   $ make && make install
   # 没有太大的原因这里应该会成功的
   

6. 配置和运行

   • 配置 mysql 启动文件

     $ cd /usr/local/mysql
     $ cp support-files/mysql.server /etc/init.d/mysqld
     $ cp support-files/my-default.cnf /etc/my.cnf
     $ cd scripts
     $ ./mysql_install_db --user=mysql --basedir=/usr/local/mysql/
     

   • 配置系统变量

     $ echo "PATH=$PATH:/usr/local/mysql/bin/" >> /etc/profile
     

$ source /etc/profile

“`

• 修改默认的 /etc/my.cnf

  [mysqld]user = mysql
  port = 3306
  socket = /tmp/mysql.sock
  basedir = /usr/local/mysql
  datadir = /usr/local/mysql/data
  open_files_limit = 10240[mysqld_safe]
  log-error=/usr/local/mysql/data/mysql_oldboy.err
  pid-file=/usr/local/mysql/data/mysqld.pidsql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
  

• 启动

  # 启动 mysql
  $ service mysqld start
  

• 设置root密码

  $ mysql_secure_installation
  NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
        SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!In order to log into MySQL to secure it, we'll need the current
  password for the root user.  If you've just installed MySQL, and
  you haven't set the root password yet, the password will be blank,
  so you should just press enter here.Enter current password for root (enter for none):
  OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MySQL
  root user without the proper authorisation.
  # 设置 root 密码
  Set root password? [Y/n] Y
  New password:
  Re-enter new password:
  Password updated successfully!
  Reloading privilege tables..
   ... Success!By default, a MySQL installation has an anonymous user, allowing anyone
  to log into MySQL without having to have a user account created for
  them.  This is intended only for testing, and to make the installation
  go a bit smoother.  You should remove them before moving into a
  production environment.
  # 删除 匿名用户
  Remove anonymous users? [Y/n] Y
   ... Success!Normally, root should only be allowed to connect from 'localhost'.  This
  ensures that someone cannot guess at the root password from the network.
  # 设置 root 只能来自本机登录
  Disallow root login remotely? [Y/n] Y
   ... Success!By default, MySQL comes with a database named 'test' that anyone can
  access.  This is also intended only for testing, and should be removed
  before moving into a production environment.
  # 删除测试数据库
  Remove test database and access to it? [Y/n] Y
   - Dropping test database...
   ... Success!
   - Removing privileges on test database...
   ... Success!Reloading the privilege tables will ensure that all changes made so far
  will take effect immediately.
  # 重新加载配置
  Reload privilege tables now? [Y/n] Y
   ... Success!All done!  If you've completed all of the above steps, your MySQL
  installation should now be secure.Thanks for using MySQL!Cleaning up...

• 设置开机自启动

  $ /sbin/chkconfig mysqld on
  

完成所有的安装和启动,重启一下试试 mysql 是否能正常自动启动。如果可以 mysql 就安装完成了
