Centos6.8-java-tomcat 环境搭建

步骤

• yum update
• yum install centos-release-scl
• yum install apr-devel openssl-devel gcc make
• 下载Java-1.8

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u141-linux-x64.tar.gz"

tar -zxvf jdk-8u141-linux-x64.tar.gz

mv ./jdk1.8.0_141 /usr/java

• 下载tomcat8.5

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.5.40/bin/apache-tomcat-8.5.40.tar.gz

tar -zxvf apache-tomcat-8.5.40.tar.gz

mv ./apache-tomcat-8.5.40 /usr/local/tomcat

配置jdk

• 配置环境变量

vim /etc/profile

export JAVA_HOME=/usr/java
export JRE_HOME=/usr/java/jre
export CLASS_PATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export TOMCAT_PATH=/usr/local/tomcat
export JAVA_HOME JRE_HOME CLASS_PATH TOMCAT_PATH PATH
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

• 刷新配置文件

source /etc/profile

安装apr动态库

调用tomcat内置apr库安装

cd $TOMCAT_PATH/bin
tar -zxvf tomcat-native.tar.gz
cd ./tomcat-native-1.2.17-src/native
<!--动态库默认安装在/usr/local/apr/lib目录-->
./configure && make && make install

网上下载apr动态库安装

cd /usr/local/tomcat/bin
wget http://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-1.6.5.tar.gz
tar zxvf apr-1.6.5.tar.gz
cd apr-1.6.5
./configure --prefix=/usr/local/apr && make && make install

安装apr-iconv包

cd ../
wget http://mirror.bit.edu.cn/apache//apr/apr-iconv-1.2.2.tar.gz
tar zxvf apr-iconv-1.2.2.tar.gz
cd apr-iconv-1.2.2
./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr  && make  && make install

最后安装apr-util包，安装前请确保yum install expat-devel

cd ../
wget http://mirror.bit.edu.cn/apache//apr/apr-util-1.6.1.tar.gz
tar zxvf apr-util-1.6.1.tar.gz
cd apr-util-1.6.1

./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr --with-apr-iconv=/usr/local/apr-iconv/bin/apriconv && make  && make install 

在使用native的./configure命令时，要使用如下命令参数指定安装目录

./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/java/jdk1.8.0_144 --with-ssl=/usr/local/openssl

配置APR动态库

vim $TOMCAT_PATH/bin/catalina.sh

<!-- 加上下面代码 -->
JAVA_OPTS="$JAVA_OPTS -Djava.library.path=/usr/local/apr/lib"

配置server.xml

<!-- HTTP/1.1 -> org.apache.coyote.http11.Http11AprProtocol -->
<Connector port="8080" protocol="org.apache.coyote.http11.Http11AprProtocol" connectionTimeout="20000" redirectPort="8443"/>

<!-- 不想启用SSL 如果没有ssl的配置 但是又没有修改配置会出现错误：This function has not been implemented on this platform -->
<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="off" />

高并发配置

   <Executor name="tomcatThreadPool"
        namePrefix="HTTP-80-exec-"
        prestartminSpareThreads="true"
        maxProcessors="5000"
        maxQueueSize="100"
        minSpareThreads="50"
        maxIdleTime="10000" />
    
    <Connector port="80"
        connectionTimeout="20000"
        compression="on"
        redirectPort="8443"
        compressionMinSize="2048"
        maxThreads="500"
        maxSpareThreads="400"
        maxHttpHeaderSize ="102400"
        noCompressionUserAgents="gozilla,traviata"
        compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain,application/json,application/x-javascript"
        protocol="org.apache.coyote.http11.Http11NioProtocol"  
  executor="tomcatThreadPool" 
        minProcessors="50" 
        maxProcessors="5000" 
        acceptCount="100" 
        URIEncoding="UTF-8" />
  <!-- executor采用上面的共享线程池 -->
  <!-- minProcessors服务器启动时创建的处理请求的线程数 -->
  <!-- maxProcessors最大可以创建的处理请求的线程数 -->
  <!-- acceptCount指定当所有可以使用的处理请求的线程数都被使用时，可以放到处理队列中的请求数，超过这个数的请求将不予处理 -->

配置SSL

官方配置实例

<Connector port="80"
    maxHttpHeaderSize="8192"
    maxThreads="150"
    enableLookups="false" disableUploadTimeout="true"
    acceptCount="100" scheme="https" secure="true"
    SSLEnabled="true"
    SSLCertificateFile="${catalina.base}/conf/localhost.crt"
    SSLCertificateKeyFile="${catalina.base}/conf/localhost.key" />

需求jar包

存放到 tomcat/lib 目录下

<!-- 日志文件 -->
<!--log4j-->
wget http://www.apache.org/dist/logging/log4j/1.2.17/log4j-1.2.17.tar.gz

<!-- tomcat自带日志文件的配置 - tomcat/conf/logging.properties -->
<!-- 关闭日志文件方式如下 -->
1catalina.org.apache.juli.FileHandler.level = OFF
