安裝環境：centos6

1、下載

2、解壓縮到/usr/local/

[root@localhost local]# cd /usr/local/soft/
[root@localhost soft]# tar zvxf mysql-5.7.10-linux-glibc2.5-i686.tar.gz -C /usr/local
[root@localhost soft]# cd ..
[root@localhost local]# mv /usr/local/mysql-5.7.10-linux-glibc2.5-i686 /usr/local/mysql

3、在mysql下面建立data資料庫檔案目錄

[root@localhost local]# mkdir /usr/local/mysql/data

4、建立mysql的使用者組和使用者，並對mysql目錄設定使用者組和使用者

[root@localhost local]# groupadd mysql
[root@localhost local]# useradd mysql -g mysql
[root@localhost local]# cd mysql
[root@localhost mysql]# pwd
/usr/local/mysql
[root@localhost mysql]# chown -R mysql .  
[root@localhost
 
 mysql]# chgrp -R mysql .   

5、初始化mysql並啟動mysql服務

[[email protected] mysql]# cd /usr/local/mysql/bin
[[email protected] bin]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
2016-01-09 12:00:28 [WARNING] mysql_install_db is deprecated. Please consider switching to
 
 mysqld --initialize
2016-01-09 12:00:33 [WARNING] The bootstrap log isn't empty:
2016-01-09 12:00:33 [WARNING] 2016-01-09T04:00:29.262989Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead
2016-01-09T04:00:29.264643Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)
2016-01-09T04:00:29.264653Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

報警可以忽略

6、修改my.cnf

[root@localhost mysql]# vim /etc/my.cnf
# 將datadir=/var/lib/mysql修改為實際的安裝路徑 如 datadir=/usr/local/mysql/data
[root@localhost mysql]# vim /etc/selinux/config
# 把SELINUX=enforcing改為SELINUX=disabled後存檔退出重啟機器

7、建立sock檔案目錄

[root@localhost mysql]# mkdir -p /var/lib/mysql
[root@localhost mysql]# chown mysql:mysql /var/lib/mysql

8、 建立sock檔案軟連線

[root@localhost bin]# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

9、啟動mysql

[root@localhost bin]# cd /usr/local/mysql/support-files
[root@localhost support-files]# ./mysql.server start

10、配置mysql環境變數

[[email protected] bin]# vim /etc/profile
export MYSQL_HOME=/usr/local/mysql
export PATH=\$PATH:$MYSQL_HOME/bin

11、獲取mysql初始化密碼，登入mysql，修改密碼

[[email protected] ~]# cat /root/.mysql_secret
[[email protected] ~]# cd /usr/local/mysql/bin
[[email protected] bin]# ./mysql -uroot -p:5ul#d6dkcwX

mysql: [Warning] Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql>

• 11.5、如上，顯示登入成功，可以執行mysql命令操作了！

12、改mysql的root密碼，新密碼在此為’root’

mysql> set password=password('root');
Query OK, 0 rows affected, 1 warning (0.00 sec)

13、設定遠端登入mysql。在Linux下為了安全，預設是不允許mysql本機以外的機器訪問mysql資料庫服務，因此需要重新授權root。

mysql> grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;
grant all privileges on *.* to 'root’@'centos1' identified by 'root' with grant option;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A


Database changed
mysql> select Host,User from user;
+-----------+-----------+
| Host      | User      |
+-----------+-----------+
| %         | root      |
| localhost | mysql.sys |
| localhost | root      |
+-----------+-----------+
3 rows in set (0.00 sec)

14、將mysql配置到服務並設定開機啟動

• 14.1、將mysql配置為服務mysql

[root@centos1 mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

• 14.2、將mysql服務設定為開機啟動

[root@centos1 mysql]# chkconfig mysql on

• 14.3、啟動mysql服務

[root@centos1 mysql]# service mysql start

15、報錯解決

• 15.1、如果遠端連不上，估計是防火牆的問題，關閉試試：

[root@centos1 mysql]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@centos1 mysql]# service iptables status
iptables: Firewall is not running.

• 15.2、解決報錯：mysqld_safe Directory ‘/var/lib/mysql’ for UNIX socket file don’t exists.

mkdir -p /var/lib/mysql
chown mysql:mysql /var/lib/mysql

• 15.3、解決報錯：Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
