You can either disable the module by using--without-http-cache option, or install the OpenSSL library into the system,or build the OpenSSL library statically from the source with nginx by using--with-http_ssl_module --with-openssl=<path> options. 解决办法：yum -y install openssl openssl-devel3 环境变量：方法一：直接运行命令export PATH=$PATH:/usr/local/webserver/php/bin 和 export PATH=$PATH:/usr/local/webserver/mysql/bin使用这种方法，只会对当前会话有效，也就是说每当登出或注销系统以后，PATH 设置就会失效，只是临时生效。方法二：执行vi ~/.bash_profile修改文件中PATH一行，将/usr/local/webserver/php/bin 和 /usr/local/webserver/mysql/bin 加入到PATH=$PATH:$HOME/bin一行之后这种方法只对当前登录用户生效方法三：修改/etc/profile文件使其永久性生效，并对所有系统用户生效，在文件末尾加上如下两行代码PATH=$PATH:/usr/local/webserver/php/bin:/usr/local/webserver/mysql/binexport PATH最后：执行 命令source /etc/profile或 执行点命令 ./profile使其修改生效，执行完可通过echo $PATH命令查看是否添加成功。
