Nginx copy traffic

Use Ngnix to copy online traffic to the test machine (one http request is regarded as one piece of traffic)
Development environment: CentOS 6.4
nginx installation directory: /usr/local/nginx-1.4.2
Download directory of each module installation package: /data/nginxinstall
1. Install pcre
#yum -y install pcre pcre-devel
2. Install zlib
yum -y install zlib zlib-devel
3. Install LuaJIT
# cd /data/nginxinstall
# wget http: //luajit.org/download/LuaJIT-2.0.2.tar.gz
# tar -xzvf LuaJIT-2.0.2.tar.gz
# cd LuaJIT-2.0.2
# make
lib and include are placed directly /usr/local/lib and usr/local/include
Configure environment variables
export LUAJIT_LIB=/usr/local/lib
export LUAJIT_INC=/usr/local/include/luajit-2.0
export LD_LIBRARY_PATH=/usr/local/lib :$LD_LIBRARY_PATH
4. Download and prepare httpLuaModule
# cd /data/nginxinstall
# wget https://github.com/chaoslawful/lua-nginx-module/archive/v0.8.6.tar.gz
# tar -xzvf v0 .8.6
5. Start installing Nginx below (trying to use nginx1.10.0 and encountering compilation errors):
# cd /data/nginxinstall/
# wget http://nginx.org/download/nginx-1.4.2.tar .gz
# tar -xzvf nginx-1.4.2.tar.gz
# cd nginx-1.4.2
# ./configure --prefix=/usr/local/nginx-1.4.2 --add-module=. ./lua-nginx-module-0.8.6
# make -j2
# make install
6. Edit the nginx/conf/nginx.conf file (this file is in json format and can be seen as a tree):
In Add under http nodes:
Upstream online {
server 10.10.12.7:80 ;
}
upstream test {
server 10.10.10.103:80 ;
}
location ~* ^/antispam { Bleak client_body_buffer_size 2m;
Set $svr "on"; ^/s1(.*)$ $1 break;
proxy_pass http://s1; -- Reverse proxy, jump to upstream online
}
location ~* ^/test {
log_subrequest on;
rewrite ^/test(.*)$ $1 break;
proxy_pass http: //test; -- Reverse proxy, jump to upstream test
}
7. Edit nginx/copy_flow.lua file:
local online, test, action
action = ngx.var.request_method
if action == "POST " then
ngx.req.read_body() -- Be sure to read the body before parsing the body parameters
local arg = ngx.req.get_post_args() -- post requires parameters to be passed
arry = {method = ngx.HTTP_POST, body = ngx.var.request_body, args=arg}
else
arry = {method = ngx.HTTP_GET}
end
if ngx.var.svr == "on" then
online, test = ngx.location.capture_multi {
{ "/online" .. ngx.var.request_uri, arry},
{ "/test" .. ngx.var.request_uri, arry},
}
else
online = ngx.location.capture_multi {
{ "/ online" .. ngx.var.request_uri, arry}
}
end
if online.status == ngx.HTTP_OK then -- only return the results of the online server
ngx.say(online.body)
else
ngx.status = ngx.HTTP_NOT_FOUND



end



8. There is Chinese in the POST parameters, encoding problem:

Nginx configuration UTF8: Configure charset utf-8 under the server node; Format:

The above has introduced Nginx copy traffic, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
