https://www.bt.cn/bbs/forum.php?mod=viewthread&tid=1186
yum install -y wget && wget -O install.sh http://download.bt.cn/install/install_6.0.sh && sh install.sh
安装成功后，把下面的宝塔控制面板地址记住：
外网面板地址: https://SERVER_IP:11080/d8f52957
内网面板地址: https://172.168.0.100:11080/d8f52957

If you cannot access the panel,
release the following panel port [11080] in the security group
若无法访问面板，请检查防火墙/安全组是否有放行面板[11080]端口
因已开启面板自签证书，访问面板会提示不匹配证书，请参考以下链接配置证书

5.配置宝塔LAMP

7.添加CRM站点，添加站点设置目录
8.创建数据库
得到数据库名称和密码
9.初始化Vtiger CRM
登录http://172.168.0.100/index.php，进行配置
主要配置数据库连接和管理员密码
可能会遇到如下错误，主要是因为版本兼容问题：
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; UserTimeZones has a deprecated constructor in /www/crm/modules/Users/UserTimeZonesArray.php on line 15
Deprecated: Function get_magic_quotes_gpc() is deprecated in /www/crm/includes/http/Request.php on line 25
MySQL Server should be configured with:
[mysqld]
sql_mode = ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
找到/etc/my.cnf，添加sql_mode.
10.登录Viger CRM进行后续的配置操作, 学习和了解这个开源CRM系统
