1.下载源码包
在mysql官网选择合适的版本，得到下载的url
https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22.tar.gz 或者直接修改url
使用wget命令下载
cd /usr/local/srcwget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22.tar.gz下载完成之后解压安装包
tar -zxvf mysql-5.7.22.tar.gz下载boost
wget http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gztar -zxvf boost_1_59_0.tar.gz
mv boost_1_59_0 /usr/local/boost进入mysql安装包
cd /usr/local/src/mysql-5.7.222.安装
卸载CentOS7默认携带的mariadb包
rpm -qa | grep -i mysql
rpm -qa | grep -i mariadb
卸载时，发现有依赖一起卸载掉
rpm -e mariadb-libs-5.5.56-2.el7.x86_64rpm -e mariadb-libs-5.5.56-2.el7.x86_64 postfix-2:2.10.1-6.el7.x86_64
先安装一些依赖库

vi /etc/profile增加
/usr/local/mysql/bin:
刷新环境变量
source /etc/profile设置开机自启动
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld启动mysql
mysqld_safe --defaults-file=/etc/my.cnf &查看mysql进程
ps -ef | grep mysql
登陆MySQL
mysql -uroot
修改密码
SET PASSWORD = PASSWORD('123456');
退出mysql
quit;重新登录mysql
mysql -uroot -p输入上面设置的密码：123456
成功登录
配置远程访问
use mysql;
UPDATE user SET host = '%' WHERE user = 'root';
重启mysql
quit;
/etc/init.d/mysqld restart
使用 Navicat连接
使用 cmd 连接mysql（需安装Windows的mysql）
