       參考別人的經驗，加上自己的理解，完成下面的動作。

============================== 


【原始碼安裝 mysql-5.6.10】

(1)解壓 mysql 原始碼 

?
1
2
[root@Betty Me_wget]# tar zxvf mysql-5.6.10.tar.gz
[root@Betty Me_wget]# cd mysql-5.6.10


(2)建立 mysql 的安裝目錄及資料庫存放目錄 

?
1
2
[root@Betty mysql-5.6.10]# mkdir -p /usr/local/mysql
[root@Betty mysql-5.6.10]# mkdir -p /usr/local/mysql/data


(3)建立 mysql 使用者及使用者組

[root@Betty mysql-5.6.10]# groupadd mysql
groupadd: group mysql exists
[root@Betty mysql-5.6.10]# useradd -r -g mysql mysql
useradd: user mysql exists
[root@Betty mysql-5.6.10]#

因為我之前已經安裝過一次，所以上面說使用者組和使用者已存在。 

(4)安裝 mysql 

引數說明： 

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql    //安裝目錄 
-DINSTALL_DATADIR=/usr/local/mysql/data     //資料庫存放目錄 
-DDEFAULT_CHARSET=utf8                    　　      //使用utf8字元 
-DDEFAULT_COLLATION=utf8_general_ci          //校驗字元 
-DEXTRA_CHARSETS=all                        　         //安裝所有擴充套件字符集 
-DENABLED_LOCAL_INFILE=1                    　     //允許從本地匯入資料 

執行 cmake 命令。

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
 
 
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
 
 
  ./bin/mysqladmin -u root password `new-password`
  ./bin/mysqladmin -u root -h Betty password `new-password`
 
 
Alternatively you can run:
 
 
  ./bin/mysql_secure_installation
 
 
which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.
 
 
See the manual for more instructions.
 
 
You can start the MySQL daemon with:
 
 
  cd . ; ./bin/mysqld_safe &
 
 
You can test the MySQL daemon with mysql-test-run.pl
 
 
  cd mysql-test ; perl mysql-test-run.pl
 
 
Please report any problems with the ./bin/mysqlbug script!
 
 
The latest information about MySQL is available on the web at
 
 
  http://www.mysql.com
 
 
Support MySQL by buying support/licenses at http://shop.mysql.com
 
 
New default config file was created as ./my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
 
 
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server
