老服务器系统用的centos6.5，后来新买了几台服务器，centos7，跑nginx+php,遇到的问题总结如下：
1、服务器初始化：yum -y install lrzsz make cmake gcc gcc-c++ gcc-g77 autoconf automake nc curl-devel libpng-devel libjpeg-devel libuuid libuuid-devel zlib* fiex* libxml* ncurses-devel bison libmcrypt* libtool-ltdl-devel* libiconv mhash mcrypt pcre-devel openssl openssl-devel gperf libevent libevent-devel bzip2 bzip2-devel bzip2-libs subversion telnet nc.x86_64 python-devel python-setuptools

2、从老机器scp编译好的nginx+php+supervisord，启动服务时，遇到一堆报错。
supervisord：pkg_resources.DistributionNotFound: supervisor==3.1.3
解决方法为重新安装supervisord： easy_install supervisor
nginx：/usr/local/app/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory
解决方法：ldd $(which /usr/local/app/nginx/sbin/nginx) 查看缺少的库文件，找到后做一个软连接：ln -s /lib64/libpcre.so.1.2.0 /lib64/libpcre.so.0
php：/usr/local/app/php/sbin/php-fpm: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory
解决方法：ldd $(which /usr/local/app/php/sbin/php-fpm) 查看缺少的库文件得到结果：libpng12.so.0 => not found 执行yum install libpng12 -y
