google server ubuntu use

step 1. 因为是64位的系统,所以先要安装libunwind,32位系统可以忽略此步 wget http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gztar zxvf libunwind-1.1.tar.gzcd libunwind-1.1/CFLAGS=-fPIC ./configure --enable-sharedmake CF

step 1. 因为是64位的系统,所以先要安装libunwind,32位系统可以忽略此步

wget http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gz
tar zxvf libunwind-1.1.tar.gz
cd libunwind-1.1/
CFLAGS=-fPIC ./configure --enable-shared
make CFLAGS=-fPIC
make CFLAGS=-fPIC install
Copy after login

step 2.安装Google Performance Tools

wget https://gperftools.googlecode.com/files/gperftools-2.1.tar.gz
tar zxvf gperftools-2.1.tar.gz
cd gperftools-2.1/
./configure
make -j8
make install
echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf
/sbin/ldconfig
Copy after login

step 3. 修改MySQL启动脚本(根据你的MySQL安装位置而定):

vi /usr/local/mysql/bin/mysqld_safe
Copy after login

在# executing mysqld_safe的下一行,加上:

export LD_PRELOAD=/usr/local/lib/libtcmalloc.so
Copy after login

保存后退出,然后重启MySQL服务器。

step 4. 使用lsof命令查看tcmalloc是否起效:

lsof -n|grep tcmalloc
Copy after login

如果发现以下信息,就证明配置成功了。

mysqld    12278      mysql  mem       REG              202,1    2241773    1186797 /usr/local/lib/libtcmalloc.so.4.1.2
Copy after login
