MySQL 5.7主要特性
1、更好的性能
对于多核CPU、固态硬盘、锁有着更好的优化，每秒100W QPS已不再是MySQL的追求，下个版本能否上200W QPS才是用户更关心的。
2、更好的InnoDB存储引擎
3、更为健壮的复制功能
复制带来了数据完全不丢失的方案，传统金融客户也可以选择使用。此外，GTID在线平滑升级也变得可能。
4、更好的优化器
优化器代码重构的意义将在这个版本及以后的版本中带来巨大的改进，Oracle官方正在解决MySQL之前最大的难题。
5、原生JSON类型的支持
6、更好的地理信息服务支持
InnoDB原生支持地理位置类型，支持GeoJSON，GeoHash特性
7、新增sys库
以后这会是DBA访问最频繁的库MySQL 5.7已经作为数据库可选项添加到《OneinStack》

添加mysql的环境变量
复制代码 代码如下:
[root@snails mysql-5.7.13]# echo -e ‘\n\nexport PATH=/usr/local/mysql/bin:$PATH\n’ >> /etc/profile && source /etc/profile
初始化数据库
复制代码 代码如下:
[root@snails mysql-5.7.13]# mysqld –initialize-insecure –user=mysql –basedir=/usr/local/mysql –datadir=/data/mysql
注：
- MySQL之前版本mysql_install_db是在mysql_basedir/script下
- MySQL 5.7直接放在了mysql_install_db/bin目录下。
- “–initialize”已废弃,生成一个随机密码(~/.mysql_secret)
- “–initialize-insecure”不会生成密码
- “–datadir”目录下不能有数据文件
启动数据库

设置数据库root用户密码
MySQL和Oracle数据库一样，数据库也默认自带了一个 root 用户（这个和当前Linux主机上的root用户是完全不搭边的），我们在设置好MySQL数据库的安全配置后初始化root用户的密码。配制过程中，一路输入 y 就行了。这里只说明下MySQL5.7.13版本中，用户密码策略分成低级 LOW 、中等 MEDIUM 和超强 STRONG 三种，推荐使用中等 MEDIUM 级别！

常用操作
将MySQL数据库的动态链接库共享至系统链接库
一般MySQL数据库还会被类似于PHP等服务调用，所以我们需要将MySQL编译后的lib库文件添加至当前Linux主机链接库 /etc/ld.so.conf.d/下，这样MySQL服务就可以被其它服务调用了。
