mysql安裝rpm方式
rpm -qa | grep mysql
卸載自帶的mysql
rpm -e --nodeps *
解壓mysql
tar -xvf mysql-5.7.18-1.el7.x86_64.rpm-bundle.tar
安裝順序
mysql-community-common-5.7.18-1.el7.x86_64.rpm
mysql-community-libs-5.7.18-1.el7.x86_64.rpm（依賴於common）
mysql-community-client-5.7.18-1.el7.x86_64.rpm（依賴於libs）
mysql-community-server-5.7.18-1.el7.x86_64.rpm
mysql-community-devel-5.7.18-1.el7.x86_64.rpm（MySQL頭文件和庫文件）
mysql-community-libs-compat-5.7.18-1.el7.x86_64.rpm
執行如下命令：
rpm -ivh mysql-community-common-5.7.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.18-1.el7.x86_64.rpm
如果報錯則執行
yum remove mariadb-libs
強制卸載
rpm -e --nodeps mariadb-libs-5.5.41-2.el7_0.x86_64
啟動mysql命令
systemctl start mysqld
查看是否啟動成功：
systemctl status mysqld.service
重置mysql的密碼
vi /etc/my.cnf
在文件尾部添加
character_set_server=utf8 --設置字符集
init_connect='SET NAMES utf8'
lower_case_table_names=1 --忽略大小寫
skip-grant-tables=1 --無密碼方式進入mysql
重啟 mysqld 服務命令
systemctl restart mysqld
然後輸入 mysql -u root
use mysql;
update user set authentication_string = password('***'),
password_expired='N',password_last_changed = now() where user ='root'; FLUSH PRIVILEGES;
退出數據庫
exit
把添加的配置文件的一行刪掉，光標移動到最下面，按“i”鍵，刪除skip-grant-tables=1
登錄MYSQL
mysql -u root -p**
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '**' WITH GRANT OPTION; --絕對不能少的一步;
CREATE DATABASE `**` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
