前言
前面安装过mysql5.6，时隔三个月，开发那边反馈需要在MySQL中处理JSON类型的数据，查看文档，JSON是在5.7支持的新特性。于是着手安装Mysql57
Mysql5.6.28的安装：//www.jb51.net/article/103743.htm
安装
若使用apt-get install mysql-server进行安装，默认安装的不是最新的版本，于是考虑去官网找一个最新的社区版本。
1.获取最新的Mysql版本
在 https://dev.mysql.com/downloads/mysql/ 下选择操作系统版本（本例为Ubuntu），下载的时候注意要和操作系统版本相匹配（OS版本对应安装包版本）。
# cat /etc/issue Ubuntu 12.04.5 LTS \n \l # wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-server_5.7.17-1ubuntu12.04_amd64.deb-bundle.tar
2.具体安装（因为依赖报的关系，需要注意安装次序）
# tar -xvf mysql-server_5.7.17-1ubuntu12.04_amd64.deb-bundle.tar # ll total 712948 drwxr-xr-x 2 root root 4096 Jan 20 10:07 ./ drwxr-xr-x 5 root root 4096 Jan 19 19:23 ../ -rw-r--r-- 1 7155 31415 1356802 Nov 29 03:30 libmysqlclient20_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 1904116 Nov 29 03:30 libmysqlclient-dev_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 30791660 Nov 29 03:29 libmysqld-dev_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 12998 Nov 29 03:30 mysql-client_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 82798 Nov 29 03:30 mysql-common_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 6831 Nov 29 03:30 mysql-community_5.7.17-1ubuntu12.04_amd64.changes -rw-r--r-- 1 7155 31415 21519804 Nov 29 03:30 mysql-community-client_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 55477882 Nov 29 03:29 mysql-community-server_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 208582030 Nov 29 03:30 mysql-community-source_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 45244026 Nov 29 03:30 mysql-community-test_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 7155 31415 12990 Nov 29 03:30 mysql-server_5.7.17-1ubuntu12.04_amd64.deb -rw-r--r-- 1 root root 365015040 Nov 30 02:11 mysql-server_5.7.17-1ubuntu12.04_amd64.deb-bundle.tar -rw-r--r-- 1 7155 31415 13014 Nov 29 03:30 mysql-testsuite_5.7.17-1ubuntu12.04_amd64.deb ###安装依赖包 sudo apt-get upgrade sudo apt-get install libaio1 ###安装deb包 sudo dpkg -i mysql-common_5.7.17-1ubuntu12.04_amd64.deb sudo dpkg -i libmysqlclient20_5.7.17-1ubuntu12.04_amd64.deb sudo dpkg -i libmysqlclient-dev_5.7.17-1ubuntu12.04_amd64.deb sudo dpkg -i libmysqld-dev_5.7.17-1ubuntu12.04_amd64.deb sudo dpkg -i mysql-community-client_5.7.17-1ubuntu12.04_amd64.deb sudo dpkg -i mysql-client_5.7.17-1ubuntu12.04_amd64.deb sudo dpkg -i mysql-community-source_5.7.17-1ubuntu12.04_amd64.deb ###libmecab2 安装 sudo apt-get -f install sudo dpkg -i mysql-community-server_5.7.17-1ubuntu12.04_amd64.deb ###这边会提示设置root密码
基本配置（和以前的5.6版本有差异）
1.新增用户，赋权
create user testuser identified by '*******'; create database testdb; GRANT ALL ON testdb.* TO 'testuser'@'%' ; flush privileges; --root用户远程访问权限开放 mysql> use mysql; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> select host,user from user; +-----------+-----------+ | host | user | +-----------+-----------+ | % | testuser | | localhost | mysql.sys | | localhost | root | +-----------+-----------+ 3 rows in set (0.00 sec) mysql> update user set host = '%' where user ='root'; Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> select host,user from user; +-----------+-----------+ | host | user | +-----------+-----------+ | % | testuser | | % | root | | localhost | mysql.sys | +-----------+-----------+ 3 rows in set (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
2.配置文件修改
配置文件路径（相比以前版本有变更，56路径：/etc/MySQL/my.conf）
57路径： /etc/mysql/mysql.conf.d/mysqld.cnf
–绑定IP修改
找到bind-address = 127.0.0.1这一行
改为bind-address = 0.0.0.0，问题解决。
–大小写区分修改
[mysqld]后添加添加lower_case_table_names=1，重启MYSQL服务，这时已设置成功：不区分表名的大小写；
lower_case_table_names参数详解：
lower_case_table_names = 0
其中 0：区分大小写，1：不区分大小写
其他
基本的服务启停命令没有改变
# 启动MySQL$ sudo service mysql start # 关闭MySQL$ sudo service mysql stop # 重启MySQL$ sudo service mysql restart # 其他命令：$ sudo /etc/init.d/mysql start $ sudo /etc/init.d/mysql stop $ sudo /etc/init.d/mysql restart
