一、安装libunwind
wget http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gz
本地下载:https://files.cnblogs.com/files/hacker1394/libunwind-1.1.tar.gz
tar zxvf libunwind-1.1.tar.gz
CFLAGS=-fPIC ./configure --enable-shared
make CFLAGS=-fPIC
make CFLAGS=-fPIC install
二、google模块
下载地址:https://code.google.com/p/gperftools/ (需FQ)
wget https://googledrive.com/host/0B6NtGsLhIcf7MWxMMF9JdTN3UVk/gperftools-2.2.1.tar.gz
本地下载:https://files.cnblogs.com/files/hacker1394/gperftools-2.4.tar.gz
tar zxvf gperftools-2.2.1.tar.gz
./configure --enable-shared --enable-frame-pointers
make
make install
三、更新,使动态链接库能够被系统共享
echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf
ldconfig
四、建立目录
mkdir -p /tmp/tcmalloc/
chmod 777 /tmp/tcmalloc/
五、一键脚本
下载地址:https://files.cnblogs.com/files/hacker1394/setup.sh
使用方法:
mkdir -p /root/setup/Nginx
下载的三个文件放至Nginx文件夹
chmod +x /root/setup/Nginx/setup.sh
./setup.sh
六、nginx 加载google_perftools_module
例:./configure --user=website --group=website --prefix=/usr/local/nginx/ --with-google_perftools_module
修改nginx.conf
在pid下添加一行
google_perftools_profiles /tmp/tcmalloc;
service nginx restart (重启nginx)
验证:lsof -n | grep tcmalloc
七、MySQL
修改MySQL启动脚本(my.cnf)
vim /usr/local/mysql/bin/mysqld_safe
在 #executing mysqld_safe 下增加如下:
export LD_PRELOAD=/usr/local/lib/libtcmalloc.so
service mysqld restart (重启mysql)
验证: lsof -n | grep tcmalloc
