Linux下Tomcat8.0.44配置使用Apr

luowei · 发表于 2017-7-27 18:03:30

听说Apr可以提高tomcat很多的性能，配置具体如下

1.安装apr 1.5.2

复制代码

2.安装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

复制代码

3.如果没有安装openssl的请安装下openssl，已经安装的继续下一步

4.安装 tomcat-native组件，发现在tomcat8.0.44的bin目录下面已经有相关文件tomcat-native.tar.gz
解压后得到tomcat-native-1.2.12-src文件夹

[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

复制代码

5.tomcat配置，默认tomcat8.0.44是启用Apr的，在Listener结点配置

<Listener SSLEngine="on" className="org.apache.catalina.core.AprLifecycleListener"/>

复制代码

重启tomcat服务后出现一个问题，表示还没有成功使用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

复制代码

解决方法：

在/usr/java/packages/lib/amd64目录下面创建/usr/local/apr/lib/libtcnative-1.so.0.2.12的链接

[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

复制代码

6.重新启动tomcat，如果显示如下信息就表示已经配置成功了。

27-Jul-2017 16:16:29.479 INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent Loaded APR based Apache
