Ubuntu 14.04下MySQL服务器和客户端的安装
现在的软件越来越好安装,尤其是在ubuntu下安装软件,更是没有技巧,只需要在联网的情况下使用apt-get inatll 即可。在决定安装mysql之前,要先确定系统是否已经安装mysql。
hadoop@master:~$ netstat -tap | grep mysql (并非所有进程都能被检测到,所有非本用户的进程信息将不会显示,如果想看到所有信息,则必须切换到 root 用户)
由此可以看出系统中并没有安装mysql,执行以下命令进行安装。
hadoop@master:~$ sudo apt-get install mysql-server 正在读取软件包列表... 完成 正在分析软件包的依赖关系树 正在读取状态信息... 完成 将会安装下列额外的软件包: libdbd-mysql-perl libdbi-perl libhtml-template-perl libmysqlclient18 libterm-readkey-perl mysql-client-5.5 mysql-common mysql-server-5.5 mysql-server-core-5.5 建议安装的软件包: libmldbm-perl libnet-daemon-perl libplrpc-perl libsql-statement-perl libipc-sharedcache-perl tinyca mailx 下列【新】软件包将被安装: libdbd-mysql-perl libdbi-perl libhtml-template-perl libmysqlclient18 libterm-readkey-perl mysql-client-5.5 mysql-common mysql-server mysql-server-5.5 mysql-server-core-5.5 升级了 0 个软件包,新安装了 10 个软件包,要卸载 0 个软件包,有 158 个软件包未被升级。 需要下载 8,343 kB 的软件包。 解压缩后会消耗掉 86.8 MB 的额外空间。 您希望继续执行吗? [Y/n]
输入Y进入到安装界面,在安装过程中,会弹出一个界面要求输入mysql的root的密码,这里一定输入,省得安装后再设密码了。
再次输入密码:

mysql安装完成后,我们可以通过netstat -tap|grep mysql来查看系统是否已经有了mysql服务。
出现上面的信息,说明我们安装mysql成功。
执行以下命令可以查看MySQL的版本:
hadoop@master:~$ mysql -V mysql Ver 14.14 Distrib 5.5.38, for debian-linux-gnu (i686) using readline 6.3
下面进行简单的配置
安装完成后通过修改/etc/mysql/my.cnf(此文件为mysql的配置文件)。将文件中的binding-address=127.0.0.1注释掉。其它配置根据需要更改。
hadoop@master:~$ sudo vi /etc/mysql/my.cnf # Instead of skip-networking the default is now to listen only on # localhost which is more compatible and is not less secure. #bind-address = 127.0.0.1
登录数据库:
hadoop@master:~$ msyql -u root -p 未找到 'msyql' 命令,您要输入的是否是: 命令 'mysql' 来自于包 'percona-xtradb-cluster-client-5.5' (universe) 命令 'mysql' 来自于包 'mysql-client-core-5.5' (main) 命令 'mysql' 来自于包 'mariadb-client-core-5.5' (universe) 命令 'mysql' 来自于包 'mysql-client-core-5.6' (universe) msyql:未找到命令
出现改错误原因是没有安装MySQL客户端,执行命令安装MySQL对应的客户端:
hadoop@master:~$ sudo apt-get install mysql-client 正在读取软件包列表... 完成 正在分析软件包的依赖关系树 正在读取状态信息... 完成 下列【新】软件包将被安装: mysql-client 升级了 0 个软件包,新安装了 1 个软件包,要卸载 0 个软件包,有 158 个软件包未被升级。 需要下载 12.3 kB 的软件包。 解压缩后会消耗掉 129 kB 的额外空间。 获取:1 http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main mysql-client all 5.5.38-0ubuntu0.14.04.1 [12.3 kB] 下载 12.3 kB,耗时 1秒 (10.2 kB/s) Selecting previously unselected package mysql-client.

安装完成,再次登录MySQL:
hadoop@master:~$ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 43 Server version: 5.5.38-0ubuntu0.14.04.1 (Ubuntu) Copyright (c) 2000, 2014, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql>
执行以下命令,配置mysql远程访问:
mysql> grant all privileges on *.* to root@'%' identified by "root"; Query OK, 0 rows affected (0.01 sec)
重启msyql服务即可远程访问
hadoop@master:~$ sudo service mysql restart mysql stop/waiting mysql start/running, process 32359
到此安装和配置完成。
