MySQL 5.7 GA版本的发布，也就是说从现在开始5.7已经可以在生产环境中使用，有任何问题官方都将立刻修复。
MySQL 5.7主要特性：
- 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才是吾等用户更关心的
- 更好的InnoDB存储引擎
- 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MySQL数据库。此外，GTID在线平滑升级也变得可能
- 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
- 原生JSON类型的支持
- 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
- 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》
1 ) . Mysql环境安装配置：
安装依赖包: yum -y install gcc gcc-c++ ncurses ncurses-devel cmake 下载相应源码包： wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.13.tar.gz wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.13.tar.gz wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz 添加mysql用户: useradd -M -s /sbin/nologin mysql 预编译： tar zxvf boost_1_59_0.tar.gz cd boost_1_59_0 && ./bootstrap.sh && ./b2 && ./b2 install(解压就可以选择安装) tar zxvf mysql-5.7.13.tar.gz cd mysql-5.7.13 cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DDOWNLOAD_BOOST=1 -DWITH_BOOST=../boost_1_59_0 -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DENABLE_DTRACE=0 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_SYSTEMD=1 -DWITH_EMBEDDED_SERVER=1 (标红：加上-DWITH_SYSTEMD=1可以使用systemd控制mysql服务，默认是不开启systemd的) 编译安装： make -j `grep processor /proc/cpuinfo | wc -l` make install
1.1）. 数据库初始化：
cd /usr/local/mysql && chown -R mysql:mysql . bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data bin/mysql_ssl_rsa_setup chown -R root . && chown -R mysql data (标红："--initialize"会生成一个随机密码(~/.mysql_secret)，而"--initialize-insecure"不会生成密码，--datadir目标目录下不能有数据文件)
1.2) . 创建配置文件，启动数据库
mv /etc/my.cnf my.cnf.bak ---将默认生成my.cnf改名或删除否则启动服务会报错
cd /usr/local/mysql/support-files ---进入MySQL安装目录支持文件目录
cp my-default.cnf /etc/my.cnf ---复制模板为新的配置文件，根据需要修改文件中配置选项如不修改配置MySQL则按默认配置参数运行。
## mysql默认将mysqld.service文件安装到了mysql安装目录下的usr/lib/systemd/system/，将mysqld.service复制到/usr/lib/systemd/system/目录下
cd /usr/local/mysql/ && cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
## 在mysqld.service，把默认的pid文件指定到了/var/run/mysqld/目录，而并没有事先建立该目录，因此要手动建立该目录并把权限赋给mysql用户。
cd /var/run && sudo mkdir mysqld && sudo chown -R mysql mysqld && sudo chgrp -R mysql mysqld
## 启动mysql:
sysstemctl start mysqld
1.3）. 创建用户，并开放网络登录
/usr/loca/mysql/bin/mysql -uroot
use mysql;
UPDATE user SET authentication_string = PASSWORD('test2015') WHERE user = 'root';
GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'rootpasswd';
FLUSH PRIVILEGES;
## 创建用户：
create user bom;
update user set authentication_string=password("123456") where user="bom";
grant all on bom.* to 'bom'@'localhost';
create user backup;
update user set authentication_string=password("123456") where user="backup";
grant all on *.* to 'backup'@'localhost';
