linux 下mysql二进制文件（tar.gz）安装

  二进制文件（tar.gz）安装：
先创建用户和用户组
 su - root
groupadd mysql
useradd -g mysql mysql 解压二进制文件。
gunzip -c filename | tar -xf - 复制目录/home/mysql到/usr/local； 创建mysql许可表：
linux:/usr/local/mysql #scripts/mysql_install_db --user=mysql 设置二进制所有权，使之归root所有，并属于mysql所在管理组：
linux:/usr/local/mysql # chown -R root /usr/local/mysql
linux:/usr/local/mysql # chgrp -R mysql/usr/local/mysql 将数据目录的所有权设置为mysql管理用户：
linux:/usr/local/mysql # chown -R mysql /usr/local/mysql/data 启动服务器：
linux:/usr/local/mysql # bin/mysqld_safe --user=mysql & 登入：
linux:/usr/local/mysql # bin/mysql -u mysql mysql>show databases;
最初只有两个：test，information_schema；
以root身份登入则有四个。 运行命令bin/mysql -u root -p，此时将出现password:（要求输入密码），但默认情况下root用户没有密码，所以回车即可。此时将进入MySQL界面，当然仍然只是个命令行窗口而以。 运行命令use test，将进入test数据库
mysql>use test; mysql> show tables
    -> ;
Empty set (0.00 sec) 建立一个地址簿数据库：
mysql> create database address; mysql> use address;
Database changed 创建表：
mysql> create　table friends (name Char(15),telphone VarChar(20),qqChar(10), address VarChar(30));
ERROR 1064 (42000): You have an error in your SQL syntax; check themanual that corresponds to your MySQL server version for the rightsyntax to use near 'create　table friends (name Char(15),telphoneVarChar(20),qq Char(10), address ' at line 1
mysql> create table friends (name Char(15),telphone VarChar(20),qqChar(10), address VarChar(30));
Query OK, 0 rows affected (0.01 sec)
新增几笔资料，并查询看看：
mysql> insert into friends values("xyf","123456","359830463","浙江");
Query OK, 1 row affected (0.00 sec) mysql> insert into friends values
    -> (
    -> "myblue",
    -> "6743133"
    -> ,"464313113",
    -> "zhejiang");
Query OK, 1 row affected (0.00 sec) mysql> select * from friends;
+--------+----------+-----------+----------+

| xyf    | 123456   | 359830463 | 浙江   |
| myblue | 6743133  | 464313113 | zhejiang |

　#在控制台上输入
linux:/usr/local/mysql # bin/mysql -u root -p Enter password:
