# 將mysql/bin加入環(huán)境變量，也就是/etc/profile文件中

# 加入默認(rèn)配置文件

bin/my_print_defaults --defaults-file=/usr/local/mysql/my.cnf

# 初始化數(shù)據(jù)文件

scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/mysql3306

scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/mysql3307

# 然后出來一大段英文大概教你怎么做

# 啟動(dòng)后先改密碼

# 否則執(zhí)行時(shí)指定配置文件

mysqld_multi --defaults-extra-file=/usr/local/mysql/my.cnf report

# or

mysqld_multi --defaults-file=/usr/local/mysql/my.cnf report

# or

mysqld_multi report

# 查看

mysqld_multi report

# 啟動(dòng)

mysqld_multi start 3306

# 停止

mysqld_multi stop 3306 --password=root

#or 最好用這個(gè)

mysqladmin -S /tmp/mysql_3306.sock -uroot -p shutdown

# 改密碼

mysqladmin -S /tmp/mysql_3307.sock -u root password 'root'

# 創(chuàng)建授權(quán)新用戶，開始使用
