Linux系统mysql免安装版配置指南

1.下载（/usr/local目录）

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz

2.解压

tar -zvxf  mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz

3.创建目录

mv mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz mysql

mkdir /usr/local/mysql/data

4.创建用户和组

groupadd mysql

useradd -r -s /sbin/nologin -g mysql -d /usr/local/mysql mysql

5.更改权限

chown -R mysql:mysql /usr/local/mysql

6.安装

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

记住临时密码

如出现

则

ununtu系统:apt-get install libaio1 libaio-dev

centos系统:yum install libaio  yum -y install numactl

7.添加配置文件

vim /etc/my.cnf

[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
user=mysql
port=3306
character_set_server=utf8
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/usr/local/mysql/data/error.log
pid-file=/usr/local/mysql/data/mysqld.pid
tmpdir=/tmp

　　

8.设置为服务

cp  /usr/local/mysql/support-files/mysql.server  /etc/init.d/mysqld

修改配置

vim /etc/init.d/mysql.d

basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
mysqld_pid_file_path=/usr/local/mysql/data/mysqld_pid

启动mysql-service

cd /etc/init.d

./mysqld start

ubuntu

centos

成功后即可作为服务启动

service mysqld start/status/stop

9.客户端连接

./usr/local/mysql/bin/mysql -uroot -p

输入临时密码

centos系统可能会出现

执行yum -y install libncurses*

10.设置密码

set password for 'root'@localhost=password('root123');

flush privileges

11.开启root用户远程登录

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

flush privileges;

12.mysql程序目录配置到环境变量

vim /etc/profile

在底部新增

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

source /etc/profile

即可在任意路径登录mysql
