1. 從官網下載 mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz

# wget -c http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz

2. 建立mysql的使用者組/使用者, data目錄及其使用者目錄

# groupadd mysql
# useradd -g mysql -d /home/mysql mysql
# mkdir /home/mysql/data

3. 解壓安裝包並將解壓包裡的內容拷貝到mysql的安裝目錄/home/mysql

# tar -xzvf mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz
# cd mysql-5.7.9-linux-glibc2.5-x86_64 
# mv * /home/mysql

4. 初始化mysql資料庫

# cd /home/mysql
# ./bin/mysql_install_db --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data

2015-11-10 02:09:17 [WARNING] mysql_install_db is deprecated. Please consider switching to
 
 mysqld --initialize
2015-11-10 02:09:23 [WARNING] The bootstrap log isn't empty:
2015-11-10 02:09:23 [WARNING] 2015-11-10T10:09:18.114182Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead

2015-11
 
-10T10:09:18.129408Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

p.s. : mysql5.7新特性：由上面可以看出， mysql_install_db 已經不再推薦使用了，建議改成 mysqld --initialize 完成例項初始化。

# ./bin/mysqld --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data --initialize

改用 mysqld --initialize 後，如果 datadir 指向的目標目錄下已經有資料檔案, 會出現如下提示：

# ./mysqld --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data --initialize
2016-04-08T01:46:53.153530Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2016-04-08T01:46:53.155856Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting.
2016-04-08T01:46:53.155879Z 0 [ERROR] Aborting

由上可知， 我們需要清空mysql的data目錄， 執行清空命令如下：

# cd /home/mysql/data
# rm -fr *

然後重新執行初始化命令如下：

# ./bin/mysqld --user=mysql --basedir=/home/mysql --datadir=/home/mysql/data --initialize
2016-04-08T01:47:57.556677Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

2016-04-08T01:48:00.440904Z 1 [Note] A temporary password is generated for [email protected]: **mjT,#x_5sW

牢記上面的隨機密碼， 如上**mjT,#x_5sW, 下面我們修改密碼時需要用到。

5. 檢測下是否能啟動mysql服務

# cd /home/mysql
# ./support-files/mysql.server start
Starting MySQL.. SUCCESS! 

若改用了/home/mysql為mysql的安裝目錄basedir， 則在啟動服務時會出現如下錯誤：

# ./support-files/mysql.server start
./support-files/mysql.server: line 276: cd: /usr/local/mysql: No such file or directory
Starting MySQL ERROR! Couldn't find MySQL server (/usr/local/mysql/bin/mysqld_safe)

由上面可知mysql的tar.gz安裝包的預設安裝目錄為/usr/local/mysql， 這時候我們需要修改/support-files/mysql.server檔案的basedir和datadir目錄路徑為我們環境所在的mysql的basedir和datadir路徑， 如下：

# vim support-files/mysql.server
--------------------------
...
basedir=/home/mysql
datadir=/home/mysql/data
... 
--------------------------
# ./support-files/mysql.server start
Starting MySQL.. SUCCESS! 

6. 建立軟連結

# ln -s /home/mysql/bin/mysql /usr/bin/mysql

7. 建立配置檔案

將預設生成的my.cnf備份

# mv /etc/my.cnf /etc/my.cnf.bak

進入mysql的安裝目錄支援檔案目錄

# cd /home/mysql/support-files

拷貝配置檔案模板為新的mysql配置檔案,

# cp my-default.cnf /etc/my.cnf

可按需修改新的配置檔案選項， 不修改配置選項， mysql則按預設配置引數執行.
如下是我修改配置檔案/etc/my.cnf， 設定編碼為utf8以防亂碼

# vim /etc/my.cnf

[mysqld]

basedir = /home/mysql
datadir = /home/mysql/data

character_set_server=utf8
init_connect='SET NAMES utf8'


[client]
default-character-set=utf8

8. 配置mysql服務開機自動啟動

拷貝啟動檔案到/etc/init.d/下並重命令為mysqld

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

增加執行許可權

# chmod 755 /etc/init.d/mysqld

檢查自啟動項列表中沒有mysqld這個，如果沒有就新增mysqld：

# chkconfig --list mysqld
# chkconfig --add mysqld

設定MySQL在345等級自動啟動

# chkconfig --level 345 mysqld on

或用這個命令設定開機啟動：

# chkconfig mysqld on

9. mysql服務的啟動/重啟/停止

啟動mysql服務

# service mysqld start

重啟mysql服務

# service mysqld restart

停止mysql服務

# service mysqld stop

10. 初始化mysql使用者root的密碼

先將mysql服務停止

# service mysqld stop

進入mysql安裝目錄， 執行：

# cd /home/mysql
# ./bin/mysqld_safe --skip-grant-tables --skip-networking&
[1] 6225
[[email protected] mysql]# 151110 02:46:08 mysqld_safe Logging to '/home/mysql/data/localhost.localdomain.err'.
151110 02:46:08 mysqld_safe Starting mysqld daemon with databases from /home/mysql/data

另外開啟一個終端(p.s. 如果是ssh連線登入的, 另外建立一個ssh連線即可）， 執行操作如下：

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

到此， 設定完mysql使用者root的密碼且確保mysql編碼集是utf8, 注意上面， 新版本的mysql.user表裡的密碼欄位是authentication_string

快捷鍵ctrl + c停止# ./bin/mysqld_safe ...命令， 重新啟動mysql服務， 用新密碼連線mysql：

# service mysqld start
Starting MySQL SUCCESS!

咦？又要我改密碼， 我們通過mysqladmin來修改密碼， 先輸入原密碼， 再設定新密碼， 總算可以了吧！！！

# ./bin/mysqladmin -u root -p password

或直接：

mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

其中， **mjT,#x_5sW就是我們在使用mysqld --initialize時牢記下的隨機密碼

11. mysql遠端授權

格式如下：

mysql> grant all [privileges] on db_name.table_name to 'username'@'host' identified by 'password';

示例如下：

mysql> grant all privileges on *.* to 'root'@'%' identified by '123456';
Query OK, 0 rows affected, 1 warning (0.04 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> 

或用

mysql> grant all on *.* to 'root'@'%' identified by '123456';

到此， 完成了mysql的安裝 及配置！！！
