CentOS 7 Tomcat 8 9 基于APR库性能优化

Posted 2020-12-30 大魔王

Tomcat可以使用Apache Portable Runtime来提供卓越的性能及可扩展性，更好地与本地服务器技术的集成。Apache Portable Runtime是一个高度可移植的库，位于Apache HTTP Server 2.x的核心。APR有许多用途，包括访问高级IO功能（如sendfile，epoll和OpenSSL），操作系统级功能（随机数生成，系统状态等）以及本地进程处理（共享内存，NT管道和Unix套接字）

这些功能不仅仅是一个后端集中的技术，还可以让Tomcat成为通用的网络服务器，可以实现与本地的其他Web技术更好的集成，并使Java成为一个完整的网络服务器平台

官方要求 ：

APR 1.2+ development headers (libapr1-dev package)
OpenSSL 1.0.2+ development headers (libssl-dev package)
JNI headers from Java compatible JDK 1.4+
GNU development environment (gcc, make)

配置server.xml

[[email protected] native]# cd /usr/local/tomcat/conf/
[[email protected] conf]# vim server.xml 
<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
# 修改为
<Connector port="8080" protocol="org.apache.coyote.http11.Http11AprProtocol"
               connectionTimeout="20000"
               redirectPort="8443" />     
================================================================================
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
# 修改为
<Connector port="8009"         
                protocol="org.apache.coyote.ajp.AjpAprProtocol" 
                redirectPort="8443" />
