tcMalloc 配置和优化 nginx 高性能

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>重新编译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 添加线程目录
mkdir /tmp/tcmalloc
chmod 0777 /temp/tcmalloc

5> 修改nginx主配置文件
cd /usr/local/nginx/conf
修改nginx.conf 在pid这行添加下面代码
#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

重启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
