centos二進制安裝MySQL-5.7數據庫

wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

mv mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz /usr/local/

cd /usr/local/

tar -zxvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

mv mysql-5.7.17-linux-glibc2.5-x86_64 mysql

cd mysql

cd support-files/

cp my-default.cnf /etc/my.cnf

vi /etc/my.cnf

輸入
[mysql]
default-character-set=utf8

[mysqld]
default-storage-engine=INNODB
character_set_server=utf8

拷貝mysql啓動文件
cp mysql.server /etc/init.d/mysql

vi /etc/init.d/mysql

在對應位置添加
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data

創建和mysql相關的用戶和用戶組

groupadd mysql
useradd -r -g mysql mysql
passwd mysql
chown -R mysql:mysql /usr/local/mysql/

usermod -d /home/mysql mysql

初始化數據庫
./mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

根據初始日誌記錄，得到root@localhost的初始密碼oEo&PI>hL46n

啓動數據庫

./mysqld_safe --user=mysql &


登錄後修改root密碼

./mysql -uroot -p
然後設置密碼爲chenli
set password=password('chenli');

grant all privileges on *.* to root@'%' identified by 'chenli';
grant all privileges on *.* to root@'192.168.1.98' identified by 'chenli';

flush privileges;

設置開機啓動
chkconfig --add mysql
chkconfig mysql on


GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'chenli' WITH GRANT OPTION;

GRANT ALL ON *.* TO 'root'@'%';
GRANT ALL ON *.* TO 'root'@'localhost';
GRANT ALL ON *.* TO 'root'@'127.0.0.1';

CREATE USER 'sa'@'%' IDENTIFIED BY 'chenli';
CREATE USER 'sa'@'localhost' IDENTIFIED BY 'chenli';
CREATE USER 'sa'@'127.0.0.1' IDENTIFIED BY 'chenli';

GRANT ALL ON *.* TO 'sa'@'%';

GRANT ALL ON *.* TO 'sa'@'localhost';
GRANT ALL ON *.* TO 'sa'@'127.0.0.1';
