lua-zlib包用于nginx上对gzip数据进行解压缩，可将lua-zlib编译成一个动态链接库zlib.so，便于lua引用。

1. 安装

1.1 检查是否安装zlib

$ rpm -qa zlib
zlib-1.2.3-29.el6.x86_64

1.2 安装cmake

检查gcc, g++， make是否安装

gcc -v
g++ -v
make -v

若未安装，则：yum install -y gcc gcc-c++ make automake

安装cmake

cd /usr/local
wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz
tar -xvzf cmake-2.8.10.2.tar.gz
cd cmake-2.8.10.2
./bootstrap
gmake
gmake install检查cmake是否安装成功：
$ cmake --version
cmake version 2.8.10.2

1.3 安装lua-zlib

(1)download
cd /usr/local
wget https://github.com/brimworks/lua-zlib/archive/master.zip
unzip lua-zlib-master.zip
(2)cmake
cd /usr/local/lua-zlib-master
cmake -DLUA_INCLUDE_DIR=/usr/local/openresty/luajit/include/luajit-2.1 -DLUA_LIBRARIES=/usr/local/openresty/luajit/lib -DUSE_LUAJIT=ON -DUSE_LUA=OFF
make
cp zlib.so /usr/local/openresty/lualib/zlib.so

2. zlib包使用
