Tutorial of full version that optimizes nginx's performance at high concurrency using google perftools

Note: this tutorial is for Linux only.

Here's how to install google-perftools and configure Nginx and MySQL to support google-perftools.

First, how to optimize Nginx:

1, first download and install google-perftools:

Note that if you have a 64-bit system :

So what you need to do :
1) install libunwind first or 2) add -- enable-frame-pointers.

at configure

So first, how to install libunwind:

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

Go here and install libunwind.

If we're going to add -- enable-frame-pointers, forget it, let's go down.

Download and install google-perftools :

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 configuring :

./configure --prefix=/usr --enable-frame-pointers

If it's a 32-bit system, you don't need to add -- enable-frame-pointers. If it's a 64-bit system, and you didn't install libunwind before, you must add this :-- enable-frame-pointers

Compile and install :

make
make install

Go here and install google-perftools completed but not in effect, next you need to make es1064en-perftools in effect :

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

Note that the double quotes here are in English.

Go here and install google-perftools.

To make Nginx support google-perftools, you need to add -- with-google_perftools_module to recompile Nginx. If you don't know how to install Nginx, you can see the Nginx installation tutorial here

For example:

./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

To add the Nginx quick restart script, download.
from wpadm.com Go here and install Nginx.

Next, add the threads directory for google-perftools :

mkdir /tmp/tcmalloc
chmod 0777 /tmp/tcmalloc

Modify/usr/local/nginx/conf/ncing conf
Add
below the pid row

#pid   logs/nginx.pid;
google_perftools_profiles /tmp/tcmalloc;

Restart nginx:

service nginx restart

Verify that it is running :

[root@localhost ~]# lsof -n | grep tcmalloc

My server has 8 cores, so I have 8 Nginx threads open, and each thread will have a similar row of records.
As a result, the optimized installation of google-perftools under nginx has been completed, for friends' reference.
