MySQL 5.7.22 二進制安裝

一、到官網下載mysql-5.7.22二進制包

二、創建mysql用戶：

useradd mysql -s /sbin/nologin -M

三、解壓mysql-5.7.22-el7-x86_64.tar.gz ：

tar xf mysql-5.7.22-el7-x86_64.tar.gz && mv mysql-5.7.22-el7-x86_64.tar.gz /opt/mysql

四、創建相關目錄：

cd /opt/mysql mkdir {data,logs,etc} mkidr logs/binlog

五、修改權限：

cd /opt/ && chown -R mysql.mysql mysql

六、初始化數據庫：

cd /opt/mysql ./bin/mysqld --initialize --user=mysql --basedir=/opt/mysql --datadir=/opt/mysql/data記住最后提示的密碼

七、修改my.cnf文件：

echo > /etc/my.cnf vi my.cnf 加入文檔最后的內容

八、配置mysql服務：

cd /opt/mysql && cp support-files/mysql.server /etc/init.d/mysqld 修改權限chmod +x /etc/init.d/mysqld 編輯mysqld加入basedir=/opt/mysql datadir=/opt/mysql/datachkconfig --add mysqld

九、啟動mysql服務：

service mysqld start 此時會報日志錯誤：Starting MySQL.2018-07-26T14:24:53.192088Z mysqld_safe error: log-error set to '/opt/mysql/logs/mysql-error.log', however file don't exists. Create writable for user 'mysql'.ERROR! The server quit without updating PID file (/opt/mysql/data/mysql.pid).原因是找不到logs下的mysql-error.log文件我們手動創建一個 touch /opt/mysql/logs/mysql-error.log&&chown mysql.mysql mysql-error.log再執行service mysqld start 即可

十、配置環境變量：

cd &&vi .bash_profile 在PATH后加上/opt/mysql/bin，保存退出執行source .bash_profile

十一、登錄數據庫，修改密碼：

啟動服務后，執行mysql -uroot -p 輸入初始化時的密碼執行show databases; 會報錯ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.執行set PASSWORD=PASSWORD('123456'); flush privileges 修改密碼退出后用新密碼可以重新登錄

至此，Mysql-5.7.22二進制方式安裝完成
