二进制安装MySQL5.6 MySQL5.7

1:系统版本

[root@vhost1 ~]# cat /etc/redhat-release

Red Hat Enterprise Linux Server release 6.5 (Santiago)

2:添加用户和组

chattr -i /etc/shadow /etc/group /etc/gshadow /etc/passwd

/usr/sbin/groupadd -g 200 mysql

/usr/sbin/useradd mysql -u200 -g mysql -s /sbin/nologin

3:启动文件、my.cnf文件、创建MySQL软件目录

/opt/source #软件解压目录

basedir=/usr/local/mysql #软件安装目录

datadir=/mysqldata #数据目录

解压软件到安装目录下

#tar zxvf  mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz -C /usr/local/mysql

在软件目录/opt/source下解压

tar zxvf  mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz

mv  mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz mysql

建立软连接,便于日后版本升级

ln -r /opt/source/mysql /usr/local/mysql 

 

chattr +i /etc/shadow /etc/group /etc/gshadow /etc/passwd

chown -R mysql:mysql $basedir $basedir #改权限

创建启动MySQL启动文件

cp -rf $basedir/support-files/mysql.server /etc/init.d/mysql

/sbin/chkconfig --add mysql

/sbin/chkconfig --level 2345 mysql on

创建执行文件的链接文件 

ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql 

ln -s /usr/local/mysql/bin/mysqldump /usr/bin/mysqldump

ln -s /usr/local/mysql/bin/mysqladmin /usr/bin/mysqladmin

ln -s /usr/local/mysql/bin/mysqld /usr/bin/mysqld

ln -s /usr/local/mysql/bin/mysqlshow /usr/bin/mysqlshow

4:编辑my.cnf 

cp $basedir/support-files/my.cnf.nor /etc/my.cnf

vi /etc/my.cnf

[mysqld]中添加:

server_id = 1

port = 3306

basedir = /usr/local/mysql datadir = /mysqldata

5:初始化数据字典

>5.6 初始化mysql表、test表、infomation表等

mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/mysqldata

PS:该步骤有可能会报错误 安装需要的包即可:libstdc++.so.6和libaio.so.1和libncurses.so.5

>5.7

mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/mysqldata

#会生成随机密码。加--initialize初始化时候保持5.5,5.6一致,生成空密码

注意,记住初始化数据库生成登录MySQL数据库的root密码,一会登录数据库要用 

6;启动MySQL服务

service mysql start

grep password*.log

set password=password('mysql'); 

7:登陆MySQL

5.6 删除空用户

select user,host from mysql.user;

mysql> DROP USER ''@localhost;

mysql> UPDATE mysql.user set password = PASSWORD('gechong') WHERE user = 'root';

mysql> FLUSH PRIVILEGES;

5.7

mysql> set password='123456';  (因为刚才使用的密码是个默认的登录密码,所以我们要修改)

mysql>  flush privileges;
