centos5.6下源码安装mysql

install_mysql_centos5.6
总结：其实事情很简单，答案一直就在跟前，我们却总很容易将他们忽视掉，用心想，静静地看，答案就在那里。

1. download mysql-5.1.56.tar.gz to /opt/src

2. $cd /opt/src

3. $tar -zxvf mysql-5.1.56.tar.gz

4. $cd mysql-5.1.56

5. $mkdir -p /opt/apps/mysql-5.1.56 /opt/etc/mysql /opt/var/mysql
                /opt/tmp/mysql

6. $./configure --prefix=/opt/apps/mysql-5.1.56/   \
        --sysconfdir=/opt/etc/mysql/          \
        --localstatedir=/opt/var/mysql/  \
        --with-unix-socket-path=/opt/tmp/mysql/mysql.sock \
        --with-tcp-port=3306 \
        --with-charset=utf8 \
        --with-extra-charsets=gb2312,gbk

7. $make

8. $make install

9. $su - root

10.$sudo cp /opt/src/support-files/my-medium.cnf /etc/my.cnf

11.$sudo groupadd mysql

12.$sudo useradd -g mysql mysql

13.$sudo chown -R mysql:mysql /opt/var/mysql

14.$sudo chown -R mysql:mysql /opt/tmp/mysql/

14.$ln -s /opt/apps/mysql-5.1.56 /opt/apps/mysql

15.$sudo vim /etc/my.cnf
        instead skip-locking by #skip-locking
      add:
            skip-external-locking

16.$sudo ./mysql/bin/mysql_install_db --user=mysql
        note:
            generate the initial privileges or grant tables

17. 启动mysql服务
    $sudo /opt/apps/mysql/bin/mysqld_safe &
        note:
            starts the mysqld_safe daemon, which will in turn start the MySQL server mysqld.
            If the mysqld daemon crashes,mysqld_safe will restart it.
            The ampersand instructs the shell to run the daemon in the background.

18.关闭mysql服务
    $/opt/apps/mysql/bin/mysqladmin -u root shutdown

19.设置root密码
    $/opt/apps/mysql/bin/mysqladmin -u root password 'new-password'

20.设置密码后，关闭服务
    $/opt/apps/mysql/bin/mysqladmin -uroot -ppassword shutdown
    或者
    $/opt/apps/mysql/bin/mysqladmin -u root -p shutdown

21. 登录mysql
    $mysql -u root -p
    或者
    $mysql -uroot -ppasswd

22.设置开机启动
    $su - root
    #cp /opt/src/mysql-5.1.56/support-files/mysql.server /etc/init.d/mysql
            注：place the startup file for the server in the server's initial daemons directory
                with the name mysql.
    #chmod +x /etc/init.d/mysql
    #chkconfig --add mysql 
            注：set the run level of the service for startup and shutdown

23. 至此可以通过相关设置
    #chkconfig mysql off         //设置不随机启动
    #chkconfig mysql on          //重新随即启动

24.启动mysql也可以更加方便
    #/etc/init.d/mysql start       //启动
    #/etc/init.d/mysql stop       //关闭
    #/etc/init.d/mysql restart
    或者
    #service mysql start

1. error: No curses/termcap library found
         sudo yum install ncurses-devel
        curses构成了一个工作在底层终端代码之上的封装，并向用户提供了一个灵活高效的API
        （Application Programming Interface 应用程序接口）。它提供了移动光标，
        建立窗口，产生颜色，处理鼠标操作等功能。使程序员编写应用程序不需要关心那些底层的
        终端操作。
        ncurses是最早的System V Release 4.0 (SVr4)中 CURSES的一个克隆。这是一个
        可自由配置的库，完全兼容旧版本的curses。简而言之，它是一个管理应用程序在字符终
        端显示的函数库。当后面提到curses的时候，同时也可以和NCURSES互换。

2. exec: g++: not found
        sudo yum install gcc-c++

3.  错误：对 C++ 内建类型 ‘bool’ 的重声明
        重新./configure一下，然后再make就好了。

4.  '--skip-locking' is deprecated and will be removed in a future release.             Please use '--skip-external-locking' instead.、

5.  执行脚本
    $sudo ./mysql/bin/mysql_install_db --user=mysql
    时，出现的话，你看过吗，却傻巴垃圾的去问人，去google.
    Installing MySQL system tables...

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:

/opt/apps/mysql-5.1.56/bin/mysqladmin -u root password 'new-password'
/opt/apps/mysql-5.1.56/bin/mysqladmin -u root -h net.yy.com password 'new-password'

Alternatively you can run:
/opt/apps/mysql-5.1.56/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 /opt/apps/mysql-5.1.56 ; /opt/apps/mysql-5.1.56/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /opt/apps/mysql-5.1.56/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /opt/apps/mysql-5.1.56/bin/mysqlbug script!
