CentOS 7 安装PHP7.3.2 - 编译安装（并安装redis扩展）
1 安装扩展包并更新系统内核
yum install epel-release -y
yum update
2 YUM安装PHP依赖组件（包含Nginx依赖）：
yum -y install php-mcrypt libmcrypt-devel libxml2 libxml2-devel curl-devel libjpeg-devel libpng-devel freetype-devel libmcrypt-devel libxslt libxslt-devel cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel cyrus-sasl-lib m4 autoconf gcc gcc-c++ openssl openssl-devel pcre pcre-devel zlib zlib-devel wget net-tools zip
3 编译安装配置PHP
3.1 下载应用软件包

/usr/local/lib
/usr/lib
/usr/lib64'>>/etc/ld.so.conf
更新配置
ldconfig -v
错误2
