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/ifcfgenp0s3sed -i 's/ONBOOT=no/ONBOOT=yes/' /etc/sysconfig/network-scripts/ifcfgenp0s3echo "IPADDR=$2" >> /etc/sysconfig/network-scripts/ifcfgenp0s3systemctl restart network#3.关闭防火墙systemctl stop firewalldsystemctl disable firewalld二：jdk自动化安装
创建shell脚本，把命令放进.sh脚本里，./xx.sh运行此脚本可以完成jdk自动化安装
#!/bin/bashjdkTar="/opt/jdk-8u111-linux-x64.tar.gz"# 检查原先是否已安装checkExist(){jdkline1=$(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 fijdkline2=$(grep -n "export CLASSPATH=.*\$JAVA_HOME.*" /etc/profile | cut -f1 -d':') if [ -n "$jdkline2" ];then echo "存在CLASSPATH路径，将其删除" sed -i "${jdkline2}d" /etc/profile fijdkline3=$(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 $jdkTar ];thenecho "--------存在jdk安装包-------"echo "正在解压jdk安装包。。。"tar -zxvf /opt/jdk-8u111-linux-x64.tar.gzif [ -e "/opt/soft2" ];thenecho "存在该文件夹，删除。。"rm -rf /opt/soft2fiecho "---------------------------------"echo "---------------------------------"echo "正在建立jdk安装路径。。"echo "---------------------------------"echo "---------------------------------"mkdir -p /opt/soft2/jdk180mv -f jdk1.8.0_111 /opt/soft2/jdk180# 检查配置信息checkExistecho "---------------------------------"echo "---------------------------------"echo "正在配置jdk环境。。。"sed -i '$a export JAVA_HOME=/opt/soft2/jdk180/jdk1.8.0_111' /etc/profilesed -i '$a export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar' /etc/profilesed -i '$a export PATH=$PATH:$JAVA_HOME/bin' /etc/profileecho "---------------------------------"echo "---------------------------------"echo "配置环境已完成。。。"echo 'this is the end'echo "---------------------------------" echo "---------------------------------" echo "配置版本信息如下：" source /etc/profile java -versionelseecho "未检测到安装包，请将安装包放到opt目录下"fi三：maven自动化安装
创建shell脚本，把命令放进.sh脚本里，./xx.sh运行此脚本可以完成maven自动化安装
#!/bin/bashmavenTar="/opt/apache-maven-3.6.1-bin.tar.gz"mavenMirror=" <mirror> <id>alimaven</id> <mirrorOf>central</mirrorOf> <name>aliyun maven</name> <url>https://maven.aliyun.com/repository/central</url> </mirror> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror>"mavenrespo="<localRepository>/opt/soft2/maven361/apache-maven-3.6.1/jarstore</localRepository>"# 检查原先是否已安装checkExist(){mavenline1=$(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 fimavenline3=$(grep -n "export PATH=.*\$MAVEN_HOME.*" /etc/profile | cut -f1 -d':') if [ -n "$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 $mavenTar ];thenecho "--------存在maven安装包-------"echo "正在解压maven安装包。。。"tar -zxvf /opt/apache-maven-3.6.1-bin.tar.gzif [ -e "/opt/soft2/maven361" ];thenecho "存在该文件夹，删除。。"rm -rf /opt/soft2/maven361fiecho "---------------------------------"echo "---------------------------------"echo "正在建立maven安装路径。。"echo "---------------------------------"echo "---------------------------------"mkdir -p /opt/soft2/maven361mv -f apache-maven-3.6.1 /opt/soft2/maven361# 检查配置信息checkExistecho "---------------------------------"echo "---------------------------------"echo "正在配置maven环境。。。"sed -i '$a export MAVEN_HOME=/opt/soft2/maven361/apache-maven-3.6.1' /etc/profilesed -i '$a export PATH=$PATH:$MAVEN_HOME/bin' /etc/profileecho "---------------------------------"echo "---------------------------------"echo "----正在配置maven镜像源和mirror----"sed -i '/<\/mirror>/i ${mavenMirror}' /opt/soft2/maven361/apache-maven-3.6.1/conf/settings.xmlsed -i '/<\/settings>/i ${mavenrespo}' /opt/soft2/maven361/apache-maven-3.6.1/conf/settings.xmlecho "---------------------------------"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 mvn -versionelseecho "未检测到安装包，请将安装包放到opt目录下"fi四：tomcat自动化安装
