第一次启动mysql,会自动生成一个随机密码,可在/var/log/mysqld.log中查看。

测试:
## 启动 mysql 服务[root-mysql ~]# systemctl start mysqld## 关闭[root-mysql ~]# systemctl stop mysqld## 重启[root-mysql ~]# systemctl restart mysqld## 状态查看[root-mysql ~]# systemctl status mysqld## 设置开机自启[root-mysql ~]# systemctl enable mysqld
## rpm方式重要文件路径说明主要文件默认路径如下:配置文件路径:/etc/my.cnf数据存储目录:/var/lib/mysql错误日志存储路径:/var/log/mysqld.logSocket文件路径:/var/lib/mysql/mysql.sock参数可以通过/etc/my.cnf参数配置文件查看和自定义。
[root-mysql mysql-tar]# tar -zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
[root-mysql mysql-tar]# mkdir /usr/local/mysql
[root-mysql ~]# mv mysql-5.7.18-linux-glibc2.5-x86_64/* /usr/local/mysql/
[root-mysql mysql]# mkdir /usr/local/mysql/data[root-mysql mysql]# [root-mysql mysql]# mkdir /usr/local/mysql/log[root-mysql mysql]# [root-mysql mysql]# touch /usr/local/mysql/log/mysqld.log[root-mysql mysql]# [root-mysql mysql]#

[root-mysql mysql]# chown -R mysql /usr/local/mysql/[root-mysql mysql]# chgrp -R mysql /usr/local/mysql/
或者使用:
[root-mysql mysql]# chown -R mysql:mysql /usr/local/mysql
[root-mysql mysql]# ./bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize
[root-mysql mysql]# vi /etc/my.cnf

[root-mysql mysql]# cd support-files/[root-mysql support-files]# sh mysql.server startStarting MySQL. SUCCESS! [root-mysql support-files]#
查看MySQL服务是否启动成功
[root-mysql support-files]# sh mysql.server status SUCCESS! MySQL running (2294)[root-mysql support-files]#
[root-mysql support-files]# vi /etc/profile
export PATH=$PATH:/usr/local/mysql/bin
使配置生效
[root-mysql support-files]# source /etc/profile
[root-mysql support-files]# mysql -u root -p
修改mysql数据库密码报错:
ERROR 1290 (HY000): The MySQL Server is running with the --skip-grant-tables option so it cannot execute this statement.
解决:先刷新权限表
