纯记录 

 

#安装 Tokyo Cabinet

wget http://1978th.net/tokyocabinet/tokyocabinet-1.4.47.tar.gz
tar zxvf tokyocabinet-1.4.47.tar.gz
cd tokyocabinet-1.4.47
./configure --enable-off64
#32位系统需要 --enable-off64，以让它支持大于2GB的文件
make
make install
cd ..

#安装 lua
wget http://www.lua.org/ftp/lua-5.1.4.tar.gz
tar zxvf lua-5.1.4.tar.gz
cd lua-5.1.4
#要根据系统而定，直接make它会有提示
make linux
make install
ln -s /usr/local/bin/lua /usr/bin/lua
cd ..

#安装Tokyo Cabinet 的 lua 扩展
wget http://1978th.net/tokyocabinet/luapkg/tokyocabinet-lua-1.10.tar.gz
tar zxvf tokyocabinet-lua-1.10.tar.gz
cd tkoyocabinet-lua-1.10
./configure
make
make install
cd ..

#安装 Tokyo Tyrant
wget http://1978th.net/tokyotyrant/tokyotyrant-1.1.41.tar.gz
tar zxvf tokyotyrant-1.1.41.tar.gz
cd tokyotyrant-1.1.41
./configure --enable-lua --with-lua
make
make install
cd ../

mkdir -p /session/

#还需要一个 expire.lua 文件，这个文件用于定时将过期的 session 清理。代码如下：
cat > /session/expire.lua << "EOF" 
function expire()
local args = {}
local cdate = string.format("%d", _time())
table.insert(args, "addcond\0ts\0NUMLE\0" .. cdate)
table.insert(args, "out")
local res = _misc("search", args)
if not res then
_log("expiration was failed", 2)
end
end
EOF
