WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

解决方法:
在
etc/sysctl.conf
文件中
添加
net.core.somaxconn= 1024

然后执行sysctl -p 就可以永久消除这个warning

Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

解决方法:
# yum install m4
# yum install autoconf
