這里，之所以研究這個問題，是因為我們的生產系統Linux環境下的tomcat日志里面，啟動信息的地方有這么一個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
這個雖然對應有沒有什么影響，但是看到這個信息，總是有些不愉快。
關於APR是啥或者有什么好處，請參考這個官方文檔介紹Apache Portable Runtime (APR) based Native library for Tomcat
為了將這個警告或者提醒信息去除，其實也很簡單，只需要做幾步配置就好：
1. 安裝apr
2. 安裝apr-util
3. 安裝tomcat-native
首先，說下，我的環境信息：
1. Linux
[root@localhost bin]# uname -a Linux localhost.localdomain 3.10.0-229.el7.x86_64 #1 SMP Thu Jan 29 18:37:38 EST 2015 x86_64 x86_64 x86_64 GNU/Linux
2. Tomcat
[root@localhost bin]# pwd /opt/shihuc/apache-tomcat-7.0.64/bin [root@localhost bin]# ./version.sh Using CATALINA_BASE: /opt/shihuc/apache-tomcat-7.0.64 Using CATALINA_HOME: /opt/shihuc/apache-tomcat-7.0.64 Using CATALINA_TMPDIR: /opt/shihuc/apache-tomcat-7.0.64/temp Using JRE_HOME: /usr/java/jdk1.8.0_144 Using CLASSPATH: /opt/shihuc/apache-tomcat-7.0.64/bin/bootstrap.jar:/opt/shihuc/apache-tomcat-7.0.64/bin/tomcat-juli.jar Server version: Apache Tomcat/7.0.64 Server built: Aug 19 2015 17:18:06 UTC Server number: 7.0.64.0 OS Name: Linux OS Version: 3.10.0-229.el7.x86_64 Architecture: amd64 JVM Version: 1.8.0_144-b01 JVM Vendor: Oracle Corporation
接下來，進行三步走策略，完成APR的環境配置。
1. 安裝apr
在官網下載最新的apr，下載地址為http://mirrors.shu.edu.cn/apache//apr/apr-1.6.3.tar.gz
下載后，進行解壓，並進入到根目錄進行configure,make以及make install
[root@localhost apr-1.6.3]# pwd /opt/shihuc/apr-1.6.3
這個操作，比較簡單，不做過多描述。
2.安裝apr-util
在官網下載最新的apr-util,下載地址為http://mirrors.shu.edu.cn/apache//apr/apr-util-1.6.1.tar.gz
下載后，進行解壓，並進入到根目錄進行configure，make以及make install
[root@localhost apr-util-1.6.1]# pwd /opt/shihuc/apr-util-1.6.1 [root@localhost apr-util-1.6.1]# ./configure checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking target system type... x86_64-pc-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking for working mkdir -p... yes APR-util Version: 1.6.1 checking for chosen layout... apr-util checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed Applying apr-util hints file rules for x86_64-pc-linux-gnu checking for APR... no configure: error: APR could not be located. Please use the --with-apr option.
注意，這里報錯了，並且提醒了，要加--with-apr選項進行配置。意思是說，告知apr-util配置的時候apr的路徑在什么地方。

這次OK了，沒有再報錯。
3. 安裝tomcat-native
注意，我們的tomcat是tomcat7了，這個版本以及之后的版本，是不需要單獨下載tomcat-native的包的，在tomcat的bin目錄下，已經帶上了，我們只需要在這個目錄下進行解壓和安裝即可。
[root@localhost apache-tomcat-7.0.64]# cd bin/ [root@localhost bin]# ll 總用量 788 -rw-r--r--. 1 root root 28064 8月 20 2015 bootstrap.jar -rw-r--r--. 1 root root 13007 8月 20 2015 catalina.bat -rwxr-xr-x. 1 root root 20909 8月 20 2015 catalina.sh -rw-r--r--. 1 root root 1647 8月 20 2015 catalina-tasks.xml -rw-r--r--. 1 root root 24283 8月 20 2015 commons-daemon.jar -rw-r--r--. 1 root root 204944 8月 20 2015 commons-daemon-native.tar.gz -rw-r--r--. 1 root root 2040 8月 20 2015 configtest.bat -rwxr-xr-x. 1 root root 1922 8月 20 2015 configtest.sh -rwxr-xr-x. 1 root root 7888 8月 20 2015 daemon.sh -rw-r--r--. 1 root root 2091 8月 20 2015 digest.bat -rwxr-xr-x. 1 root root 1965 8月 20 2015 digest.sh -rw-r--r--. 1 root root 3430 8月 20 2015 setclasspath.bat -rwxr-xr-x. 1 root root 3547 8月 20 2015 setclasspath.sh -rw-r--r--. 1 root root 2020 8月 20 2015 shutdown.bat -rwxr-xr-x. 1 root root 1902 8月 20 2015 shutdown.sh -rw-r--r--. 1 root root 2022 8月 20 2015 startup.bat -rwxr-xr-x. 1 root root 1904 8月 20 2015 startup.sh -rw-r--r--. 1 root root 38217 8月 20 2015 tomcat-juli.jar -rw-r--r--. 1 root root 388787 8月 20 2015 tomcat-native.tar.gz -rw-r--r--. 1 root root 4021 8月 20 2015 tool-wrapper.bat -rwxr-xr-x. 1 root root 5024 8月 20 2015 tool-wrapper.sh -rw-r--r--. 1 root root 2026 8月 20 2015 version.bat -rwxr-xr-x. 1 root root 1908 8月 20 2015 version.sh
將這個tomcat-native.tar.gz解壓並進入到native目錄下，進行configure，make以及make install。因為，我們的tomcat配置中，涉及apr的地方，啟用了SSL，所以，我們的環境里面，必須要有SSL的支持能力。

下面的省略了。。。
所以SSL的環境必須要有，檢查后發現，我的Linux系統，因為之前其他項目的需要，已經安裝了openssl了，通過rpm查看。
[root@localhost native]# rpm -qa|grep openssl openssl-devel-1.0.2k-8.el7.x86_64 openssl098e-0.9.8e-29.el7_0.2.x86_64 openssl-1.0.2k-8.el7.x86_64 openssl-libs-1.0.2k-8.el7.x86_64 [root@localhost native]#
系統當前已經安裝有openssl了，版本為openssl-devel-1.0.2k-8.el7.x86_64。
或者通過這種方式，也可以查看是否安裝openssl，直接執行openssl，看是否存在。那么openssl的安裝路徑是啥呢？
[root@localhost native]# which openssl /home/anaconda2/bin/openssl
下面檢查tomcat-native的JDK環境：
[root@localhost native]# echo $JAVA_HOME /usr/java/jdk1.8.0_144
tomcat-native的依賴都有了，接下來，就是直接安裝操作了。
[root@localhost native]# ./configure --with-apr=/usr/local/apr --with-ssl=/home/anaconda2/bin --with-java-home=/usr/java/jdk1.8.0_144 checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking for working mkdir -p... yes Tomcat Native Version: 1.1.33 checking for chosen layout... tcnative checking for APR... yes setting CC to "gcc" setting CPP to "gcc -E" checking for JDK location (please wait)... /usr/java/jdk1.8.0_144 checking Java platform... checking Java platform... checking for sablevm...

接下來，就執行make以及make install了。

所有的安裝操作都OK了，接下來，還有一點，注意，不要遺忘了配置環境變量，就是APR的環境變量。
修改/etc/profile,然后做下面的紅色內容的新增，寫上apr的安裝路徑：
export LD_LIBRARY_PATH=/usr/local/apr/lib:/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH
然后，source一下/etc/profile.啟用這個新的環境配置。
所有的操作都結束了，最后就是驗證是否APR生效。很簡單，只需要將tomcat重啟一下，查看catalina.out的日志，看看是否存在開篇提到的APR的那個提醒信息即可。我的環境配置，安裝上述步驟，這個APR的提醒信息已經解除，的確不存在了。
下面對比一下，沒有做上述APR配置和做了這個配置的啟動日志有什么不同：
沒有配置APR的日志：

總結：
1. APR這個就算沒有配置，也不影響tomcat的正常使用，無非就是性能稍微差點。
2. 在tomcat-native的configure操作中，若不正確配置--with-ssl這個選項的話，其他的就算都配置好了，依然會出現開篇提到的APR提醒信息。也就是說APR功能不啟用。
3.關於tomcat啟動日志中，下面的這些警告信息，我沒有找到最終的解釋，但是個人基於http://tomcat.apache.org/tomcat-7.0-doc/config/http.html#Standard_Implementation的介紹，認為是這些警告的信息涉及到的配置在tomcat7里面已經過期了，也就是說找不到相關的配置，即使有這個警告，也沒什么問題。若有高人對這個有確切的了解，還請分享下。
