mysql下载链接

本次演示版本为 mysql-5.7.28  如下图所示

将下载的压缩包上传至linux虚拟机内

解压当前亚索包 至 、/usr/local/下

tar -zxvf mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz

将名称改为mysql

mv mysql-5.7.28-linux-glibc2.12-x86_64 mysql

创建数据目录

cd mysql

mkdir data

创建用户组

groupadd mysql

useradd -r -g mysql mysql

赋予权限

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

修改mysql配置文件

vim /etc/my.cnf

修改去下

[mysqld]

bind-address=0.0.0.0

user=mysql

port=3306

basedir=/usr/local/mysql

datadir=/usr/local/mysql/data

socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

# Settings user and group are ignored when systemd is used.

# If you need to run mysqld under a different user or group,

# customize your systemd unit file for mariadb according to the

# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]

log-error=/var/log/mariadb/mariadb.log

pid-file=/var/run/mariadb/mariadb.pid

#

# include all files from the config directory

#

!includedir /etc/my.cnf.d

进去mysql的bin目录下

cd /usr/local/mysql/bin

初始化mysql

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

复制下初始密码

将mysql.server放置到/etc/init.d/mysql目录下

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

启动mysql

service mysql start

解决上述报错

mkdir /var/log/mariadb

touch /var/log/mariadb/mariadb.log

chown -R mysql /var/log/mariadb/

重启mysql

service mysql restart

解决无文件夹的问题 并赋予权限重启mysql

mkdir mysql

chown -R mysql /var/lib/mysql/

service mysql restart

启动成功 登录mysql

./mysql -u root -p

set password=password('XXXX');#设置自己的密码

grant all privileges on *.* to 'root'@'%' identified by 'root'; #赋予远程访问权限

flush privileges;#刷新权限

一个简单的mysql创建已经成功了，如有问题欢迎交流!
