status
查看root的临时密码并登陆
sudo grep 'temporary password' /var/log/mysqld.log #查看密码
mysql -uroot -p #登录数据库
以下操作可以不做，使用默认规则也可以
登录数据库后
更改mysql密码策略级别为低，这样就可以设置简单密码了
set global validate_password_policy=LOW;
设置密码有效长度 4 位及以上，默认长度为最短8位数
set global validate_password_length=4;
修改root用户密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'chemex';
创建数据库，库名:chemex，一定要是chemex这个库名，不能用其他的
create database chemex;
退出mysql，操作完数据库后记得退出
exit
可选步骤
新建用户
CREATE USER 'chemex'@'%' IDENTIFIED BY 'chemex'; #创建用户chemex,设置密码为chemex,用户名跟密码请自定义，不想折腾的直接用root用户连接也行
用户授权
GRANT ALL PRIVILEGES ON *.* TO 'chemex'@'%' IDENTIFIED BY 'chemex' WITH GRANT OPTION;
命令解释：
GRANT：赋权命令
ALL PRIVILEGES：当前用户的所有权限
ON：介词
*.*：当前用户对所有数据库和表的相应操作权限
TO：介词
'chemex'@'%'：权限赋给chemex用户，所有ip都能连接
IDENTIFIED BY 'chemex'：连接时输入密码，密码为chemex
WITH GRANT OPTION：允许级联赋权四、部署Chemex
4.1 拉取docker镜像
Docker 部署方式不会建立数据库容器，也意味着你必须有一个已有的数据库，在启动 chemex 时候通过参数注入的方式连接数据库。
1、拉取chemex镜像
docker pull celaraze/chemex:latest
2、查看镜像
docker images 
4.2 启动容器
启动Docker容器
docker run -itd --restart=always -p 80:80 \
-e DB_HOST=数据库地址 \
-e DB_PORT=数据库端口 \
-e DB_DATABASE=数据库名称 \
-e DB_USERNAME=数据库账户 \
-e DB_PASSWORD=数据库密码 \
-e INSTALL=true \
celaraze/chemex
直接复制第2条的命令去启动容器即可
1、如果数据库连接地址设置为本地地址，则容器网络模式要设置为host模式：--net=host，命令如下：
docker run -itd --restart=always --net=host \
-e DB_HOST=127.0.0.1 \
-e DB_PORT=3306 \
-e DB_DATABASE=chemex \
-e DB_USERNAME=chemex \
-e DB_PASSWORD=chemex \
-e INSTALL=true \
celaraze/chemex
2、如果数据库连接地址设置为腾讯云主机公网IP地址，则不需要改变容器网络模式，命令如下：
记得填入ip地址
docker run -itd --restart=always -p 80:80 \
-e DB_HOST=云主机公网IP \
-e DB_PORT=3306 \
-e DB_DATABASE=chemex \
-e DB_USERNAME=chemex \
-e DB_PASSWORD=chemex \
-e INSTALL=true \
celaraze/chemex五、登录系统
在任意一台可以访问外网的电脑上，通过 http://腾讯云公网ip,即可 访问 chemex。,例如http://1.10.10.1
用户名与密码默认为admin
