這篇我們來裝一下MySQL~
友情鏈接：http://downloads.mysql.com/archives/mysql-5.7/mysql-5.7.14.tar.gz
（我用的版本是5.6的啦，大同小異~）
1、指定安裝包的位置
[root@localhost~]# mv mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz /usr/local/
2、解壓
[root@localhost~]# tar zxvf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz
3、創建mysql用戶，事先存在的話可以先刪掉
[root@localhost mysql]# id mysql
uid=27(mysql) gid=27(mysql) groups=27(mysql)
[root@localhost mysql]# userdel -r mysql
[root@localhost mysql]# groupadd mysql
[root@localhost mysql]# useradd -g mysql mysql
[root@localhost mysql]# id mysql
uid=1002(mysql) gid=1002(mysql) groups=1002(mysql)
4、改變當前文件的所屬用戶所屬組
[root@localhost mysql]# chown -R mysql:mysql ./
5、執行安裝
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql
6、更改權限(使用/date/mysql存放數據)
[root@localhost mysql]# chown -R root:root ./
[root@localhost mysql]# chown -R mysql:mysql /data/mysql
[root@localhost mysql]# mkdir /data/mysql -p
[root@localhost mysql]# chown -R mysql:mysql /data/mysql
7、此時更改root的密碼會發生錯誤
[root@localhost mysql]# ./bin/mysqladmin -u root password 'root'
./bin/mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
8、啓動數據庫
[root@localhost mysql]# ./support-files/mysql.server start
Starting MySQL. SUCCESS!
9、更改root的連接密碼
[root@localhost mysql]# ./bin/mysqladmin -u root -h localhost.localdomain password 'root'
Warning: Using a password on the command line interface can be insecure.
9、連接數據庫
[root@localhost mysql]# ./bin/mysql -h 127.0.0.1 -uroot -proot
Warning: Using a password on the command line interface can be insecure.

Bye
10、添加mysqld服務
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# chkconfig --add mysqld
[root@localhost mysql]# chkconfig mysqld on
[root@localhost mysql]# service mysqld restart
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS!
[root@localhost mysql]# service mysqld status
SUCCESS! MySQL running (58914)
11、查看mysql相關進程
[root@localhost mysql]# ps -ef | grep mysql
root 58749 1 0 23:23 pts/0 00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/localhost.localdomain.pid
mysql 58914 58749 1 23:23 pts/0 00:00:00 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/var/lib/mysql --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/var/log/mariadb/mariadb.log --pid-file=/var/lib/mysql/localhost.localdomain.pid --socket=/var/lib/mysql/mysql.sock
root 58974 12939 0 23:23 pts/0 00:00:00 grep --color=auto mysql
12、查看mysql端口號
[root@localhost mysql]# netstat -tupln|grep mysql
tcp6 0 0 :::3306 :::* LISTEN 58914/mysqd
13、登陸數據庫
[root@localhost php]# mysql -uroot -proot
Welcome to the MariaDB monitor. Commands end with ; or \g.

14、查看數據庫
MySQL [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
+--------------------+
4 rows in set (0.11 sec)
完成啦~
