简单安装Mysql（linux centos）

之前写了几篇mysql多实例或主备安装文章，但由于实验需要，反而要一个快速简单部署的mysql，so mark如下：

--------------------

rm /appl/mysql/data/dbdata

scripts/mysql_install_db --user=root --basedir=/appl/mysql --datadir=/appl/mysql/data/dbdata

bin/mysqld_safe --basedir=/appl/mysql --user=root &

mysql -uroot
show databases;
GRANT ALL PRIVILEGES ON *.* TO root@localhost IDENTIFIED BY "root";
GRANT ALL PRIVILEGES ON *.* TO root@centos1 IDENTIFIED BY "root";
FLUSH PRIVILEGES;
use mysql;
show tables;
select host,user,password from user;
exit

mysql -uroot -proot (或mysql -hcentos1 -uroot -proot）

use test;
create table bigdata (id int, name char(10));
insert into bigdata values(1,'a');
commit;
select * from bigdata;
exit

/appl/mysql/my.cnf
[mysqld]
server-id = 1
port = 3306
socket = /tmp/mysql.sock
datadir = /appl/mysql/data/dbdata
