shell腳本自動化創建虛擬機的基本配置--tomcat--mysql--jdk--maven---媽媽再也不用擔心我不會配置虛擬機了！

自動化shell腳本

ps：此處安裝的jdk，maven，tomcat均在/opt目錄下，如需其他目錄或者其他版本，可根據需要改動shell腳本即可。
ps:所有代碼全部手敲，已親測能夠使用，全部分享出來。
ps：上述代碼在放進sh文件中，需要chmod改變文件權限賦予它執行權限。

chmod 777 xxx.sh

所有文中用到的tar包，均在鏈接中，可自行下載

一：虛擬機初始化

創建shell腳本，把命令放進.sh腳本里，./xx.sh運行此腳本可以完成虛擬機初始化

#!/bin/bash

#1.改變機器名
hostnamectl set-hostname $1

#2.打通ip地址
sed -i 's/dhcp/static/' /etc/sysconfig/network-scripts/ifcfg-enp0s3
sed -i 's/ONBOOT=no/ONBOOT=yes/' /etc/sysconfig/network-scripts/ifcfg-enp0s3
echo "IPADDR=$2" >> /etc/sysconfig/network-scripts/ifcfg-enp0s3
systemctl restart network

#3.關閉防火牆
systemctl stop firewalld
systemctl disable firewalld

二：jdk自動化安裝

創建shell腳本，把命令放進.sh腳本里，./xx.sh運行此腳本可以完成jdk自動化安裝

#!/bin/bash

jdkTar="/opt/jdk-8u111-linux-x64.tar.gz"


# 檢查原先是否已安裝
checkExist(){
	jdkline1=$(grep -n "export JAVA_HOME=.*" /etc/profile | cut -f1 -d':')
        if [ -n "$jdkline1" ];then
                echo "存在JAVA_HOME路徑，將其刪除"
                sed -i "${jdkline1}d" /etc/profile
        fi
	jdkline2=$(grep -n "export CLASSPATH=.*\$JAVA_HOME.*" /etc/profile | cut -f1 -d':')
        if [ -n "$jdkline2" ];then
                echo "存在CLASSPATH路徑，將其刪除"
                sed -i "${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路徑，將其刪除"
                sed -i "${jdkline3}d" /etc/profile
        fi
}


# 查詢是否有jdk壓縮包
if [ -e $jdkTar ];then

	echo "--------存在jdk安裝包-------"
	echo "正在解壓jdk安裝包。。。"
	tar -zxvf /opt/jdk-8u111-linux-x64.tar.gz
	if [ -e "/opt/soft2" ];then
		echo "存在該文件夾，刪除。。"
		rm -rf /opt/soft2
	fi
	echo "---------------------------------"
	echo "---------------------------------"
	echo "正在建立jdk安裝路徑。。"
	echo "---------------------------------"
	echo "---------------------------------"
	mkdir -p /opt/soft2/jdk180
	mv -f jdk1.8.0_111  /opt/soft2/jdk180
	# 檢查配置信息
	checkExist	
	echo "---------------------------------"
	echo "---------------------------------"
	echo "正在配置jdk環境。。。"
	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 "配置環境已完成。。。"
	echo 'this is the end'
	echo "---------------------------------"
    echo "---------------------------------"
    echo "配置版本信息如下："
    source /etc/profile
    java -version
else
	echo "未檢測到安裝包，請將安裝包放到opt目錄下"
fi

三：maven自動化安裝

創建shell腳本，把命令放進.sh腳本里，./xx.sh運行此腳本可以完成maven自動化安裝

#!/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>"

# 檢查原先是否已安裝
checkExist(){
	mavenline1=$(grep -n "export MAVEN_HOME=.*" /etc/profile | cut -f1 -d':')
        if [ -n "$mavenline1" ];then
                echo "存在MAVEN_HOME路徑，將其刪除"
                sed -i "${mavenline1}d" /etc/profile
        fi
	mavenline3=$(grep -n "export PATH=.*\$MAVEN_HOME.*" /etc/profile | cut -f1 -d':')
        if [ -n "$mavenline3" ];then
                echo "存在PATH-MAVEN路徑，將其刪除"
                sed -i "${mavenline3}d" /etc/profile
        fi
}


# 查詢是否有maven壓縮包
if [ -e $mavenTar ];then

	echo "--------存在maven安裝包-------"
	echo "正在解壓maven安裝包。。。"
	tar -zxvf /opt/apache-maven-3.6.1-bin.tar.gz
	if [ -e "/opt/soft2/maven361" ];then
		echo "存在該文件夾，刪除。。"
		rm -rf /opt/soft2/maven361
	fi
	echo "---------------------------------"
	echo "---------------------------------"
	echo "正在建立maven安裝路徑。。"
	echo "---------------------------------"
	echo "---------------------------------"
	mkdir -p /opt/soft2/maven361
	mv -f  apache-maven-3.6.1 /opt/soft2/maven361
	# 檢查配置信息
	checkExist	
	echo "---------------------------------"
	echo "---------------------------------"
	echo "正在配置maven環境。。。"
	sed -i '$a export MAVEN_HOME=/opt/soft2/maven361/apache-maven-3.6.1' /etc/profile
	sed -i '$a export PATH=$PATH:$MAVEN_HOME/bin' /etc/profile
	echo "---------------------------------"
	echo "---------------------------------"
	echo "----正在配置maven鏡像源和mirror----"
	sed -i '/<\/mirrors>/i ${mavenMirror}' /opt/soft2/maven361/apache-maven-3.6.1/conf/settings.xml
	sed -i '/<\/settings>/i ${mavenrespo}' /opt/soft2/maven361/apache-maven-3.6.1/conf/settings.xml

    echo "---------------------------------"
    echo "配置版本信息如下："
    source /etc/profile
    mvn -version
else
	echo "未檢測到安裝包，請將安裝包放到opt目錄下"

fi

四：tomcat自動化安裝

創建shell腳本，把命令放進.sh腳本里，./xx.sh運行此腳本可以完成tomcat自動化安裝

#!/bin/bash

tomcatTar="/opt/apache-tomcat-8.5.54.tar.gz"
    


# 查詢是否有tomcat壓縮包
if [ -e $tomcatTar ];then

	echo "--------存在tomcat安裝包-------"
	echo "正在解壓maven安裝包。。。"
	tar -zxvf /opt/apache-tomcat-8.5.54.tar.gz
	if [ -e "/opt/soft2/tomcat85" ];then
		echo "存在該文件夾，刪除。。"
		rm -rf /opt/soft2/tomcat85
	fi
	echo "---------------------------------"
	echo "---------------------------------"
	echo "正在建立tomcat安裝路徑。。"
	echo "---------------------------------"
	echo "---------------------------------"
	mkdir -p /opt/soft2/tomcat85
	mv -f  apache-tomcat-8.5.54 /opt/soft2/tomcat85
	echo "---------------------------------"
	echo "---------------------------------"
	echo "配置tomcat環境已完成。。。"
	echo 'this is the end'
	echo "---------------------------------"
	echo "---------------------------------"

else
	echo "未檢測到安裝包，請將安裝包放到opt目錄下"
fi

五：mysql自動化安裝

創建shell腳本，把命令放進.sh腳本里，./xx.sh運行此腳本可以完成mysql自動化安裝—mysql腳本要執行兩遍，第一遍可能檢測不到mysql，server無法執行，安裝好後登錄mysql，沒有密碼，直接enter。

#!/bin/bash

mysqlInstall=$(rpm -qa | grep mysql)

mysqlRepoInstall1=$(find /etc/yum.repos.d/ -name "mysql-community.repo" | sed 's#.*/##')

mysqlRepoInstall2=$(find /etc/yum.repos.d/ -name "mysql-community-source.repo" | sed 's#.*/##')

wgetInstall=$(rpm -qa | grep wget)

mariadbInstall=$(rpm -qa | grep mariadb)

# 檢查是否已安裝了mysql，未安裝再安裝
if [ ! -n "${mysqlInstall}" ];then
        # 檢查centOS是否自帶了mariadb，若有則刪除
        if [ -n "${mariadbInstall}" ];then
		echo "自帶mariadb---刪除mariadb中----"
                rpm -e --nodeps mariadb-libs-5.5.64-1.el7.x86_64
		echo "--------------------------------"
		echo "--------------------------------"
		echo "--------------------------------"
	else
		echo "centOS裏沒有mariadb軟件"
		echo "-----------------------"
		echo "-----------------------"
        fi
	if [ -n "${wgetInstall}" ];then
		echo "-------存在wget下載工具-------"
		echo "------------------------------"
		echo "------------------------------"
	else		
		echo "-------安裝下載工具wget-------"
		echo "------------------------------"
		echo "------------------------------"
		yum install -y wget
	fi
		echo "-------在線下載5.7mysql並安裝-------"
		wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
		echo "-----------下載mysql成功-------------"
		echo "-------------------------------------"
		echo "-----------正在安裝mysql中----------"
		echo "-------------------------------------"
		rpm -ivh mysql-community-release-el7-5.noarch.rpm
		echo "-----正在檢測mysql安裝環境是否成功----"
else
	echo "-------------已安裝過mysql--------------"
fi
installmysqlServer(){
	if [ "${mysqlRepoInstall1}" = "mysql-community.repo" -a "${mysqlRepoInstall2}" = "mysql-community-source.repo" ];then
                        echo "存在2個mysql安裝環境，下載安裝完成。。。"
                        echo "----------------------------------------"
                        echo "----------------------------------------"
			echo "-----------安裝mysql-server中-----------"
                        echo "----------------------------------------"
                        echo "----------------------------------------"
			if [ ! -e "/var/lib/mysql" ];then
				yum install -y mysql-server
			else
				echo "-----已安裝過mysql-server-----"
			fi
                        echo "修改訪問權限爲當前用戶。。。"
                        chown -R root:root /var/lib/mysql
                        ls -l /var/lib
                        echo "重啓mysql服務中"
                        service mysqld restart
                        echo "安裝完成---請登錄mysql修改密碼和字符集"
        else
                        echo "${mysqlRepoInstall1}"
                        echo "${mysqlRepoInstall2}"
                        echo "----沒有安裝成功----"
	fi
}
