Tomcat9 运行模式更改为APR模式附安装脚本

Tomcat支持三种接收请求的处理方式：BIO、NIO、APR

软件版本: Tomcat9.0.85

操作系统: Rockylinux8.9

 BIO由于每个请求都要创建一个线程来处理，线程开销比较大，不能再高并发的场景，性能也是最低的。
NIO是一个基于缓冲区、并能提供非阻塞I/O操作的Java API，比传统的bio更好的并发性能。
APR（Apache Portable Run-time libraries）简单理解，就是从操作系统级别解决异步IO问题，大幅度的提高服务器的处理和响应性能， 也是Tomcat运行高并发应用的首选模式。

安装依赖

 yum install -y apr-devel openssl-devel gcc make expat-devel libtool

安装软件

 cd /usr/local/src
wget https://mirrors.cloud.tencent.com/apache/apr/apr-1.6.5.tar.gz
tar xf apr-1.6.5.tar.gz
cd apr-1.6.5/
./configure --prefix=/usr/local/apr
make && make install
cd /usr/local/src
wget https://mirrors.cloud.tencent.com/apache/apr/apr-iconv-1.2.2.tar.gz
tar xf apr-iconv-1.2.2.tar.gz
cd apr-iconv-1.2.2/
./configure --with-apr=/usr/local/apr --prefix=/usr/local/apr-iconv
make && make install
cd /usr/local/src
wget https://mirrors.cloud.tencent.com/apache/apr/apr-util-1.6.3.tar.gz

cd apr-util-1.6.3/
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr --with-apr-iconv=/usr/local/apr-iconv/bin/apriconv

wget https://mirrors.cloud.tencent.com/apache/tomcat/tomcat-connectors/native/1.2.39/source/tomcat-native-1.2.39-src.tar.gz
tar xf tomcat-native-1.2.39-src.tar.gz
./configure --prefix=/usr/local/tomcat-native --with-apr=/usr/local/apr --with-ssl=yes
make && make install
echo -e 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib\nexport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/tomcat-native/lib:$CATALINA_HOME/lib\nexport LD_RUN_PATH=$LD_RUN_PATH:/usr/local/apr/lib' >> /etc/profile
source /etc/profile

启用 Tomcat Native Library(上面已配置,这一步可不做)

在 $CATALINA_HOME/bin 目录下新建 setenv.sh:

 LD_LIBRARY_PATH=/usr/local/tomcat-native/lib:$CATALINA_HOME/lib
export LD_LIBRARY_PATH

tomcat的server.xml需要更换成以下配置

 <Executor name="tomcatThreadPool" 
         namePrefix="catalina-exec-"
         maxThreads="300" 
         minSpareThreads="30"/>
 
<Connector    executor="tomcatThreadPool" 
              port="8080" 
              protocol="org.apache.coyote.http11.Http11AprProtocol"
              connectionTimeout="20000"
              redirectPort="8443"
              acceptCount="900"
              disableUploadTimeout="true"
              URIEncoding="UTF-8"
              enableLookups="false"
              compression="on"
              compressionMinSize="1024"
              />

/usr/local/tomcat/bin/startup.sh

查看端口情况

[root@slave bin]# netstat -tulnp | grep 8080
tcp6 0 0 :::8080 :::* LISTEN 84309/java
