linux服务器自动安装jdk，nginx，redis

        由于项目中包含几十台服务器，且服务器都需要自己运维，安装使用环境很浪费时间，而且每10台服务器共用1个nas，这里我写了个shell脚本，将安装包和脚本都放在nas里，然后通过运行脚本直接安装。

        安装jdk命令：sh installSoftware.sh installJava

        安装nginx命令：sh installSoftware.sh installNginx

        安装redis命令：sh installSoftware.sh installRedis

        安装所有环境命令：sh installSoftware.sh installAll

下面贴出shell脚本：

#!/bin/bash
#定义变量
#自动部署java
installJava() {
	mkdir /usr/java
	mkdir /software
	cp -rf /nas/software/jdk-8u121-linux-x64.gz /software/
	cd /software
	tar -zxf jdk-8u121-linux-x64.gz
	mv /software/jdk1.8.0_121 /usr/java/
	echo "export JAVA_HOME=/usr/java/jdk1.8.0_121"  >> /etc/profile
	echo "export JAVA_BIN=/usr/java/jdk1.8.0_121/bin"  >> /etc/profile
	echo "export PATH=$JAVA_HOME/bin:$PATH"  >> /etc/profile
	echo "export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar"  >> /etc/profile
	echo "export JAVA_HOME JAVA_BIN PATH CLASSPATH"  >> /etc/profile
	source /etc/profile
}
#自动部署nginx
installNginx() {
	yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
