1、下载MySQL安装包(https://dev.mysql.com/downloads/mysql/

2、上传mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz文件至/usr/local下

3、解压安装包至/usr/local下

tar -zxvf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz

4、重命名文件夹为mysql

mv mysql-5.7.25-linux-glibc2.12-x86_64 mysql

5、创建数据文件目录

cd /usr/local/mysql
mkdir data

6、创建用户组和用户

groupadd mysql
useradd -g mysql mysql

7、修改用户权限

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

8、初始化数据库

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

结尾处为初始密码,将密码复制出来记在记事本上。

若报如下错:

./mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object

file: No such file or directory

则执行:

yum remove libnuma.so.1;

yum -y install numactl.x86_64;

 

9、将mysql加入服务

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

10、配置my.cnf

搜索my.cnf

find / -name my.cnf

找到后复制到 /etc/my.cnf

并进行如下编辑,若找不到则在/etc下手动编辑一个 

[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
#不区分大小写
lower_case_table_names = 1
#不开启sql严格模式
sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
log-error=/var/log/mysqld.log
pid-file=/usr/local/mysql/data/mysqld.pid

11、添加开机自启动

vim /etc/init.d/mysql

编辑其中两个属性如下 :

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

开机自启:

chkconfig --add mysql
chkconfig mysql on

启动mysql:

service mysql stop
service mysql start

查询列表:

chkconfig | grep -i mysql

如果看到mysql的服务,并且3,4,5都是on的话则成功,如果是off,则执行

chkconfig --level 345 mysql on

重启电脑:

reboot

验证:

netstat -na | grep 3306

连接mysql并修改默认密码:

cd /usr/local/mysql/bin
./mysql -uroot -p
然后输入刚才记下来的默认密码,登录后修改默认密码
alter user 'root'@'localhost' identified by '新密码';
flush privileges; ---刷新权限,之后退出重新登录

12、设置远程连接权限

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