1-阿里云 CentOS 7.3 X64

2-安装NET CORE

教程地址：https://www.microsoft.com/net/core#linuxcentos

3-安装 libaio-0.3.109-13.el7.x86_64.rpm  （安装mysql 时出现 libaio.so.1(64bit) ....的问题）

下载：wget http://mirror.centos.org/centos/7.4.1708/os/x86_64/Packages/libaio-0.3.109-13.el7.x86_64.rpm

安装：rpm -ivh libaio-0.3.109-13.el7.x86_64.rpm

4-开始安装mysql 

4.1 查看 centos 版本

cat /etc/redhat-release 

 4.2 卸载 mariadb （系统自带）

    查看安装包：rpm -qa | grep mariadb 

    强制卸载：rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64

 查看是否安装了MySQL ： 

 1 ：rpm -qa | grep -i mysql

 2 ： find / -name mysql

删除文件：rm -r 递归删除命令

删除配置文件： rm -rf /etc/my.cnf 

然后重新检测一遍是否还有 mysql 文件

4.3 下载安装包

 下载地址：wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar

 4.4 解压安装包 ：tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar

  使用一下命令进行安装 ：rpm -ivh 文件名称 （下面是安装顺序）

  rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm

   rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-compat-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-devel-5.7.19-1.el7.x86_64.rpm

4.5 初始化设置：mysqld --initialize --user=mysql

   查看初始化密码：grep ‘temporary password‘ /var/log/mysqld.log

4.6 重启服务：systemctl restart mysqld.service

4.7 修改密码：SET PASSWORD=PASSWORD(‘123456‘); --修改成123456

5 配置远程链接

 5.1 添加 账号：

  ---添加本地账号

mysql> CREATE USER ‘monty‘@‘localhost‘ IDENTIFIED BY ‘some_pass‘;
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘monty‘@‘localhost‘
    ->     WITH GRANT OPTION;
--添加远程访问账号

mysql> CREATE USER ‘monty‘@‘%‘ IDENTIFIED BY ‘some_pass‘;
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘monty‘@‘%‘
    ->     WITH GRANT OPTION;

----把本地账号修改成远程可访问账号

update user set host = ‘%‘ where user = ‘monty‘;

FLUSH PRIVILEGES;  --如果不加这句，修改是不会生效的。
