在CentOS6上搭建LNMP环境（上）

搭建环境：

操作系统：CentOS 6.7

nginx软件：nginx-1.8.1.tar.gz

mysql软件：mysql-5.5.51-linux2.6-x86_64.tar.gz

PHP软件：php-5.6.11.tar.gz

一、LNMP安装前环境准备

1、设置linux防火墙

1）在iptables上开放80,3306,443端口

[[email protected] ~]# vim /etc/sysconfig/iptables

# Firewall configuration written by system-config-firewall

# Manual customization of this file is not recommended.

*filter

:INPUT ACCEPT [0:0]

:FORWARD ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]

-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

-A INPUT -p icmp -j ACCEPT

-A INPUT -i lo -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited

-A FORWARD -j REJECT --reject-with icmp-host-prohibited

COMMIT

[[email protected] ~]# service iptables restart-----重启iptables服务

2）关闭selinux防火墙

[[email protected] ~]# vim /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#     enforcing - SELinux security policy is enforced.

#     permissive - SELinux prints warnings instead of enforcing.

#     disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processes are protected,

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

[[email protected] ~]#setenforc 0

3)安装依赖包

[[email protected] ~]#yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel openldap-clients openldap-servers make  libtool* git tree bison pcre-devel perl gd gd-devel

4）编译安装其他软件

A：安装libiconv软件（该软件支持编码转换为函数）

[[email protected] software]# tar xf libiconv-1.14.tar.gz

[[email protected] libiconv-1.14]# ./configure --prefix=/usr/local

[[email protected] libiconv-1.14]# make && make install

[[email protected] libiconv-1.14]# echo $?

0

（显示0，表示软件编译安装成功了）

B：安装libmcrypt  （加密算法扩展库，支持DES, 3DES, RIJNDAEL, Twofish, IDEA, GOST, CAST-256, ARCFOUR, SERPENT, SAFER+等算法)

[[email protected] software]# tar xf libmcrypt-2.5.7.tar.gz

[[email protected] software]# cd libmcrypt-2.5.7

[[email protected] libmcrypt-2.5.7]# ./configure

[[email protected] libmcrypt-2.5.7]# cd libltdl/

[[email protected] libltdl]# ./configure --enable-ltdl-install

[[email protected] libltdl]# make && make install

C: 安装mhash（mhash的可以用于创建校验数值，消息摘要，消息认证码，以及无需原文的关键信息保存）

[[email protected] software]# tar xf mhash-0.9.9.9.tar.gz

[[email protected] software]# cd mhash-0.9.9.9

[[email protected] mhash-0.9.9.9]# ./configure && make && make install

D：安装mcript（mcrypt 是 php 里面重要的加密支持扩展库，Mcrypt扩展库可以实现加密解密功能，就是既能将明文加密，也可以密文还原。）

[[email protected] software]# tar xf mcrypt-2.6.8.tar.gz

[[email protected] software]# cd mcrypt-2.6.8

[[email protected] mcrypt-2.6.8]# export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

[[email protected] mcrypt-2.6.8]# ./configure && make && make install

E：增加库文件

[[email protected] software]# ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la 

[[email protected] software]# ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so 

[[email protected] software]# ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4 

[[email protected] software]# ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8 

[[email protected] software]# ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a 

[[email protected] software]# ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la 

[[email protected] software]# ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so 

[[email protected] software]# ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2 

[[email protected] software]# ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1 

[[email protected] software]# ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

F：安装cmake （MySQL从5.5版本开始，通过./configure进行编译配置方式已经被取消，取而代之的是cmake工具）

[[email protected] ~]# yum -y install cmake

二、安装mysql数据软件

1）创建mysql用户

[[email protected] software]#groupadd -r mysql

[[email protected] software]# useradd -r -g mysql mysql -s /sbin/nologin

2）创建mysql的数据目录

[[email protected] software]# mkdir -p /data/mysqldb

3）安装mysql

[[email protected] ~]# cd /software/

[[email protected] software]# tar xf mysql-5.5.51-linux2.6-x86_64.tar.gz -C /usr/local/

[[email protected] software]# cd /usr/local/

[[email protected] local]# ll

[[email protected] local]# ln -sv mysql-5.5.51-linux2.6-x86_64/ mysql

`mysql‘ -> `mysql-5.5.51-linux2.6-x86_64/‘

修改mysql目录权限

[[email protected] mysql]# chown -R mysql:mysql .

[[email protected] mysql]# cd /data/mysqldb/

[[email protected] mysqldb]# chown -R mysql:mysql .

初始化mysql数据库

[[email protected] ~]# cd /usr/local/mysql

[[email protected] mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysqldb

编辑mysql配置文件/etc/my.cnf

[mysqld]

datadir=/data/mysqldb

socket=/tmp/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

复制MySQL启动文件及其命令加入PATH

[[email protected] mysql]# cp support-files/mysql.server  /etc/init.d/mysqld

[[email protected] mysql]# chmod +x /etc/init.d/mysqld

[[email protected] mysql]# chkconfig mysqld on

[[email protected] mysql]# vim /etc/profile.d/mysqld.sh

 PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH

[[email protected] mysql]# source /etc/profile.d/mysql.sh

启动mysql服务器

[[email protected] etc]# service mysqld start

Starting MySQL..                                           [  OK  ]

修改root用户的密码及授权普通用户test可以远程连接到mysql数据库

mysql> grant all on *.* to ‘root‘@‘localhost‘ identified by ‘test123‘;

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql> grant all on *.* to ‘test‘@‘%‘ identified by ‘test1234‘;

Ubuntu上搭建Hadoop环境（单机模式+伪分布模式）【转】

[转自:]http://blog.csdn.net/hitwengqi/article/details/8008203 最近一直在自学Hadoop,今天花点时间搭建一个开发环境,并整理成文. 首先要了解一下Hadoop的运行模式: 单机模式(standalone)       单机模式是Hadoop的默认模式.当首次解压Hadoop的源码包时,Hadoop无法了解硬件安装环境,便保守地选择了最小配置.在这种默认模式下所有3个XML文件均为空.当配置文件为空时,Hadoop会完全运行在本地.因为不
