linux通过二进制包安装mysql

 

f将mysql二进制包传到linux服务器上/usr/local目录下

tar -zvxf mysql-5.7.27-linux-glibc2.12-x86_64.tar.gz mysql

更改用户用户和组

chown -R mysql:mysql mysql/

cd mysql/support-files
touch my_default.cnf
vim my_default.cnf

复制以下内容到文件中：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL

返回上层目录中，初始化mysql

cd ../

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

如果报出权限不够，可以在/usr/local/mysql目录下手动新建一个data目录 mkdir data

复制my_default.cnf和mysql.server文件到对应目录

cp -a support-files/my_default.cnf /etc/my.cnf

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

启动mysql

bin/mysqld_safe --user=mysql

或者将mysql的安装路径配置到系统路径

vim /etc/profile

添加以下代码

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

source /etc/profile刷新

 

启动mysql

service mysqld start

进入mysql客户端

mysql -u root -p

输入初始化时出现的密码

若在这过程中有mysqld.sock错误，很大可能是my.cnf中socket配置的路径不存在或者权限不够，这时候手动创建该路径并分配权限即可

mkdir /var/run/mysqld
chmod -R 777 /var/run/mysqld

修改密码

SET PASSWORD = PASSWORD('xxxx');

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

 

如果遇到下列类似错误：

Access denied for user 'root'@'localhost' (using password:YES)

可以编辑/etc/my.cnf文件，在[mysqld]下添加跳过验证

然后重启mysql服务，就可以跳过密码登陆mysql了
