----------------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 $PATH
》创建mysql的安装目录及数据库存放目录
# mkdir -p /usr/java/mysql //安装mysql
# mkdir -p /usr/java/mysql/data //存放数据库
》创建mysql用户及用户组
# groupadd mysql
# useradd -r -g mysql mysql
》编译安装mysql
# cd /usr/java/mysql
# tar zxvf ../tools/mysql-5.5.40.tar.gz
# cd mysql-5.5.40/
# cmake -DCMAKEINSTALLPREFIX=/usr/java/mysql
-DMYSQLUNIXADDR=/usr/java/mysql/mysql.sock
-DDEFAULT_CHARSET=utf8
-DDEFAULTCOLLATION=utf8general_ci
-DWITHMYISAMSTORAGE_ENGINE=1
-DWITHINNOBASESTORAGE_ENGINE=1
-DWITHMEMORYSTORAGE_ENGINE=1
-DWITH_READLINE=1
-DENABLEDLOCALINFILE=1
-DMYSQL_DATADIR=/usr/java/mysql/data
-DMYSQL_USER=mysql
-DMYSQLTCPPORT=6666
# make
# make install
》检验是否安装成功
# cd /usr/java/mysql
[[email protected] mysql]# ls
bin data include lib mysql-5.5.40 mysql-test scripts sql-bench
COPYING docs INSTALL-BINARY man mysql.sock README share support-files
有bin等以上文件的话，恭喜你已经成功安装了mysql。
》配置mysql
》设置mysql目录权限
# cd /usr/java/mysql //把当前目录中所有文件的所有者设为root，所属组为mysql
# chown -R root:mysql .
# chown -R mysql:mysql data
》将mysql的启动服务添加到系统服务中
# cp support-files/my-medium.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
》创建系统数据库的表
# cd /usr/java/mysql
# scripts/mysqlinstalldb --user=mysql
》设置环境变量
# vi /root/.bash_profile
在修改PATH=$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
[[email protected]]# /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
