卸載系統(tǒng)自帶mariadb數(shù)據(jù)庫(kù)

# rpm -qa  grep mariadb
# rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64

下載YUM庫(kù)

# rpm wgethttp://dev.MySQL.com/get/mysql57-community-release-el7-7.noarch.rpm

安裝YUM庫(kù)

# rpm yum localinstall -ymysql57-community-release-el7-7.noarch.rpm

安裝數(shù)據(jù)庫(kù)

# rpm yum install -y mysql-community-server

啟動(dòng)MySQL服務(wù)

# rpm systemctl start mysqld.service

由于mysql5.7會(huì)自動(dòng)生成密碼，密碼文件存儲(chǔ)在/var/log/mysqld.log 中搜索password關(guān)鍵字即可找到密碼，登陸mysql

# mysql -uroot -p

重置root用戶密碼

mysql > alter user 'root'@'localhost' identified by '密碼';

重新以root用戶和剛設(shè)置的密碼進(jìn)行登錄即可。并授權(quán)用戶root使用密碼從任何主機(jī)連接到mysql服務(wù)器

mysql > grant all privileges on *.* to 'root'@'%' identifiedby '密碼' with grant option;
mysql > flush privileges;

或允許用戶root只能從ip為192.168.1.1的主機(jī)連接到mysql服務(wù)器

mysql > grant all privileges on *.* to 'root'@'192.168.1.1' identified by '密碼' with grant option;
mysql > flush privileges;

開(kāi)啟3306端口

# firewall-cmd --add-port=3306/tcp

以上就是Centos7.2下如何使用YUM來(lái)快速安裝MySQL5.7的方法介紹的詳細(xì)內(nèi)容，更多請(qǐng)關(guān)注php中文網(wǎng)其它相關(guān)文章！
