Reboot Service:

# /program/haproxy/sbin/haproxy -f /program/haproxy/haproxy.cfg -st `cat /program/haproxy/logs/haproxy.pid`

Stop Service:

# killall haproxy

Download address

http://nginx.org/download/nginx-1.5.6.tar.gz

Install pcre first.
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.33.tar.gz
Then, configure, make, make install.

At the end, make a soft link.

ln -s /usr/local/lib/libpcre.so.1 /usr/lib/

Starting install nginx, compile the parameters as follows:
./configure –prefix=/program/nginx –user=root –group=root –with-pcre –with-select_module –with-poll_module –with-http_stub_status_module –with-http_ssl_module –with-http_realip_module –with-http_gzip_static_module

HAProxy：

nginx：

Conclusion:
If you simply reverse connection, both have the same efficiency. HAProxy back end detection works well, for handling long connection is also very good. Can load mysql and other servers. nginx has a more powerful modules, such as cache, uwsgi together with other functions, nginx on a lot of convenience. WEB services uses nginx, others need loads can use HAProxy.[/vc_column_text][/vc_tab][/vc_tour][/vc_column][/vc_row]
