./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql

如果執(zhí)行報錯

[root@dc1atmpapp12 mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql FATAL ERROR: please install the following Perl modules before executing ./scripts/mysql_install_db: Data::Dumper

解決方法是安裝autoconf庫

執(zhí)行命令：yum -y install autoconf

正確執(zhí)行上面命令以后

cp support-files/mysql.server /etc/init.d/mysqld

chmod 755 /etc/init.d/mysqld

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

2.4.修改啟動腳本

vi /etc/init.d/mysqld

2.4.1修改項：

basedir=/usr/local/mysql/

datadir=/usr/local/mysql/data/mysql

2.5.啟動服務(wù)

service mysqld start

2.6加入環(huán)境變量，編輯 /etc/profile，這樣可以在任何地方用mysql命令了

export PATH=$PATH:/usr/local/mysql//bin

source /etc/profile

2.7.測試連接

./mysql/bin/mysql -uroot

2.8.啟動mysql

service mysqld start

service mysqld status

2.9.創(chuàng)建用戶修改root密碼并授權(quán)

Mysql -uroot -p

set password=password('root');

FLUSH PRIVILEGES;

grant all privileges on *.* to root@"%" identified by 'root' with grant option;

FLUSH PRIVILEGES;
