一、到官網(wǎng)下載mysql-5.7.22二進(jìn)制包
二、創(chuàng)建mysql用戶：
重慶分公司
重慶分公司
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(chuàng)建相關(guān)目錄：
cd /opt/mysql mkdir {data,logs,etc} mkidr logs/binlog五、修改權(quán)限：
cd /opt/ && chown -R mysql.mysql mysql六、初始化數(shù)據(jù)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(nèi)容八、配置mysql服務(wù)：
cd /opt/mysql && cp support-files/mysql.server /etc/init.d/mysqld
修改權(quán)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(dòng)mysql服務(wù)：
service mysqld start
此時(shí)會(huì)報(bào)日志錯(cuò)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(dòng)創(chuàng)建一個(gè)
touch /opt/mysql/logs/mysql-error.log&&chown mysql.mysql mysql-error.log
再執(zhí)行service mysqld start 即可十、配置環(huán)境變量：
cd &&vi .bash_profile 在PATH后加上/opt/mysql/bin，保存退出
執(zhí)行source .bash_profile十一、登錄數(shù)據(jù)庫，修改密碼：
啟動(dòng)服務(wù)后，執(zhí)行mysql -uroot -p 輸入初始化時(shí)的密碼
執(zhí)行show databases; 會(huì)報(bào)錯(cuò)ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
執(zhí)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(jìn)制方式安裝完成
