CentOS6.5下安装环境安装文档（安装centos6.5详细步骤）

----------------CentOS6.5下安装JDK1.7+MYSQL5.5+TOMCAT7+nginx1.7.5环境安装文档-----------------------

【JDK1.7安装】

1)登录Sun的JDK官方下载网 址:http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

2)下载jdk-7u67-linux-x64.rpm文件

》删除系统自带OpenJDK

CentOs6.5 默认会安装OpenOffice之类，需要JAVA支持，系统默认安装了一个openjdk1.7版本

# java -version

java version "1.7.0"

OpenJDK Runtime Environment (build 1.7.0-b09)

OpenJDK Client VM (build 1.7.0-b09, mixed mode)

备注：

无须删除原有的openjdk;否则，与之相关的openoffice等软件，也会自动随之删除；

如果直接"应用程序-添加/删除软件--基本系统--java“删除其他相关软件也会自动删除，所以删除前，最好安装配置好新的JDK环境

1) 删除原有的JDK：

# rpm -qa|grep jdk

查看安装的JDK，会显示多个java-1.7.0-openjdk-1.7.0相关的程序，在以下一一卸载。直到删完为止，如下：

# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.65-2.5.1.2.el65.x8664

# rpm -e --nodeps java-1.7.0-openjdk-devel-1.7.0.65-2.5.1.2.el65.x8664

# rpm -e --nodeps java-1.7.0-openjdk-demo-1.7.0.65-2.5.1.2.el65.x8664

......

# rpm -qa|grep java

查看安装的JAVA关联程序，在以下一一卸载。直到删完为止，如下：

# rpm -e --nodeps tzdata-java-2014h-1.el6.noarch

......

》配置新的JDK环境

1）把安装文件文件保存在/usr/java/tools下 ,并切换到root用户

# mkdir /usr/java 创建/urs/java目录

# cd /usr/java/

# rpm -ivh ./tools/jdk-7u67-linux-x64.rpm

》配置jdk1.6.0_22环境变量

# vi /etc/profile

JAVAHOME=/usr/java/jdk1.7.079

JREHOME=/usr/java/jdk1.7.079/jre

PATH=$PATH:$JAVAHOME/bin:$JREHOME/bin

CLASSPATH=:$JAVAHOME/lib/dt.jar:$JAVAHOME/lib/tools.jar:$JRE_HOME/lib

export JAVAHOME JREHOME PATH CLASSPATH

》使环境变量生效：

#source /etc/profile

》测试安装

1)查看版本号

# java -version

java version "1.7.0_67"

Java(TM) SE Runtime Environment (build 1.7.0_67-b01)

Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)

说明成功了。

【MYSQL5.5的安装】

安装方式分为rpm和源码编译安装两种，本文是采用mysql源码编译方式，编译器使用Cmake。软件需要mysql-5.5.40.tar.gz和cmake-2.8.10.2.tar.gz，请自行下载。

》下载地址：

http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.40.tar.gz

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

其中mysql使用最新的稳定版本，即最新试用版的上一个版本，且非rc或者alpha的版本，Cmake直接用的最新版。

》上传mysql-5.5.40.tar.gz和cmake-2.8.10.2.tar.gz到/usr/java/tools文件夹下。

》CentOS安装g++和ncurses-devel

# yum install gcc-c++

# yum install ncurses-devel

》cmake的安装

# mkdir -p /usr/java/make

# cd /usr/java/make

# mv ../tools/cmake-2.8.10.2.tar.gz ./

# tar -zxv -f cmake-2.8.10.2.tar.gz

# cd cmake-2.8.10.2

# ./configure

# make

# make install

》将cmake永久加入系统环境变量

》用vi在文件/etc/profile文件中增加变量，使其永久有效，

# vi /etc/profile

》在文件PATH中加入MAKE_PATH环境变量：

JAVAHOME=/usr/java/jdk1.7.067

JREHOME=/usr/java/jdk1.7.067/jre

MAKE_PATH=/usr/java/cmake/cmake-2.8.10.2/bin

PATH=$MAKEPATH:$PATH:$JAVAHOME/bin:$JRE_HOME/bin

CLASSPATH=:$JAVAHOME/lib/dt.jar:$JAVAHOME/lib/tools.jar:$JRE_HOME/lib

export JAVAHOME JREHOME PATH CLASSPATH

》执行以下代码使刚才的修改生效：

# source /etc/profile

》用 export 命令查看PATH值

# echo $PATH

》创建mysql的安装目录及数据库存放目录

# mkdir -p /usr/java/mysql //安装mysql

# mkdir -p /usr/java/mysql/data //存放数据库

》创建mysql用户及用户组

# groupadd mysql

# useradd -r -g mysql mysql

》编译安装mysql

# cd /usr/java/mysql

# tar zxvf ../tools/mysql-5.5.40.tar.gz

# cd mysql-5.5.40/

# cmake -DCMAKEINSTALLPREFIX=/usr/java/mysql

-DMYSQLUNIXADDR=/usr/java/mysql/mysql.sock

-DDEFAULT_CHARSET=utf8

-DDEFAULTCOLLATION=utf8general_ci

-DWITHMYISAMSTORAGE_ENGINE=1

-DWITHINNOBASESTORAGE_ENGINE=1

-DWITHMEMORYSTORAGE_ENGINE=1

-DWITH_READLINE=1

-DENABLEDLOCALINFILE=1

-DMYSQL_DATADIR=/usr/java/mysql/data

-DMYSQL_USER=mysql

-DMYSQLTCPPORT=6666

# make

# make install

》检验是否安装成功

# cd /usr/java/mysql

[root@fiona mysql]# ls

bin data include lib mysql-5.5.40 mysql-test scripts sql-bench

COPYING docs INSTALL-BINARY man mysql.sock README share support-files

有bin等以上文件的话，恭喜你已经成功安装了mysql。

》配置mysql

》设置mysql目录权限

# cd /usr/java/mysql //把当前目录中所有文件的所有者设为root，所属组为mysql

# chown -R root:mysql .

# chown -R mysql:mysql data

》将mysql的启动服务添加到系统服务中

# cp support-files/my-medium.cnf /etc/my.cnf

cp：是否覆盖"/etc/my.cnf"？ y

》创建系统数据库的表

# cd /usr/java/mysql

# scripts/mysqlinstalldb --user=mysql

》设置环境变量

# vi /root/.bash_profile

在修改PATH=$PATH:$HOME/bin为：

PATH=$PATH:$HOME/bin:/usr/java/mysql/bin:/usr/java/mysql/lib

# source /root/.bash_profile //使刚才的修改生效

》手动启动mysql

# ./bin/mysqld_safe --user=mysql & //启动MySQL，但不能停止

mysqladmin -u root -p shutdown //此时root还没密码，所以为空值，提示输入密码时，直接回车即可。

》将mysql的启动服务添加到系统服务中

# cp support-files/mysql.server /etc/init.d/mysql

》启动mysql

# service mysql start

Starting MySQL... ERROR! The server quit without updating PID file (/usr/java/mysql/data/localhost.localdomain.pid).

》启动失败：

》我这里是权限问题，先改变权限

# chown -R mysql:mysql /usr/java/mysql

》接着启动服务器

# /etc/init.d/mysql start

》修改MySQL的root用户的密码以及打开远程连接

# mysql -u root mysql

mysql> use mysql;

mysql> desc user;

mysql> GRANT ALL PRIVILEGES ON . TO root@"%" IDENTIFIED BY "root"; //为root添加远程连接的能力

mysql> update user set Password = password('x123456.') where User='root'; //设置root用户密码

mysql> select Host,User,Password from user where User='root';

mysql> flush privileges;

mysql> exit

》重新登录

# mysql -u root -p

enter password:x123456.000

》若还不能进行远程连接，关闭防火墙

[root@localhost]# /etc/rc.d/init.d/iptables stop

用远程工具连接上了表示成功了。

【TOMCAT7.0的安装】

》先下载apache-tomcat-7.0.56.tar.gz

》下载地下：http://mirrors.hust.edu.cn/apache/tomcat/tomcat-7/v7.0.56/bin/apache-tomcat-7.0.56.tar.gz

【nginx-1.7.6.tar.gz的安装】

》先下载nginx-1.7.6.tar.gz

》下载URL:http://nginx.org/download/nginx-1.7.6.tar.gz

》把nginx-1.7.6.tar.gz放到/usr/java/tools目录下

# cd /usr/local/
