Tomcat里面的APR配置问题研究
这里，之所以研究这个问题，是因为我们的生产系统Linux环境下的tomcat日志里面，启动信息的地方有这么一个WARNING。
INFO: 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
这个虽然对应有没有什么影响，但是看到这个信息，总是有些不愉快。
关于APR是啥或者有什么好处，请参考这个官方文档介绍Apache Portable Runtime (APR) based Native library for Tomcat
为了将这个警告或者提醒信息去除，其实也很简单，只需要做几步配置就好：
1. 安装apr
2. 安装apr-util
3. 安装tomcat-native
首先，说下，我的环境信息：
1. Linux
[root@localhost bin]# uname -a
Linux localhost.localdomain 3.10.-.el7.x86_64 # SMP Thu Jan :: EST x86_64 x86_64 x86_64 GNU/Linux
2. Tomcat
[root@localhost bin]# pwd
/opt/shihuc/apache-tomcat-7.0./bin
[root@localhost bin]# ./version.sh
Using CATALINA_BASE: /opt/shihuc/apache-tomcat-7.0.
Using CATALINA_HOME: /opt/shihuc/apache-tomcat-7.0.
Using CATALINA_TMPDIR: /opt/shihuc/apache-tomcat-7.0./temp
Using JRE_HOME: /usr/java/jdk1..0_144
Using CLASSPATH: /opt/shihuc/apache-tomcat-7.0./bin/bootstrap.jar:/opt/shihuc/apache-tomcat-7.0./bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.
Server built: Aug :: UTC
Server number: 7.0.64.0
OS Name: Linux
OS Version: 3.10.-.el7.x86_64
Architecture: amd64
JVM Version: 1.8.0_144-b01
JVM Vendor: Oracle Corporation
接下来，进行三步走策略，完成APR的环境配置。
1. 安装apr
在官网下载最新的apr，下载地址为http://mirrors.shu.edu.cn/apache//apr/apr-1.6.3.tar.gz
下载后，进行解压，并进入到根目录进行configure,make以及make install
[root@localhost apr-1.6.]# pwd
/opt/shihuc/apr-1.6.
这个操作，比较简单，不做过多描述。
2.安装apr-util
在官网下载最新的apr-util,下载地址为http://mirrors.shu.edu.cn/apache//apr/apr-util-1.6.1.tar.gz
下载后，进行解压，并进入到根目录进行configure，make以及make install
[root@localhost apr-util-1.6.]# pwd
/opt/shihuc/apr-util-1.6.
[root@localhost apr-util-1.6.]# ./configure

注意，这里报错了，并且提醒了，要加--with-apr选项进行配置。意思是说，告知apr-util配置的时候apr的路径在什么地方。

这次OK了，没有再报错。
3. 安装tomcat-native
注意，我们的tomcat是tomcat7了，这个版本以及之后的版本，是不需要单独下载tomcat-native的包的，在tomcat的bin目录下，已经带上了，我们只需要在这个目录下进行解压和安装即可。
[root@localhost apache-tomcat-7.0.]# cd bin/
[root@localhost bin]# ll
总用量
-rw-r--r--. root root 8月 bootstrap.jar
-rw-r--r--. root root 8月 catalina.bat
-rwxr-xr-x. root root 8月 catalina.sh
-rw-r--r--. root root 8月 catalina-tasks.xml
-rw-r--r--. root root 8月 commons-daemon.jar
-rw-r--r--. root root 8月 commons-daemon-native.tar.gz
-rw-r--r--. root root 8月 configtest.bat

-rw-r--r--. root root 8月 tomcat-juli.jar
-rw-r--r--. root root 8月 tomcat-native.tar.gz
-rw-r--r--. root root 8月 tool-wrapper.bat
-rwxr-xr-x. root root 8月 tool-wrapper.sh
-rw-r--r--. root root 8月 version.bat
-rwxr-xr-x. root root 8月 version.sh
将这个tomcat-native.tar.gz解压并进入到native目录下，进行configure，make以及make install。因为，我们的tomcat配置中，涉及apr的地方，启用了SSL，所以，我们的环境里面，必须要有SSL的支持能力。

所以SSL的环境必须要有，检查后发现，我的Linux系统，因为之前其他项目的需要，已经安装了openssl了，通过rpm查看。
[root@localhost native]# rpm -qa|grep openssl
openssl-devel-1.0.2k-.el7.x86_64
openssl098e-0.9.8e-.el7_0..x86_64
openssl-1.0.2k-.el7.x86_64
openssl-libs-1.0.2k-.el7.x86_64
[root@localhost native]#
系统当前已经安装有openssl了，版本为openssl-devel-1.0.2k-8.el7.x86_64。
或者通过这种方式，也可以查看是否安装openssl，直接执行openssl，看是否存在。那么openssl的安装路径是啥呢？
[root@localhost native]# which openssl
/home/anaconda2/bin/openssl
下面检查tomcat-native的JDK环境：
[root@localhost native]# echo $JAVA_HOME
/usr/java/jdk1..0_144
tomcat-native的依赖都有了，接下来，就是直接安装操作了。
[root@localhost native]# ./configure --with-apr=/usr/local/apr --with-ssl=/home/anaconda2/bin --with-java-home=/usr/java/jdk1.8.0_144

setting TCNATIVE_LDFLAGS to "-L/home/anaconda2/bin/lib -Wl,-rpath,/home/anaconda2/bin/lib -lssl -lcrypto"
adding "-DHAVE_OPENSSL" to CFLAGS
setting TCNATIVE_LIBS to ""
setting TCNATIVE_LIBS to " /usr/local/apr/lib/libapr-1.la -lrt -lcrypt -lpthread -ldl"
configure: creating ./config.status

接下来，就执行make以及make install了。

Libraries have been installed in:
/usr/local/apr/lib If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the 'LD_RUN_PATH' environment variable
during linking
- use the '-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to '/etc/ld.so.conf' See any operating system documentation about shared libraries for
more information, such as the ld() and ld.so() manual pages.

[root@localhost native]#
所有的安装操作都OK了，接下来，还有一点，注意，不要遗忘了配置环境变量，就是APR的环境变量。
修改/etc/profile,然后做下面的红色内容的新增，写上apr的安装路径：
export LD_LIBRARY_PATH=/usr/local/apr/lib:/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH
然后，source一下/etc/profile.启用这个新的环境配置。
所有的操作都结束了，最后就是验证是否APR生效。很简单，只需要将tomcat重启一下，查看catalina.out的日志，看看是否存在开篇提到的APR的那个提醒信息即可。我的环境配置，安装上述步骤，这个APR的提醒信息已经解除，的确不存在了。
下面对比一下，没有做上述APR配置和做了这个配置的启动日志有什么不同：

总结：
1. APR这个就算没有配置，也不影响tomcat的正常使用，无非就是性能稍微差点。
2. 在tomcat-native的configure操作中，若不正确配置--with-ssl这个选项的话，其他的就算都配置好了，依然会出现开篇提到的APR提醒信息。也就是说APR功能不启用。
3.关于tomcat启动日志中，下面的这些警告信息，我没有找到最终的解释，但是个人基于http://tomcat.apache.org/tomcat-7.0-doc/config/http.html#Standard_Implementation的介绍，认为是这些警告的信息涉及到的配置在tomcat7里面已经过期了，也就是说找不到相关的配置，即使有这个警告，也没什么问题。若有高人对这个有确切的了解，还请分享下。
