MySQL5.7 压缩包安装_mysql-5.7.37-linux 百度云

一、压缩包下载

压缩包下载路径：https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz

二、安装

2.1、解压缩

tar -zxvf mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz

2.2、创建安装目录

mkdir /usr/local/mysql

将解压后的文件夹拷贝至安装目录/usr/lcoal/mysql/,并重命名为mysql-5.7

mv mysql-5.7.37-linux-glibc2.12-x86_64 /usr/local/mysql/mysql-5.7

2.3、创建相关目录

mkdir /usr/local/mysql/mysql-5.7/data
mkdir /usr/local/mysql/mysql-5.7/log
touch /usr/local/mysql/mysql-5.7/log/mysqld.log

2.4、创建linux用户

su root
groupadd mysql #添加mysql组
useradd -r -g mysql mysql #添加mysql用户

2.5、更改文件归属

chown -R mysql /usr/local/mysql/mysql-5.7
chgrp -R mysql /usr/local/mysql/mysql-5.7

2.6、初始化MySQL

cd /usr/local/mysql/mysql-5.7
 
bin/mysqld --user=mysql --basedir=/usr/local/mysql/mysql-5.7/ --datadir=/usr/local/mysql/mysql-5.7/data --initialize

输出如下信息，会生成一个临时登录密码

 root@ubuntu:/usr/local/mysql/mysql-5.7# bin/mysqld --user=mysql --basedir=/usr/local/mysql/mysql-5.7/ --datadir=/usr/local/mysql/mysql-5.7/data --initialize

三、配置MySQL

3.1、修改配置文件

vim /etc/my.cnf

添加如下内容

[mysqld]
datadir=/usr/local/mysql/mysql-5.7/data
basedir=/usr/local/mysql/mysql-5.7
socket=/tmp/mysqld.sock
user=mysql
port=3306
character-set-server=utf8
skip-grant-tables
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
 
[client]
socket=/tmp/mysqld.sock
 

3.2、启动MySQL

cd /usr/local/mysql/mysql-5.7/support-files
sh mysql.server start

查看MySQL服务是否启动成功

sh support-files/mysql.server status
 
 
 * MySQL running (6787)
 

3.3、配置环境变量

vim /etc/profile

添加如下内容

export PATH=$PATH:/usr/local/mysql/mysql-5.7/bin

使配置生效

source /etc/profile

3.4、允许root账号远程访问

先本地登录mysql，查询权限

use mysql;
select  User,authentication_string,Host from user;

mysql> select  User,authentication_string,Host from user;
+---------------+-------------------------------------------+-----------+
| User          | authentication_string                     | Host      |
+---------------+-------------------------------------------+-----------+
| root          | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | localhost |
| mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | localhost |
| mysql.sys     | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | localhost |

设置权限

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root'
flush privileges; 

3.5、修改登录密码

set password for root@'%'=password('123456');
flush privileges; 

四、安装过程中的问题及解决办法

4.1、初始化报错

mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

解决办法：

yum install -y libaio.so.1

yum install -y libaio

4.2、修改权限报错

mysql> grant all on cactidb.* to dbuser@'localhost' identified by '123';

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

解决办法：

先输入 flush privileges; 刷新一下权限表，再重新执行grant命令，就成功了
