CentOS6.5でmysql-5.7.18-linux-glibc 2をインストールします.5-x86_64

mysqlをインストールする前に、次のコマンドを実行します.

rpm -qa | grep mysql #  mysql    
yum -y remove mysql-libs-5.1.71-1.el6.x86_64 #  mysql-libs-5.1.71-1.el6.x86_64

まずmysql-5.7.18-linux-glibc 2をダウンロードします.5-x86_64.tar.gz、CentOS 6に伝える.5システム下の/usr/localディレクトリで、次のコマンドを実行します.

yum search libaio  # search for info
yum install libaio # install library
groupadd mysql
useradd mysql -g mysql
cd /usr/local
tar -zxvf /usr/local/mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.18-linux-glibc2.5-x86_64/ mysql
cd mysql/
mkdir data
cd ../
chown -R mysql:mysql mysql/
chmod -R 755 mysql/
cd mysql
./bin/mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize 

パスワードを検索します.一般的にコマンドの最後に、

mysql -uroot -po*s#gqh)F4Ck
alter user 'root'@'localhost' identified by '123456'; #  root    123456
use mysql;
update user set user.Host='%' where user.User='root';
flush privileges;

[root@localhost ~]# chkconfig mysql on #  mysql      

最後に、プロファイルを追加できます.
