聽(tīng)說(shuō)Apr可以提高tomcat很多的性能，配置具體如下
1.安裝apr 1.5.2
[root@ecs-3c46 ]# cd /usr/local/src[root@ecs-3c46 src]# wget http://apache.fayea.com//apr/apr-1.5.2.tar.gz[root@ecs-3c46 src]# tar -xzvf apr-1.5.2.tar.gz[root@ecs-3c46 src]# cd apr-1.5.2[root@ecs-3c46 apr-1.5.2]# ./configure --prefix=/usr/local/apr[root@ecs-3c46 apr-1.5.2]# make[root@ecs-3c46 apr-1.5.2]# make install
2.安裝apr-util-1.5.4
[root@ecs-3c46 ]# cd /usr/local/src[root@ecs-3c46 src]# wget http://mirrors.hust.edu.cn/apache//apr/apr-util-1.5.4.tar.gz[root@ecs-3c46 src]# tar -xzvf apr-util-1.5.4.tar.gz[root@ecs-3c46 src]# cd apr-util-1.5.4[root@ecs-3c46 apr-util-1.5.4]# ./configure --prefix=/usr/local/apr[root@ecs-3c46 apr-util-1.5.4]# make[root@ecs-3c46 apr-util-1.5.4]# make install
3.如果沒(méi)有安裝openssl的請(qǐng)安裝下openssl，已經(jīng)安裝的繼續(xù)下一步
4.安裝 tomcat-native組件，發(fā)現(xiàn)在tomcat8.0.44的bin目錄下面已經(jīng)有相關(guān)文件tomcat-native.tar.gz
解壓后得到tomcat-native-1.2.12-src文件夾
[root@ecs-3c46 bin]# tar -xzvf tomcat-native.tar.gz[root@ecs-3c46 bin]# cd tomcat-native-1.2.12-src/native[root@ecs-3c46 native]# ./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/java/jdk1.7.0_80 --with-ssl=/usr/local/openssl --prefix=/usr/local/tomcat/apache-tomcat-8.0.44[root@ecs-3c46 native]# make[root@ecs-3c46 native]# make install
5.tomcat配置，默認(rèn)tomcat8.0.44是啟用Apr的，在Listener結(jié)點(diǎn)配置
<Listener SSLEngine="on" className="org.apache.catalina.core.AprLifecycleListener"/>
重啟tomcat服務(wù)后出現(xiàn)一個(gè)問(wèn)題，表示還沒(méi)有成功使用Apr
27-Jul-2017 15:50:13.488 INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
解決方法：
在/usr/java/packages/lib/amd64目錄下面創(chuàng)建/usr/local/apr/lib/libtcnative-1.so.0.2.12的鏈接
[root@ecs-3c46 native]# cd /usr/java/[root@ecs-3c46 java]# mkdir packages/[root@ecs-3c46 java]# cd packages/[root@ecs-3c46 packages]# mkdir lib[root@ecs-3c46 packages]# cd lib[root@ecs-3c46 lib]# mkdir amd64[root@ecs-3c46 lib]# cd amd64[root@ecs-3c46 amd64]# ln -s /usr/local/apr/lib/libtcnative-1.so.0.2.12 libtcnative-1.so[root@ecs-3c46 amd64]# ln -s /usr/local/apr/lib/libtcnative--1.so.0.2.12 libtcnative-1.so.0
6.重新啟動(dòng)tomcat，如果顯示如下信息就表示已經(jīng)配置成功了。
27-Jul-2017 16:16:29.479 INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent Loaded APR based Apache Tomcat Native library 1.2.12 using APR version 1.5.2.27-Jul-2017 16:16:29.479 INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true].27-Jul-2017 16:16:29.491 INFO [main] org.apache.catalina.core.AprLifecycleListener.initializeSSL OpenSSL successfully initialized (OpenSSL 1.0.2l 25 May 2017)
以上這篇Linux下Tomcat8.0.44配置使用Apr的方法就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持VEVB武林網(wǎng)。
