1.安裝LuaJIT-2.0.4

鏈接：

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.修改環(huán)境變量

vim?/etc/profile

export?LUAJIT_LIB=/usr/local/luajit/lib

export?LUAJIT_INC=/usr/local/luajit/include/luajit-2.0

source?/etc/profile

3.下載nginx lua模塊

ngx_devel_kit 鏈接：https://github.com/simpl/ngx_devel_kit/tags

lua-nginx-module 鏈接：https://github.com/openresty/lua-nginx-module/tags

4.編譯nginx 增加支持模塊

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.編譯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.備份原有的程序及增加鏈接

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.查看模塊

#?/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 修改為json格式

修改很簡單，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":?"-"

}

發(fā)現(xiàn)，request 字段依然不是json格式，如何修改，nginx測試無法實(shí)現(xiàn)(自己無法實(shí)現(xiàn))所以修改了，增加lua腳本，不通過nginx記錄日志

而是直接使用lua來記錄，lua腳本如下：

#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";

}

重啟nginx 生效，這個(gè)必須重啟

/etc/init.d/nginx?restart

查看新的json

{

"http_cdn_src_ip":?"-",

"time_local":?"01/Aug/2016:02:01:02?+0800",

"request":?{

"t":?"1469988090580",

"category":?"player",

"action":?"bufferEmpty",

"platform":?"pc",

"loc":?"/v/2955653"

},

"status":?"000",

"body_bytes_sent":?"0",

"request_body":?"-",

"content_length":?"-",

"http_referer":?"http://www.ckl.com/v/2955653",

"http_user_agent":?"Mozilla/5.0?(Windows?NT?6.1;?WOW64)?AppleWebKit/537.36?(KHTML,?like?Gecko)?Chrome/45.0.2454.101?Safari/537.36",

"http_x_forwarded_for":?"-",

"remote_addr":?"221.226.105.101",

"upstream_response_time":?"-",

"request_time":?"0.000",

"http_x_trace_code":?"-"

}
