这篇文章主要介绍了shell脚本自动化如何创建虚拟机，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
自动化shell脚本
ps：此处安装的jdk，maven，tomcat均在/opt目录下，如需其他目录或者其他版本，可根据需要改动shell脚本即可。
ps:所有代码全部手敲，已亲测能够使用，全部分享出来。
一：虚拟机初始化
创建shell脚本，把命令放进.sh脚本里，./xx.sh运行此脚本可以完成虚拟机初始化
#!/bin/bash #1.改变机器名 hostnamectl set-hostname $1 #2.打通ip地址 sed -i 's/dhcp/static/' /etc/sysconfig/network-scripts/ifcfgenp0s3 sed -i 's/ONBOOT=no/ONBOOT=yes/' /etc/sysconfig/network-scripts/ifcfgenp0s3 echo "IPADDR=$2" >> /etc/sysconfig/network-scripts/ifcfgenp0s3 systemctl restart network #3.关闭防火墙 systemctl stop firewalld systemctl disable firewalld
二：jdk自动化安装
创建shell脚本，把命令放进.sh脚本里，./xx.sh运行此脚本可以完成jdk自动化安装
#!/bin/bash
jdkTar="/opt/jdk-8u111-linux-x64.tar.gz"
# 检查原先是否已安装
checkExist(){
jdkline1=$(grep -n "export JAVA_HOME=.*" /etc/profile | cut -f1 -d':')
if [ -n "$jdkline1" ];then
echo "存在JAVA_HOME路径，将其删除"
sed -i "${jdkline1}d" /etc/profile
fi
jdkline2=$(grep -n "export CLASSPATH=.*\$JAVA_HOME.*" /etc/profile | cut -f1 -d':')
if [ -n "$jdkline2" ];then
echo "存在CLASSPATH路径，将其删除"
sed -i "${jdkline2}d" /etc/profile
fi
jdkline3=$(grep -n "export PATH=.*\$JAVA_HOME.*" /etc/profile | cut -f1 -d':')
if [ -n "$jdkline3" ];then
echo "存在PATH-JAVA路径，将其删除"
sed -i "${jdkline3}d" /etc/profile
fi
}
# 查询是否有jdk压缩包
if [ -e $jdkTar ];then
echo "--------存在jdk安装包-------"
echo "正在解压jdk安装包。。。"
tar -zxvf /opt/jdk-8u111-linux-x64.tar.gz
if [ -e "/opt/soft2" ];then
echo "存在该文件夹，删除。。"
rm -rf /opt/soft2
fi
echo "---------------------------------"
echo "---------------------------------"
echo "正在建立jdk安装路径。。"
echo "---------------------------------"
echo "---------------------------------"
mkdir -p /opt/soft2/jdk180
mv -f jdk1.8.0_111 /opt/soft2/jdk180
# 检查配置信息
checkExist
echo "---------------------------------"
echo "---------------------------------"
echo "正在配置jdk环境。。。"
sed -i '$a export JAVA_HOME=/opt/soft2/jdk180/jdk1.8.0_111' /etc/profile
sed -i '$a export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar' /etc/profile
sed -i '$a export PATH=$PATH:$JAVA_HOME/bin' /etc/profile
echo "---------------------------------"
echo "---------------------------------"
echo "配置环境已完成。。。"
echo 'this is the end'
echo "---------------------------------"
echo "---------------------------------"
echo "配置版本信息如下："
source /etc/profile
java -version
else
echo "未检测到安装包，请将安装包放到opt目录下"
fi三：maven自动化安装
创建shell脚本，把命令放进.sh脚本里，./xx.sh运行此脚本可以完成maven自动化安装
#!/bin/bash
mavenTar="/opt/apache-maven-3.6.1-bin.tar.gz"
mavenMirror=" <mirror>
<id>alimaven</id>
<mirrorOf>central</mirrorOf>
<name>aliyun maven</name>
<url>https://maven.aliyun.com/repository/central</url>
</mirror>
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
"
mavenrespo="<localRepository>/opt/soft2/maven361/apache-maven-3.6.1/jarstore</localRepository>"
# 检查原先是否已安装
checkExist(){
mavenline1=$(grep -n "export MAVEN_HOME=.*" /etc/profile | cut -f1 -d':')
if [ -n "$mavenline1" ];then
echo "存在MAVEN_HOME路径，将其删除"
sed -i "${mavenline1}d" /etc/profile
fi
mavenline3=$(grep -n "export PATH=.*\$MAVEN_HOME.*" /etc/profile | cut -f1 -d':')
if [ -n "$mavenline3" ];then
echo "存在PATH-MAVEN路径，将其删除"
sed -i "${mavenline3}d" /etc/profile
fi
}
# 查询是否有maven压缩包
if [ -e $mavenTar ];then
echo "--------存在maven安装包-------"
echo "正在解压maven安装包。。。"
tar -zxvf /opt/apache-maven-3.6.1-bin.tar.gz
if [ -e "/opt/soft2/maven361" ];then
echo "存在该文件夹，删除。。"
rm -rf /opt/soft2/maven361
