【已解答】安装包找不到libtocmalloc

[root@VM-0-5-centos ~]# yum install libtocmalloc* -y
Loaded plugins: fastestmirror, langpacks
Repository epel is listed more than once in the configuration
Loading mirror speeds from cached hostfile
No package libtocmalloc* available.
Error: Nothing to do

没有这个包，说明你yum镜像源是没有的，另外你要确保包名称正确。
