Compile - NginX under Linux

== Tips for compiling NginX ==

After downloading nginx tarball you also need:
- zlib.tar.gz
- openssl.tar.gz


1 - make and install zlib
2 - uncompress openssl tarball
3 - Configure nginx script:
   - ./configure \
      --with-http_ssl_module --with-openssl=../openssl-uncompress-dir \
      --prefix=/srv/your-dir
4 - make
5 - make install



 That should give a working nginX server ;)

Linux - diags commands, Get hard / soft Info

Here are some commands that we can use to obtain info from a Linux host:


# dmesg              -- show bootup messages / detected hardware

#  top                -- show cpu/mem/swap usage and running processes
# mii-tool           -- show nic infos
# du -xh | sort      -- show disk usage

# ps -exfcl          -- show processes running - list 
# rpm -qa            -- show packages.version installed - (redhat/fedora)
# cat /etc/fstab     -- show filesystem table

# cat /proc/cpuinfo  -- show cpu information
# cat /proc/devices  -- show devices ( /proc "filesystem" shows lots of info)
# cat /proc/meminfo  -- show memory


The list continues...i will add some more later

Linux Basics - 1

== Linux basic commands ==

The kernel: Monolithic or Modular

A monolithic kernel is one which has support for all hardware, network, and filesystem compiled into a single image file.

A modular kernel is one which has some drivers compiled as object files, which the kernel can load and remove on demand. Loadable modules are kept in /lib/modules.

-------Commands that can help --------------------

# lsmod - list currently loaded modules

# rmmod - remove a single module

# insmod - insert a single module

# depmod - create the database of module dependencies modules.dep

# modprobe -insert a module and dependencies listed in modules.dep

# modinfo - list information about the author, license type and module parameters
