| + | paraFetch fetches files behind an HTTP server, hence we use [[http://nginx.org/|nginx]] since it is relatively easy to install without root. | ||
| + | |||
| + | <code> | ||
| + | mkdir ~/nginx | ||
| + | cd ~/nginx | ||
| + | wget http://nginx.org/download/nginx-1.0.0.tar.gz | ||
| + | tar zxvf nginx-1.0.0.tar.gz | ||
| + | cd nginx-1.0.0/ | ||
| + | ./configure --prefix=$HOME/nginx --without-http_rewrite_module --without-http-cache | ||
| + | make | ||
| + | make install | ||
| + | </code> | ||
| + | |||
| + | Edit ~/nginx/conf/nginx.conf to use port 8080. | ||
| + | |||
| + | In order to use more than 50 streams you must edit the paraFetch source and recompile. To do this for x86_64, with 600 streams: | ||
| + | |||
| + | 1. Download the kent source | ||
| + | <code> | ||
| + | git clone git://genome-source.cse.ucsc.edu/kent.git | ||
| + | </code> | ||
| + | |||
| + | |||
| + | 2. Edit lines 1804-1808 in "kent/src/lib/net.c": | ||
| + | |||
| + | <code> | ||
| + | if (numConnections > PARCONN)/* ignore high values for numConnections */ | ||
| + | { | ||
| + | warn("Currently maximum number of connections is %d. You requested %d. Will proceed with %d on %s",PARCONN, numConnections, PARCONN, url); | ||
| + | numConnections = PARCONN; | ||
| + | } | ||
| + | </code> | ||
| + | |||
| + | 3. Add a #define at the top of "kent/src/lib/net.c": | ||
| + | |||
| + | <code> | ||
| + | #define PARCONN 600 /*This is the maximum no. of parallel streams supported*/ | ||
| + | </code> | ||
| + | |||
| + | 4. Compile the common libraries for x86_64 (jkweb.a): | ||
| + | |||
| + | <code> | ||
| + | cd kent/src/lib/ | ||
| + | make x86_64/jkweb.a | ||
| + | </code> | ||
| + | |||
| + | 5. Compile paraFetch: | ||
| + | |||
| + | <code> | ||
| + | cd kent/src/utils/paraFetch/ | ||
| + | make | ||
| + | </code> | ||
| + | |||
| + | 6. Copy from your bin: | ||
| + | |||
| + | <code> | ||
| + | cp ~/bin/x86_64/paraFetch ~/ | ||
| + | </code> | ||
| + | |||
