centos 5.8 64位系统安装 mysql5.6

        mysql5.5以上的版本编译需要 cmake

        1 、安装cmake

          wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz

          tar -zxvf cmake-2.8.10.2.tar.gz

          cd cmake-2.8.10.2

          ./configure

          make

          make install

          make clean

          到此 cmake安装完毕

        2 、安装 mysql

           1 下载mysql 

             官方下载地址  http://dev.mysql.com/downloads/mysql

              选择Source Code  

              我下载的是 Generic Linux (Architecture Independent), Compressed TAR Archive 这个版本(当前的版本是5.6.26)

              把下载好的文件上传到linux服务器

              或者直接 wget  http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.26.tar.gz

           2  检查是否已经安装了mysql   

        rpm -qa | grep mysql  (如果已经安装了需先卸载)  

        rpm -e --nodeps mysql-libs-5.1.61-4.el6.x86_64  (卸载mysql 卸载版本名称以实际的为准)

           3 安装mysql

             

          yum -y install make gcc-c++ bison-devel  ncurses-devel  //安装mysql所需要的依赖包
          groupadd mysql （增加mysql用户组）

          useradd -g mysql -s /sbin/nologin mysql  (增加mysql用户 不允许直接登录)

          tar -zxvf mysql-5.6.26.tar.gz

          cd mysql-5.6.26

          cmake . 
          -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
          -DMYSQL_DATADIR=/usr/local/mysql/data
          -DDEFAULT_CHARSET=utf8
          -DDEFAULT_COLLATION=utf8_general_ci
          -DEXTRA_CHARSETS=all 
          -DENABLED_LOCAL_INFILE=1   (cmake 编译mysql)
     
          make
          make install
          make clean
          chown -R mysql:mysql /usr/local/mysql

          chmod 755 /usr/local/mysql/scripts/mysql_install_db (赋给文件执行权限)

          /usr/local/mysql/scripts/mysql_install_db  --user=mysql  --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

          cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

          chmod 755 /etc/init.d/mysqld

          chkconfig --add mysqld

          chkconfig mysqld on
          
          编辑 /etc/init.d/my.cnf //mysql的配置文件写入如下内容 根据实际情况修改

          service mysqld restart

          添加到环境变量

          vi  /etc/profile

          添加如下代码 export PATH="$PATH:/usr/local/mysql/bin"

          source  /etc/profile

          登录mysql

          mysql -uroot -p  //登陆mysql  第一次登陆的时候不需要输入密码

          use mysql;

          delete from user where User=''; //删除用户名为空的用户

          UPDATE user SET password=PASSWORD("123456") WHERE user='root'; //修改root用户的密码

 
         mysql增加用户的命令

         grant all privileges on db_test.* to db_user@"%" identified by '123456' with grant option;

         这样就为 数据库 db_test 增加了一个  db_user的用户操作的权限 默认密码为  123456

         flush privileges;//刷新权限
         
         重启服务器，看mysql是否随着开机启动
