[mysql] linux 下mysql 5.7.12 安装

1.下载mysql

wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.12-1.el6.x86_64.rpm-bundle.tar
2. 解压

tar -xf mysql-5.7.12-1.el6.x86_64.rpm-bundle.tar

解压完成后由这么几个文件：

mysql-community-client-5.7.12-1.el6.x86_64.rpm
mysql-community-common-5.7.12-1.el6.x86_64.rpm
mysql-community-devel-5.7.12-1.el6.x86_64.rpm
mysql-community-embedded-5.7.12-1.el6.x86_64.rpm
mysql-community-embedded-devel-5.7.12-1.el6.x86_64.rpm
mysql-community-libs-5.7.12-1.el6.x86_64.rpm
mysql-community-libs-compat-5.7.12-1.el6.x86_64.rpm
mysql-community-server-5.7.12-1.el6.x86_64.rpm
mysql-community-test-5.7.12-1.el6.x86_64.rpm

3.开始安装

根据需要安装：

mysql-community-client-5.7.12-1.el6.x86_64.rpm
mysql-community-common-5.7.12-1.el6.x86_64.rpm

mysql-community-libs-5.7.12-1.el6.x86_64.rpm

mysql-community-server-5.7.12-1.el6.x86_64.rpm

执行安装：

rpm -ivh mysql-community-common-5.7.12-1.el6.x86_64.rpm

4.启动mysql

service mysql start

或者使用如下命令：

/etc/init.d/mysql start

5. 此处没有设置密码，会报错

#1045 - Access denied for user 'root'@'localhost' (using password: NO)

解决方法是用安全方式登录，修改密码即可。



mysql安全方式启动:

mysqld_safe --user=mysql --skip-grant-tabes --skip-networking &

或者

/usr/local/mysql/bin/mysqld_safe --skip-grant-tables &

由于mysql5.7 中mysql.user 表中没有Password字段，用authentication_string 代替即可。

6. 至此mysql安装完成，可用客户端工具连接使用了.
