Tomcat 性能优化,使用Apache的APR

一、安装apr,apr-iconv,apr-util

1. 安装apr(版本 apr-1.5.2)

# ./configure

# make;make install

2. 安装apr-iconv(版本 apr-iconv-1.2.1)

# ./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr

# make;make install

3. 安装apr-util(版本 apr-util-1.5.4)

# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr

# make;make install

二、配置Tomcat支持apr

2.1 安装 tomcat-native.tar.gz

这个包是Apache官网tomcat自带的,位置在 /usr/local/tomcat/bin目录下

# tar zxf tomcat-native.tar.gz

当前目录下生成 tomcat-native-1.1.30-src的目录

# cd tomcat-native-1.1.30-src/jni/native

# ./configure --with-apr=/usr/local/apr --with-java-home=/jdk1.6.0_29

# make;make install

添加/usr/local/apr/lib到 ld.so.conf文件

# vi /etc/ld.so.conf

include ld.so.conf.d/*.conf
/usr/local/apr/lib

保存

# ldconfig  使生效

2.2 配置tomcat启动时支持apr

# vi bin/catalina.sh

JAVA_OPTS="-server -Xms1024m -Xmx3072m -XX:PermSize=128M -XX:MaxPermSize=256m -XX:ParallelGCThreads=4 -XX:+UseNUMA"
CATALINA_OPTS=-Djava.library.path=/usr/local/apr/lib

启动tomcat

# bin/startup.sh

查看启动日志

tail logs/catalina.out

Jun 4, 2015 3:45:41 PM org.apache.coyote.ajp.AjpAprProtocol start
INFO: Starting Coyote AJP/1.3 on ajp-18009
Jun 4, 2015 3:45:41 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 5100 ms

停止tomcat时,日志中有下面内容表示停止成功

Jun 4, 2015 3:51:29 PM org.apache.coyote.http11.Http11AprProtocol destroy
INFO: Stopping Coyote HTTP/1.1 on http-18080
Jun 4, 2015 3:51:29 PM org.apache.coyote.http11.Http11AprProtocol destroy
INFO: Stopping Coyote HTTP/1.1 on http-8443
Jun 4, 2015 3:51:29 PM org.apache.coyote.ajp.AjpAprProtocol destroy
INFO: Stopping Coyote AJP/1.3 on ajp-18009

至此,ARP与tomcat结合完成。
