Tar-zxvf apr-1.5.0.tar.gz

Cd apr-1.5.0

./Configure

Make

Make install

Installed in/usr/local/apr by default

Enter the bin directory of tomcat

Tar-zxvf tomcat-native.tar.gz

Cd tomcat-native-1.1.20-src/

Cd jni/native

./Configure -- with-apr =/usr/local/apr -- with-java-home = "/usr/lib/jvm/java-1.7.0" -- with-ssl = yes

Make

Make install

Installed on

/Usr/local/apr/lib

Cd/usr/lib
Ln-s/usr/local/apr/lib/libapr-1.so.0.5.0 lib-apr-1.so
Ln-s/usr/local/apr/lib/libapr-1.so.0.5.0 lib-apr-1.so.0
Ln-s/usr/local/apr/lib/libtcnative-1.so.0.1.20 libtcnative-1.so
Ln-s/usr/local/apr/lib/libtcnative-1.so.0.1.20 libtcnative-1.so

Or create the setenv. sh file in the bin directory of tomcat installation:
LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: $ CATALINA_HOME/lib
Export LD_LIBRARY_PATH
Check
In conf/server. xml, <Listener className = "org. apache. catalina. core. AprLifecycleListener" SSLEngine = "on"/> is enabled by default.

<Connector port = "8080" protocol = "org. apache. coyote. http11.Http11AprProtocol" maxThreads = "150" connectionTimeout = "20000" redirectPort = "8443">

If the configuration is successful, start tomcat and you will see the following information:

Org. apache. coyote. http11.Http11AprProtocol init
