Use Google-perftools to optimize nginx performance during high concurrency (full version) _nginx

Note: This tutorial is only available for Linux.

Here is a description of Google-perftools installation, and configure Nginx and MySQL support Google-perftools.

First, describe how to optimize nginx:

1, first download and install Google-perftools:

Note that if the 64-bit system is:

Then you need to do:
1 Install Libunwind or 2 first, add--enable-frame-pointers at configure.

So first, let's talk about how to install Libunwind:

Copy Code code as follows:

wget http://download.savannah.gnu.org/releases/libunwind/libunwind-0.99.tar.gz
Tar zxvf libunwind-0.99.tar.gz
CD libunwind-0.99/
Cflags=-fpic./configure--prefix=/usr
Make Cflags=-fpic
Make Cflags=-fpic Install

Install Libunwind here to complete.

If you are using the way to add--enable-frame-pointers, let's go down.

Download and install Google-perftools:

Copy Code code as follows:

wget http://google-perftools.googlecode.com/files/google-perftools-1.7.tar.gz
Tar xzvf google-perftools-1.7.tar.gz
CD google-perftools-1.7

Then start the configuration:

Copy Code code as follows:

./configure--PREFIX=/USR--enable-frame-pointers

Note This step here, if it is a 32-bit system, you can not add--enable-frame-pointers, if it is a 64-bit system, and you did not install Libunwind before, then you must add this:--enable-frame-pointers

Compile and install:

Copy Code code as follows:

Make
Make install

The installation google-perftools is complete but not effective, and the next step is to make the Google-perftools effective:

Copy Code code as follows:

echo "/usr/local/lib" >/etc/ld.so.conf.d/usr_local_lib.conf
/sbin/ldconfig

Note that the double quotes here are in English.

Install Google-perftools here to complete.

In order for Nginx to support google-perftools, you need to add--with-google_perftools_module recompile nginx, and if you don't know how to install Nginx, you can view the Nginx installation tutorials from here.

For example:

Copy Code code as follows:

./configure--user=www--group=www--prefix=/usr/local/nginx \
--with-http_stub_status_module \
--with-http_ssl_module--with-openssl= \
--with-http_addition_module \
--with-zlib= \
--with-google_perftools_module
Make
Make install

Add Nginx Quick Restart script, download from wpadm.com.
Install Nginx here to complete.

Next, add the thread directory for Google-perftools:

Copy Code code as follows:

Mkdir/tmp/tcmalloc
chmod 0777/tmp/tcmalloc

Modify/usr/local/nginx/conf/ncing.conf
Add below the PID line

Copy Code code as follows:

#pid Logs/nginx.pid;
Google_perftools_profiles/tmp/tcmalloc;

Reboot Nginx:

Copy Code code as follows:

Service Nginx Restart

Verify that you are running:

Copy Code code as follows:

[Root@localhost ~]# Lsof-n | grep tcmalloc

My server has 8 cores, so 8 nginx threads are turned on, and each thread has a row of similar records.
To some, nginx under the Google-perftools optimization installation completed, for friends to learn reference.
