Linux安装MySQL 5.7

Linux安装MySQL 5.7

1、上传到/usr/local , 解压并重命名 为mysql

tar -zxvf  mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz  
​
mv  mysql-5.7.26-linux-glibc2.12-x86_64  mysql

  

2、创建mysql用户,并授予权限

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

  

3、安装MySQL

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

 

3.1随机密码为最后一行,一定要复制出来

 

4、修改配置文件 /etc/my.cnf (一般系统自带该文件,没有就手动创建)

vi /etc/my.cnf

 

[mysqld]
port=3306
datadir=/usr/local/mysql/data
socket=/usr/local/mysql/mysql.sock
user=mysql
max_connections=100
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
 
#忽略大小写
lower_case_table_names=1
 
#设置编码
character-set-server=utf8
collation-server=utf8_general_ci
 
#IP绑定
#bind-address=192.168.8.100
 
 
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
 
 
 
#客户端连接设置
[client]
# 和上面要相同才行
socket=/usr/local/mysql/mysql.sock
 
default-character-set=utf8

5、开启mysql服务

./support-files/mysql.server start

 

6、将mysql进程放入系统进程中

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

7、重启MySQL

service mysqld restart

 

8、设置MySQL环境变量

vim /etc/profile
​
export PATH=$PATH:/usr/local/mysql/bin
​
source /etc/profile

 

9、登陆MySQL(使用随机密码)

mysql -u root -p

 

10、修改密码(将密码修改成root)

alter user 'root'@'localhost' identified by 'root' ;

 

11、设置远程连接

use mysql;
​
update user set user.Host='%' where user.User='root';
​
flush privileges;

 

12、开放端口

# 1、查看暴露的端口号
iptables-save
# 2、开放端口号
firewall-cmd --zone=public --add-port=3306/tcp --permanent
# 3、重新加载
firewall-cmd --reload
