Linux环境说明 linux操作系统:CentOS 1. 下载CentOS系统对应的MySQL版本 下载地址:http://dev.mysql.com/downloads/mysql/ Select platform:Linux-generic; 版本:根据你计算机的位数选择相应的版本。(32位,或者64位系统) 2. 下载后有以下几个rpm文件:
Linux环境说明
linux操作系统:CentOS
1. 下载CentOS系统对应的MySQL版本
下载地址:http://dev.mysql.com/downloads/mysql/
Select platform:Linux-generic;
版本:根据你计算机的位数选择相应的版本。(32位,或者64位系统)
2. 下载后有以下几个rpm文件:
3、如果你只是需要安装mysql,那么只需要安装如下文件
MySQL-server-5.6.22-1.linux_glibc2.5.x86_64.rpm
MySQL-client-5.6.22-1.linux_glibc2.5.x86_64.rpm
MySQL-devel-5.6.22-1.linux_glibc2.5.x86_64.rpm
MySQL-server-5.5.25a-1.rhel5.x86_64.rpm、MySQL-client-5.5.25a-1.rhel5.x86_64.rpm和MySQL-devel-5.5.25a-1.rhel5.x86_64.rpm三个文件换成MySQL-server-5.6.22-1.linux_glibc2.5.x86_64.rpm、MySQL-client-5.6.22-1.linux_glibc2.5.x86_64.rpm和MySQL-devel-5.6.22-1.linux_glibc2.5.x86_64.rpm三个rpm文件即可)
查看当前安装的linux版本
命令:lsb_release -a 如下图所示
通过上图中的数据可以看出安装的版本为CentOS release 6.3,所以我们需要下载CentOS release 6.3对应的mysql安装包
下载mysql安装文件
1、如果你只是需要安装mysql,那么只需要安装如下文件
MySQL-server-5.5.25-1.rhel5
MySQL-devel-5.5.25-1.rhel5
MySQL-client-5.5.25-1.rhel5
2、如果你需要搭建Linux整个实施环境(nginx、php、mysql、tomcat、jdk、服务器多域名配置)
请参考我的Linux项目实施系列教程:
CenterOS 6.3 64位搭建nginx1.3+php5.4.3+mysql5.5.25+tomcat7+jdk7安装
安装mysql5.5.25
1、进入安装文件的目录
2、安装mysql服务端
# rpm -ivh MySQL-server-5.5.25a-1.rhel5.x86_64.rpm
如图:mysql-server安装
安装过程中可能出现后面的错误:error:
Failed dependencies: libaio.so.1()(64bit) is needed by MySQL-server
(蓝色部分可以跳过)
(1) 安装完成后,安装进程会在Linux中添加一个mysql组,以及属于mysql组的用户mysql。可通过id命令查看:
[root@localhost JavaEE]#id mysql
uid=496(mysql)gid=493(mysql) groups=493(mysql)
(2)MySQL服务器安装之后虽然配置了相关文件,但并没有自动启动mysqld服务,需自行启动:[root@localhost JavaEE]#service mysql start
Starting MySQL.. SUCCESS!
(3) 可通过检查端口是否开启来查看MySQL是否正常启动:
[root@localhost JavaEE]#netstat -anp|grep 3306
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 34693/mysqld
3、安装mysql客户端、mysql-devel
# rpm -ivh MySQL-client-5.5.25a-1.rhel5.x86_64.rpm
# rpm -ivh MySQL-devel-5.5.25a-1.rhel5.x86_64.rpm
如图:mysql-client-devel
启动mysql服务
# service mysql start
3.初始密码问题
安装好mysql之后,一般有两种情况:
第一种情况:为root用户设置了一个随机密码(在CentOS上经常遇到这种情况)
随机密码存放位置:/root/.mysql_secret(这个是隐藏文件,想看密码直接输入:vi /root/.mysql_secret)
文件中的内容如下:
# The random password set for the root user at Fri Feb 6 11:18:43 2015 (local time): eSADSovuu3jDdxs9
#
第一步:取到随机密码登录;
第二步:登录成功后修改密码命令如下:
sql>set passwrod = password("newpassword");
第二种情况:一开始root未设置密码
修改mysql中root的初始化密码
1、命令如下:
# /usr/bin/mysqladmin -u root password ‘rootadmin’
格式:mysqladmin -u用户名 -p旧密码 password 新密码
2、例子
# /usr/bin/mysqladmin -u root password ‘rootadmin’
注:因为开始时root没有密码,所以-p旧密码一项就可以省略了

重启与停止mysql服务
启动方式1:service mysql start
启动方式2:/etc/init.d/mysql start
停止方式1:service mysql stop
停止方式2:/etc/init.d/mysql shutdown
重启方式1:service mysql restart
重启方式2:/etc/init.d/mysql restart

The key differences between CentOS and Ubuntu are: origin (CentOS originates from Red Hat, for enterprises; Ubuntu originates from Debian, for individuals), package management (CentOS uses yum, focusing on stability; Ubuntu uses apt, for high update frequency), support cycle (CentOS provides 10 years of support, Ubuntu provides 5 years of LTS support), community support (CentOS focuses on stability, Ubuntu provides a wide range of tutorials and documents), uses (CentOS is biased towards servers, Ubuntu is suitable for servers and desktops), other differences include installation simplicity (CentOS is thin)

Common problems and solutions for Hadoop Distributed File System (HDFS) configuration under CentOS When building a HadoopHDFS cluster on CentOS, some common misconfigurations may lead to performance degradation, data loss and even the cluster cannot start. This article summarizes these common problems and their solutions to help you avoid these pitfalls and ensure the stability and efficient operation of your HDFS cluster. Rack-aware configuration error: Problem: Rack-aware information is not configured correctly, resulting in uneven distribution of data block replicas and increasing network load. Solution: Double check the rack-aware configuration in the hdfs-site.xml file and use hdfsdfsadmin-printTopo

Building a Hadoop Distributed File System (HDFS) on a CentOS system requires multiple steps. This article provides a brief configuration guide. 1. Prepare to install JDK in the early stage: Install JavaDevelopmentKit (JDK) on all nodes, and the version must be compatible with Hadoop. The installation package can be downloaded from the Oracle official website. Environment variable configuration: Edit /etc/profile file, set Java and Hadoop environment variables, so that the system can find the installation path of JDK and Hadoop. 2. Security configuration: SSH password-free login to generate SSH key: Use the ssh-keygen command on each node
