jemalloc管理mysql5.7内存

一、安装jemalloc,参考链接

jemalloc编译安装_m0_61237221的博客-CSDN博客https://blog.csdn.net/m0_61237221/article/details/122023459二、配置软链接

ln -s /usr/local/lib/libjemalloc.so.2 /usr/lib64/libjemalloc.so.1

如果不配置会报错&＃xff0c;无法正常启动mysql

三、编辑/etc/my.cnf的[mysqld_safe]

添加malloc-lib&＃61;/usr/lib64/libjemalloc.so.1 如下&＃xff1a;

[mysqld_safe]
malloc-lib&＃61;/usr/lib64/libjemalloc.so.1

 四、重启mysql并验证是否生效

service mysqld restart

查看 jemalloc 是否生效&＃xff1a;

lsof -n |grep jemalloc|grep mysql
