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
        記住最後提示的密碼

七、修改my.cnf文件：

        echo > /etc/my.cnf     vi my.cnf 加入文檔最後的內容

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/data
        chkconfig --add mysqld
 

九、啟動mysql服務：

        service mysqld start 
        此時會報日誌錯誤：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後加上/opt/mysql/bin，保存退出
        執行source .bash_profile

十一、登錄數據庫，修改密碼：

        啟動服務後，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
        退出後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
