## tomcat 编译安装 ##

### 安装jdk环境 ###

##yum方式安装 
    yum -y install java-1.8.0-openjdk.x86_64
    
    ##编译安装
    官网下载tar包
    tar xf jdk-8u201-linux-x64.tar.gz -C /usr/local/
    cd /usr/local/
    ln -s jdk1.8.0_201/ java
    ## 添加环境变量
    [root@tomcat_web ~]# vim /etc/profile 
    export JAVA_HOME=/usr/local/java
    export JRE_HOME=/usr/local/java/jre
    export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
    ## 加载修改的变量
    source /etc/profile 
    ## 查看是否安装成功
    java -version

### 安装tomcat ###

下载tar包

wget https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-8/v8.5.65/bin/apache-tomcat-8.5.65.tar.gz
    tar -xvf apache-tomcat-8.5.65.tar.gz -C /usr/local/
    cd /usr/local/
    ln -s apache-tomcat-8.5.65/ tomcat
    ## 添加环境变量-替换上面的jdk修改内容
    vim /etc/profile
    
    export JAVA_HOME=/usr/local/java
    export TOMCAT_HOME=/usr/local/tomcat
    export JRE_HOME=/usr/local/java/jre
    export PATH=$TOMCAT_HOME/bin:$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
    
    ## 授权
    chown -R root.root /usr/local/jdk/ /usr/local/tomcat/
    ## 检查是否安装完成
    [root@localhost tomcat]# /usr/local/tomcat/bin/version.sh
    Using CATALINA_BASE:   /usr/local/tomcat
    Using CATALINA_HOME:   /usr/local/tomcat
    Using CATALINA_TMPDIR: /usr/local/tomcat/temp
    Using JRE_HOME:        /usr/local/java/jre
    Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
    Using CATALINA_OPTS:
