MySQL5.7.22二进制安装-创新互联
MySQL 5.7.22 二进制安装
一、到官网下载mysql-5.7.22二进制包
二、创建mysql用户：
useradd mysql -s /sbin/nologin -M三、解压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、创建相关目录：
cd /opt/mysql mkdir {data,logs,etc} mkidr logs/binlog五、修改权限：
cd /opt/ && chown -R mysql.mysql mysql六、初始化数据库：
cd /opt/mysql
./bin/mysqld --initialize --user=mysql --basedir=/opt/mysql --datadir=/opt/mysql/data
记住最后提示的密码七、修改my.cnf文件：
echo > /etc/my.cnf vi my.cnf 加入文档最后的内容八、配置mysql服务：
cd /opt/mysql && cp support-files/mysql.server /etc/init.d/mysqld
修改权限chmod +x /etc/init.d/mysqld
编辑mysqld加入basedir=/opt/mysql datadir=/opt/mysql/data
chkconfig --add mysqld九、启动mysql服务：
service mysqld start
此时会报日志错误：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
我们手动创建一个
touch /opt/mysql/logs/mysql-error.log&&chown mysql.mysql mysql-error.log
再执行service mysqld start 即可十、配置环境变量：
cd &&vi .bash_profile 在PATH后加上/opt/mysql/bin，保存退出
执行source .bash_profile十一、登录数据库，修改密码：
启动服务后，执行mysql -uroot -p 输入初始化时的密码
执行show databases; 会报错ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
执行set PASSWORD=PASSWORD('123456'); flush privileges 修改密码
退出后用新密码可以重新登录至此，Mysql-5.7.22二进制方式安装完成
