CentOS Upgrade Jemalloc Optimize MySQL Optimize Nginx

This tutorial has been practiced on this blog linpx.com on March 11, 2016, including upgrading or installing Jemalloc, optimizing MySQL and Nginx.

So now:

Upgrade or install Jemalloc

 wget  http://www.canonware.com/download/jemalloc/jemalloc-4.1.0.tar.bz2 tar xjf jemalloc-4.1.0.tar.bz2 cd jemalloc-4.1.0 ./configure make && make install echo '/usr/local/lib' > /etc/ld.so.conf.d/local.conf ldconfig

Use jemalloc to optimize MySQL

Method 1:

MySQL/MaridDB compilation method, add the following parameters when cmake is precompiled

 -DCMAKE_EXE_LINKER_FLAGS="-ljemalloc" -DWITH_SAFEMALLOC=OFF

Method 2:

Use the following code to automatically modify the mysqld_safe file

 sed -i 's@executing  mysqld_safe@executing  mysqld_safe\nexport LD_PRELOAD=/usr/local/lib/libjemalloc.so@' /usr/local/mysql/bin/mysqld_safe

Restart MYSQL

CentOS 6.x：

 service mysqld restart

CentOS 7.x：

 systemctl restart mysqld

Optimize Nginx with jemalloc

Upgrade Nginx to 1.9.12

 cd /usr/src wget  http://nginx.org/download/nginx-1.9.12.tar.gz tar -xzvf nginx-1.9.12.tar.gz

Check the configuration arguments of your Nginx. The next step of installation and compilation requires

 nginx -V

Copy the content of configure arguments in/ After configure, bring the content you copied, and then don't forget to bring it --with-ld-opt="-ljemalloc"

 cd nginx-1.9.12 make clean ./configure --prefix=/usr/local/nginx --user=www --group=www --with-openssl=/usr/src/openssl-1.0.2g --with-http_stub_status_module --with-http_v2_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-ld-opt="-ljemalloc" make && make install

Verify whether jemalloc optimized Nginx works

 lsof -n | grep jemalloc
