這篇文章主要講解了centos7下如何安裝MySQL6初始化安裝密碼，內(nèi)容清晰明了，對(duì)此有興趣的小伙伴可以學(xué)習(xí)一下，相信大家閱讀完之后會(huì)有幫助。
創(chuàng)新互聯(lián)公司專注骨干網(wǎng)絡(luò)服務(wù)器租用十余年，服務(wù)更有保障！服務(wù)器租用，成都天府聯(lián)通服務(wù)器托管 成都服務(wù)器租用，成都服務(wù)器托管，骨干網(wǎng)絡(luò)帶寬，享受低延遲，高速訪問。靈活、實(shí)現(xiàn)低成本的共享或公網(wǎng)數(shù)據(jù)中心高速帶寬的專屬高性能服務(wù)器。
1.先停止數(shù)據(jù)庫服務(wù)器
service mysqld stop
2.vim /etc/my.cnf
3.配置文件添加skip-grant-tables
[root@VM_0_8_centos ~]# vim /etc/my.cnf # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [mysqld] # # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock skip-grant-tables 此處?。。。。。? # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0
4.重啟數(shù)據(jù)庫
systemctl restart mysql
5.登錄數(shù)據(jù)庫
mysql -uroot -p
如果詢問密碼，直接空密碼登錄
6.set password for root@localhost = password('123456');括號(hào)里面的密碼你自己修改。
7.mysql -uroot -p123456 登錄成功
PS：下面看下Mysql初始化root密碼和允許遠(yuǎn)程訪問
mysql默認(rèn)root用戶沒有密碼，輸入mysql –u root 進(jìn)入mysql
1、初始化root密碼
進(jìn)入mysql數(shù)據(jù)庫
mysql>update user set password=PASSWORD(‘123456') where User='root';
2、允許mysql遠(yuǎn)程訪問,可以使用以下三種方式:
a、改表。
mysql -u root –p mysql>use mysql; mysql>update user set host = '%' where user = 'root'; mysql>select host, user from user;
b、授權(quán)。
例如，你想root使用123456從任何主機(jī)連接到mysql服務(wù)器。
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
如果你想允許用戶jack從ip為10.10.50.127的主機(jī)連接到mysql服務(wù)器，并使用654321作為密碼
mysql>GRANT ALL PRIVILEGES ON *.* TO 'jack'@'10.10.50.127' IDENTIFIED BY '654321' WITH GRANT OPTION; mysql>FLUSH RIVILEGES
c:在安裝mysql的機(jī)器上運(yùn)行：
//進(jìn)入MySQL服務(wù)器 d:\mysql\bin\>mysql -h localhost -u root //賦予任何主機(jī)訪問數(shù)據(jù)的權(quán)限 mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION //使修改生效 mysql>FLUSH PRIVILEGES //退出MySQL服務(wù)器 mysql>EXIT
看完上述內(nèi)容，是不是對(duì)centos7下如何安裝mysql6初始化安裝密碼有進(jìn)一步的了解，如果還想學(xué)習(xí)更多內(nèi)容，歡迎關(guān)注創(chuàng)新互聯(lián)行業(yè)資訊頻道。
