下载apache-tomcat-8.0.50.tar.gz | jdk1.8.0_131.tar.gz | tomcat-native-1.2.31-src.tar.gz三个文件

搭建过程

上传文件至服务器

解压文件

[root@fcz ~]# tar zxf apache-tomcat-8.0.50.tar.gz 
[root@fcz ~]# tar zxf jdk1.8.0_131.tar.gz 
[root@fcz ~]# tar zxf tomcat-native-1.2.31-src.tar.gz 

把jdk和tomcat、native移动到/usr/local下，避免权限不足的问题

[root@fcz ~]# mv apache-tomcat-8.0.50 tomcat
[root@fcz ~]# mv tomcat /usr/local/
[root@fcz ~]# mv jdk1.8.0_131 /usr/local/
[root@fcz ~]# mv tomcat-native-1.2.31-src  /usr/local/

配置Java环境变量

进入 /etc/profile 文件

[root@fcz etc]# vim /etc/profile

在文件末尾添加环境变量

export JAVA_HOME=/usr/local/jdk1.8.0_131
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin

[root@fcz etc]# source  /etc/profile    //使环境变量立刻生效

测试环境变量是否配置成功

查看Java版本

[root@fcz etc]# java    -version 

如显示和上传的的Java版本一致则环境变量配置成功

启动tomcat

腾讯云安全组防火墙放行8080端口

我这是轻量级服务器可能和标准服务器有点不一样，不过问题不大

启动tomcat

进入tomcat/bin文件夹

[root@fcz ~]# cd /usr/local/tomcat/bin

执行启动脚本

[root@fcz bin]# ./startup.sh 

访问tomcat网址

更改tomcat为apr运行模式

安装apr

[root@fcz ~]# yum -y install apr apr-devel   ---apr扩展

安装native

[root@fcz local]# cd /usr/local/
[root@fcz local]# cd tomcat-native-1.2.31-src/native/
[root@fcz local]# ./configure --with-apr=/usr/bin/apr-1-config
[root@fcz local]# make && make install

设置apr环境变量

在/etc/profile中加入

export CATALINA_OPTS=-Djava.library.path=/usr/local/apr/lib

source /etc/profile  ----使环境变量生效

修改tomcat配置文件

[root@fcz native]# vim /usr/local/tomcat/conf/server.xml

修改以下内容：
<Connector port="8080" protocol="HTTP/1.1"
                connectionTimeout="20000"
                redirectPort="8443" />
修改protocol的值为org.apache.coyote.http11.Http11AprProtocol

<Connector port="8080" protocol="org.apache.coyote.http11.Http11AprProtocol"
                connectionTimeout="20000"
                redirectPort="8443" />

修改修改后进入/usr/local/tomcat/bin目录重启tomcat
 ./shutdown.sh    ---关闭Tomcat
 ./startup.sh     ---开启Tomcat

重启后进入/usr/local/tomcat/logs查看日志文件
vim  catalina.out
点击大写G跳转至文件末尾

或者 
tail -f   /usr/local/tomcat/logs/catalina.out

如有以下文字表示更改完成，重要的是最后两行http和ajp的模式
