Linux下二进制包安装mysql-5.7.14

mysql5.7的安装和mysql5.6的安装变化蛮大的.我一开始按照官方文档的说明安装的,根本不行,不得不吐槽一下mysql的官方安装文档很差,和mongodb的没法比.

注意:在使用二进制包安装mysql的时候,确保你的系统上没有以前的使用yum或者rpm安装的旧的mysql,如果存在,使用rpm -e命令来删除.包括删除/etc/my.cnf

下面是安装步骤:

1.创建mysql用户和组

1. groupadd mysql
2. useradd -r -g mysql -s /bin/false mysql

2.解压缩安装包

1. tar zxvf mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
2. cd /usr/local
3. ln -sv mysql-5.7.14-linux-glibc2.5-x86_64 mysql

3.创建数据文件目录并且赋权

1. cd /usr/local/mysql
2. chown -R mysql.mysql *

这里我将mysql数据文件放在/data/mysql/data下

1. mkdir -p /data/mysql/data
2. chown -R mysql:mysql /data/mysql/data

4.创建mysql配置文件

这里我直接拷贝了以前使用的my.cnf,其中有些参数已经被遗弃.数据目录,日志目录根据现实环境修改:

1. vi /etc/my.conf
3. [mysqld]

5.初始化mysql

在5.6初始化使用scripts/mysql_install_db来实现,而5.7.6以后的版本则使用bin/mysqld --initialize来实现

根据上面的my.conf来初始化:

1. cd /usr/lcoal/mysql
2. bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data --pid-file=/data/mysql/data/mysql.pid
3. chown -R root .

6.将mysql设置为服务

1. cp support-files/mysql.server /etc/init.d/mysqld
2. chkconfig --add mysqld
3. chkconfig --level 35 mysqld on

7.启动连接mysql

这时你就可以启动mysql了

1. service mysqld start

5.7以后root密码写在/root/.mysql_secret下

1. cat /root/.mysql_secret
2. mysql -uroot -p
3. Enter password:

8.其他

我这里安装完成之后使用.mysql_secret的密码总是报错密码错误.解决办法是,

先在my.cnf中添加skip-grant-tables参数来跳过授权表

然后启动数据库.再执行下面的语句:

1. mysql> flush privileges;
2. Query OK, 0 rows affected (0.32 sec)
3. mysql> set password for root@'localhost'=password('root');
4. Query OK, 0 rows affected, 1 warning (0.00 sec)
5. mysql> flush privileges;
6. Query OK, 0 rows affected (0.00 sec)

mysql5.7的mysql.user中不再存放passwod列,因此不能直接update了.
