昨天把ansible-tower安装在这机器上，然后把原来的nginx霸占了，逼迫把zabbix的web换上了apache，源码安装上apache和重新编译php后，就出现这个php错误提示。

附上关于zabbix的apache和php的源码指定的模块

./configure --prefix=/usr/local/php  --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php/etc  --with-pdo-mysql=/usr/local/mysql  --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir  --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl  --with-mcrypt --enable-soap  --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exifwget https://mirrors.cnnic.cn/apache/httpd/httpd-2.4.29.tar.gz  wget https://mirrors.cnnic.cn/apache/apr/apr-1.6.3.tar.gz  wget https://mirrors.cnnic.cn/apache/apr/apr-util-1.6.1.tar.gz    apache源码编译  ./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util  --enable-so --enable-mods-shared=most  ★ 在zabbix页面上显示A session had already been started - ignoring session_start()这个提示，把session.auto_start = 1改为0即可  编辑httpd.conf文件添加如下代码LoadModule php7_module modules/libphp7.soAddType application/x-httpd-php .phpDirectoryIndex index.php index.htm index.html
