tcMalloc优化nginx 

记住：nginx一定要先启动

1>下载安装libunwind:

#wget  http://download.savannah.gnu.org/releases/libunwind/libunwind-0.99.tar.gz

wget  http://download.savannah.gnu.org/releases/libunwind/libunwind-0.99-alpha.tar.gz

tar -zxvf libunwind-0.99-alpha.tar.gz

cd libunwind-0.99-alpha

CFLAGS=-fPIC  ./configure

make CFLAGS=-fPIC

make CFLAGS=-fPIC install

 

2>下载安装Google-perftools

wget  http://soft.7dot.com/soft/google-perftools-1.8.tar.gz

tar  -zxvf  google-perftools-1.8.tar.gz

cd google-perftools-1.8

./configure

make  &&  make install

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

ldconfig

 

3>又一次编译nginx(使nginx支持Google-perftools)

cd nginx-1.2.8

./configure  --with-google_perftools_module  --with-http_stub_status_module 

 

 

#./configure \

#> --with-google_perftools_module  --with-http_stub_status_module    #--prefix=/usr/local/nginx

 

 

make 

make install

 

4> 为google-perftools 加入线程文件夹

mkdir /tmp/tcmalloc

chmod 0777 /temp/tcmalloc 

 

5> 改动nginx主配置文件

cd  /usr/local/nginx/conf

改动nginx.conf 在pid这行加入以下代码

#pid logs/nginx.pid

#google_perftools_profiles /tmp/tcmalloc/

google_perftools_profiles /tmp/tcmalloc

 

 

检查nginx.conf配置是否正确

/usr/local/nginx/sbin/nginx  -t  -c   /usr/local/nginx/conf/nginx.conf

#/usr/local/nginx/sbin/nginx  -t  -c  /usr/local/nginx/sbin/conf/nginx.conf

 

重新启动nginx

/usr/local/nginx/sbin/nginx -s reload

#kill -HUP  cat /usr/local/nginx/logs/nginx.pid

ps ax  | grep nginx | grep -v grep   | awk  '{print $1}' | xargs  kill -9 

6>  验证

lsof -n | grep tcmalloc
