dependent packages are pre-installed into the /local Drive

1. Gzip module requires zlib library

2. Rewrite module requires Pcre library

3. SSL support requires OpenSSL library

Hard day, to catch the week 51 group of foodie colleagues called to eat hot pot

finish the document very late, and despite the intensity of the work each day, I would like to make progress with you. Hehe every day adhere to progress a little, insist on sharing a little.

follow up the other modules, what is the problem please do not mean to point out, together to improve. So far our common,service,application modules have all been completed, Of course, the follow-up will have some in-depth supplement, welcome everyone and the technical enthusiasts join our QQ Group 262407268, build our "Chinanetcloud Smart city"

At present, has completed three relatively small modules: common, service, application in fact, to achieve high performance inside there is a lot of content to learn to accumulate, follow-up will do to supplement. Next we should share the Data Warehouse section, first relational database Oracle, MySQL and then non-relational database mogondb, Redis, hbase, finally we open the path of distributed computing Hadoop, mainly for data analysis and processing. Here we will mention a collection of the production of the engine: sphinx+ Chinese word coreseek, will also do a log analysis of the architecture Splunk products. Together to build our "Chinanetcloud smart city".
Please consciously revise the notes, thank you. Affirm that this group is a community of public welfare, we are willing to undertake some architectural design, construction and consulting business, for you and your business to improve the business structure.
