1.安装LuaJIT-2.0.4
链接：
http://luajit.org/download.html
tar -xf LuaJIT-2.0.4.tar.gz cd LuaJIT-2.0.4 make PREFIX=/usr/local/luajit make install PREFIX=/usr/local/luajit
2.修改环境变量
vim /etc/profile export LUAJIT_LIB=/usr/local/luajit/lib export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0 source /etc/profile
3.下载nginx lua模块
ngx_devel_kit 链接：https://github.com/simpl/ngx_devel_kit/tags
lua-nginx-module 链接：https://github.com/openresty/lua-nginx-module/tags
4.编译nginx 增加支持模块
cd /tmp/soft/ tar -xf ngx_devel_kit-0.3.0.tar.gz tar -xf lua-nginx-module-0.10.5.tar.gz
4.1.编译nginx
tar -xf nginx-1.9.14.tar.gz cd nginx-1.9.14 ./configure \ --prefix=/app/local/nginx \ --pid-path=/app/local/nginx \ --user=nginx \ --group=nginx \ --with-threads \ --with-file-aio \ --with-http_ssl_module \ --with-http_v2_module \ --with-http_addition_module \ --with-http_sub_module \ --with-http_dav_module \ --with-http_flv_module \ --with-http_mp4_module \ --with-http_perl_module \ --with-mail \ --with-http_gzip_static_module \ --with-http_auth_request_module \ --with-http_random_index_module \ --with-http_secure_link_module \ --with-http_degradation_module \ --with-http_slice_module \ --with-http_stub_status_module \ --with-http_perl_module \ --with-zlib=/tmp/soft/zlib-1.2.8 \ --with-stream \ --with-stream_ssl_module \ --with-pcre=/tmp/soft/pcre-8.37 \ --with-openssl=/tmp/soft/openssl-1.0.2 \ --with-libatomic \ --add-module=/tmp/soft/ngx_log_if-master \ --add-module=/tmp/soft/ngx_devel_kit-0.3.0 \ --add-module=/tmp/soft/lua-nginx-module-0.10.5 make
5.备份原有的程序及增加链接
mv /app/local/nginx/sbin/nginx /app/local/nginx/sbin/nginx.0729 cp ./objs/nginx /app/local/nginx/sbin/ ln -s /usr/local/lib/libpcre.so.1 /lib64/libpcre.so.1 ln -s /usr/local/luajit/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2
6.查看模块
# /app/local/nginx/sbin/nginx -V nginx version: nginx/1.9.14 built by gcc 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) built with OpenSSL 1.0.2 22 Jan 2015 TLS SNI support enabled configure arguments: --prefix=/app/local/nginx --pid-path=/app/local/nginx --user=nginx --group=nginx --with-threads --with-file-aio --with-http_ssl_module --with-http_v2_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_perl_module --with-mail --with-http_gzip_static_module --with-http_auth_request_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module --with-zlib=/tmp/soft/zlib-1.2.8 --with-stream --with-stream_ssl_module --with-pcre=/tmp/soft/pcre-8.37 --with-openssl=/tmp/soft/openssl-1.0.2 --with-libatomic --add-module=/tmp/soft/ngx_log_if-master --add-module=/tmp/soft/ngx_devel_kit-0.3.0 --add-module=/tmp/soft/lua-nginx-module-0.10.5
7.nginx 修改为json格式
修改很简单，如下:
log_format ng_json '{'
'"http_cdn_src_ip":"$http_cdn_src_ip",'
'"time_local": "$time_local",'
'"request":"$request",'
'"status":"$status",'
'"body_bytes_sent":"$body_bytes_sent",'
'"request_body":"$request_body",'
'"content_length":"$content_length",'
'"http_referer":"$http_referer",'
'"http_user_agent":"$http_user_agent",'
'"http_x_forwarded_for":"$http_x_forwarded_for",'
'"remote_addr":"$remote_addr",'
'"upstream_response_time":"$upstream_response_time",'
'"request_time":"$request_time",'
'"http_x_trace_code":"$http_x_trace_code"}
}';
查看生成的json：
{
"http_cdn_src_ip": "-",
"time_local": "29/Jul/2016:03:01:02 +0800",
"request": "GET /q.gif?platform=pc&category=player&action=bufferEmpty&t=1469732461170&loc=/star/3459038 HTTP/1.1",
"status": "200",
"body_bytes_sent": "43",
"request_body": "-",
"content_length": "-",
"http_referer": "http://www.ckl.com/ckl/3459038",
"http_user_agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.122 BIDUBrowser/7.5 Safari/537.36",
"http_x_forwarded_for": "-",
"remote_addr": "117.174.247.112",
"upstream_response_time": "-",
"request_time": "0.000",
"http_x_trace_code": "-"
}
发现，request 字段依然不是json格式，如何修改，nginx测试无法实现（自己无法实现）所以修改了，增加lua脚本，不通过nginx记录日志
而是直接使用lua来记录，lua脚本如下：
#cd /app/local/nginx/lua/
#vim parse.lua
local args = {}
args = ngx.req.get_uri_args()
local v_prev = ""
local sp = "\""
for key,val in pairs(args) do
if key == nil or val == nil then
else
v_prev = v_prev .. sp .. key .. sp .. ":" .. sp .. val .. sp .. ","
end
end
function isnil(value)
if value == nil then
value = "-"
end
return value
end
local logContent = ""
if v_prev ~= nil then
local http_cdn_src_ip = isnil(ngx.var.http_cdn_src_ip)
local time_local = isnil(ngx.var.time_local)
local status = isnil(ngx.var.status)
local body_bytes_sent = isnil(ngx.var.body_bytes_sent)
local request_body = isnil(ngx.var.request_body)
local content_length = isnil(ngx.var.content_length)
local http_referer = isnil(ngx.var.http_referer)
local http_user_agent = isnil(ngx.var.http_user_agent)
local http_x_forwarded_for = isnil(ngx.var.http_x_forwarded_for)
local remote_addr = isnil(ngx.var.remote_addr)
local upstream_response_time = isnil(ngx.var.upstream_response_time)
local request_time = isnil(ngx.var.request_time)
local http_x_trace_code = isnil(ngx.var.http_x_trace_code)
logContent = "{\"http_cdn_src_ip\":" .. sp .. http_cdn_src_ip .. sp .. ",\"time_local\":" .. sp .. time_local .. sp .. ",\"request\":" .. "{" .. string.sub(v_prev,1,#v_prev-1) .. "}" .. ",\"status\":" .. sp .. status .. sp .. ",\"body_bytes_sent\":" .. sp .. body_bytes_sent .. sp .. ",\"request_body\":" .. sp .. request_body .. sp .. ",\"content_length\":" .. sp .. content_length .. sp .. ",\"http_referer\":" .. sp .. http_referer .. sp .. ",\"http_user_agent\":" .. sp .. http_user_agent .. sp .. ",\"http_x_forwarded_for\":" .. sp .. http_x_forwarded_for .. sp .. ",\"remote_addr\":" .. sp .. remote_addr .. sp .. ",\"upstream_response_time\":" .. sp .. upstream_response_time .. sp .. ",\"request_time\":" .. sp .. request_time .. sp .. ",\"http_x_trace_code\":" .. sp .. http_x_trace_code .. sp .. "}"
local file = io.open("/app/data/log/nginx/ckl_access.log","a")
local hc = "\n"
file:write(logContent)
file:write(hc)
file:close()
end
ngx.status = 200
ngx.exit(0)
修改nginx配置：
增加如下：
location ~ /ckl.gif {
set $logContent "";
default_type text/plain;
content_by_lua_file "/app/local/nginx/lua/parse.lua";
}
重启nginx 生效，这个必须重启
/etc/init.d/nginx restart
