注意，nginx一定要先启动
1，下载安装libunwind:
复制代码 代码示例:
#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
复制代码 代码示例:
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)
复制代码 代码示例:
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
复制代码 代码示例:
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
6，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
7，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 |
linuxjishu/13830.html target=_blank class=infotextkey>awk '{print $1}' |
xargs kill -9
8，验证 tcmalloc是否安装成功
lsof -n | grep tcmalloc
以上通过实例介绍了使用tcMalloc配置优化nginx性能的方法，希望对大家有所帮助。
