In most cases we recomend using the mod_proxy \/apache<\/a> combination as a frontend to tomcat. However for those looking to squeeze extra performance out of a bare tomcat installation the following may be useful<\/p><\/blockquote>\n\n\n\n

Apache Portable Runtime (APR) and Tomcat<\/p><\/blockquote>\n\n\n\n

Per http:\/\/apr.apache.org\/<\/a> Tomcat can use the Apache Portable Runtime to provide superior scalability, performance, and better integration with native server technologies.<\/p><\/blockquote>\n\n\n\n

Installing the JNI wrappers for APR used by Tomcat (libtcnative)<\/p><\/blockquote>\n\n\n\n

You can now grab the latest tcnative wrapper from http:\/\/tomcat.apache.org\/native-doc\/<\/a> and drop that into the tomcat libs folder (eg \/usr\/local\/tomcat\/libs).<\/p><\/blockquote>\n\n\n\n

We recommend you use the package install methods shown on the above link to obtain the libraries noted. Those should be available using either yum or apt-get depending on your installed distribution.<\/p><\/blockquote>\n\n\n\n

You should be able to just grab the jar file and drop that into the tomcat libs folder (check in case it is already present).<\/p><\/blockquote>\n\n\n\n

Remeber to restart tomcat to make that load the updated\/new libraries. And check in the tomcat logs to confirm they have been imported correctly.<\/p><\/blockquote>\n<\/div><\/div>\n\n\n\n

Nota recordatoria; De la documentaci\u00f3 de Tomcat: <\/h6>\n\n\n\n

CATALINA_HOME and CATALINA_BASE<\/p>

Throughout the documentation, there are references to the two following properties:<\/p>

CATALINA_HOME<\/strong>: Represents the root of your Tomcat installation, for example \/home\/tomcat\/apache-tomcat-9.0.10<\/code> or C:\\Program Files\\apache-tomcat-9.0.10<\/code>.<\/p>

CATALINA_BASE<\/strong>: Represents the root of a runtime configuration of a specific Tomcat instance. If you want to have multiple Tomcat instances on one machine, use the CATALINA_BASE<\/code> property.<\/p>

If you set the properties to different locations, the CATALINA_HOME location contains static sources, such as .jar<\/code> files, or binary files. The CATALINA_BASE location contains configuration files, log files, deployed applications, and other runtime requirements.<\/p><\/blockquote>\n\n\n\n

En el cas de Debian:<\/p>\n\n\n\n
