1. 下载MySQL二进制包

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.xx-linux-glibc2.12-x86_64.tar.gz

2. 解压缩到/usr/local/mysql

tar -zxvf mysql-5.7.xx-linux-glibc2.12-x86_64.tar.gz -C /usr/local

mv /usr/local/mysql-5.7.xx-linux-glibc2.12-x86_64 /usr/local/mysql

3. 创建my.cnf配置文件

tee /etc/my.cnf <<-'EOF'

mysqld

datadir=/usr/local/mysql/data

port=3306

EOF

4. 初始化数据库

useradd mysql

cd /usr/local/mysql

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/mysql.pid --tmpdir=/tmp

5. 启动MySQL服务

/usr/local/mysql/support-files/mysql.server start

6. 设置root用户密码

grep 'temporary password' /usr/local/mysql/data/localhost.localdomain.err

hostname的值

localhost.localdomain

grep 'temporary password' /usr/local/mysql/data/xxx.err

7、使用临时密码登录MySQL，并更改root密码

/usr/local/mysql/bin/mysql -u root -pNewPassword

ALTER USER 'root'@'localhost' IDENTIFIED BY 'NewPassword';

ALTER USER 'root'@'%' IDENTIFIED BY 'NewPassword';

8、配置PATH

vi /etc/profile

export PATH="$PATH:/usr/local/mysql/bin:/usr/local/mysql/support-files"

9、常用运维方式

1、启动关闭

复制代码

mysql.server start/stop

2、没有了
