MySQL 5.7手动安装步骤

MySQL 5.7手动安装步骤

一，下载

1.1 下载地址

https://dev.mysql.com/downloads/mysql/

download :https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz

1.2 mysql主配置信息

内存：2-4G

二，安装配置

2.1 解压安装文件到/usr/local/

cd /usr/local/

tar xf mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz -C /usr/local

mkdir /usr/local/mysql

unlink /usr/local/mysql

ln -fs /usr/local/mysql-5.7.29-linux-glibc2.12-x86_64 /usr/local/mysql

2.2 创建数据目录&mysql用户

mkdir -p /data/mysql/3306/{data,binlog,relaylog,dblog,tmp}

touch /data/mysql/3306/dblog/error.log

useradd mysql

chown -R mysql.mysql /data/mysql/3306

2.3 创建配置文件到

vim /data/mysql/3306/my.cnf

[client]

port = 3306

socket = /data/mysql/3306/mysql.sock

[mysql]

2.4 初使化

/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/3306/my.cnf --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/3306/data/

2.5 启动服务

/usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysql/3306/my.cnf --user=mysql &

2.6 初始化密码

这种安装是无密码本机登录

/usr/local/mysql/bin/mysql -uroot -S /data/mysql/3306/mysql.sock

ln -fs /data/mysql/3306/mysql.sock /tmp

就不用每次 -S /data/mysql/3306/mysql.sock

其他安装方式需要输入密码

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

2.7 MySQL5.7 root开放远程连接

例如，你想使用账号username 使用密码 password 从任何主机连接到mysql服务器的话。

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

FLUSH  PRIVILEGES;

别忘了执行语句 FLUSH RIVILEGES 使修改生效
