摘要：
如果安装了Tomcat，查看版本的方法如下：注意：首先转到Tomcat的bin目录（cd/Tomcat directory/bin），然后执行./version。什[root@izbpbin]#./版本。shUsingCATALINA_BASE：/usr/local/tomcat使用CATALINA_HOME:/usr/local/tom cat使用CATELINA_TMPDIR:/usr/loc
如果安装了Tomcat查看版本方法如下：
注意：先进到tomcat的bin目录下（cd /tomcat目录/bin），在执行./version.sh
[root@izbp 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/java/jdk1.8.0_141 Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar Server version: Apache Tomcat/8.5.23 Server built: Sep 28 2017 10:30:11 UTC Server number: 8.5.23.0 OS Name: Linux OS Version: 3.10.0-514.26.2.el7.x86_64 Architecture: amd64 JVM Version: 1.8.0_141-b15 JVM Vendor: Oracle Corporation
下载tomcat8到你的某个目录下:
[root@iZbp11 etc]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.39/bin/apache-tomcat-8.5.39.tar.gz --2019-03-27 10:00:59-- http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.39/bin/apache-tomcat-8.5.39.tar.gz Resolving mirrors.tuna.tsinghua.edu.cn (mirrors.tuna.tsinghua.edu.cn)... 101.6.8.193, 2402:f000:1:408:8100::1 Connecting to mirrors.tuna.tsinghua.edu.cn (mirrors.tuna.tsinghua.edu.cn)|101.6.8.193|:80... connected.

如上面的示例，我们下载了apache-tomcat-8.5.39版本的tomcat即下图示文件：
解压此文件：
tar -zxvf apache-tomcat-8.5.39.tar.gz
即可，下面是配置
首先配置:nginx(在nginx环境下复制一份tomcat.conf配置文件）
# cd /etc/nginx/conf.d/ # cp default.conf tomcat.conf # nano tomcat.conf
请在tomcat.conf里输入:
server { listen 80; server_name mydomain.com; index index.jsp; root /usr/share/nginx/html/h5; location / { proxy_pass http://mydomain.com:8080; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }
这里请注意:mydomain.com是你的域名,/usr/share/nginx/html/h5是你的项目路径,要与下面的tomcat对应起来.
其次,修改Server.xml
# nano /usr/local/tomcat/conf/server.xml
请修改如下:
<Host name="mydomain.com" appBase="/usr/share/nginx/html/h5" unpackWARs="true" autoDeploy="true"> <Context path="" docBase="/usr/share/nginx/html/h5" debug="0" reloadable="false" crossContext="tr$ <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> </Host>
重启各涉及到的服务然后启动tomcat :
./startup.sh
如果遇到如下错误，可是是环境变量有问题或者没有安装JDK
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined At least one of these environment variable is needed to run this program
安装JDK
安装前先查询一下系统有没有安装jdk及安装目录，用下面的命令：
#whereis java
卸载centos原本自带的openjdk，运行命令：rpm -qa | grep java
下载jkd8
或者访问地址：https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
#wget https://download.oracle.com/otn-pub/java/jdk/8u201-b09/42970487e3af4f5aa5bca3f542482c60/jdk-8u201-linux-x64.tar.gz?AuthParam=1553657831_881ef7dbb106ac2099854005bfbe2adb
配置环境
nano /etc/profile
添加如下代码：
export JAVA_HOME=/etc/java/jdk8 export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib export PATH=$JAVA_HOME/bin:$PATH
生效jdk环境变量：
source /etc/profile
检查JDK是否安装成功：
java -version
