我已经安装了PHP 7、mysql5.7、Apache2.2、CentOS6。
我正在安装CodeIgniter3.0.6。
当我使用数据库连接时,出现错误并表示
A PHP Error was encountered
Severity: Core Warning
Message: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/php_mysqli.so' - /usr/lib64/php/modules/php_mysqli.so: cannot open shared object file: No such file or directory
Filename: Unknown
Line Number: 0
当然,"/usr/lib64/php/modules/php_mysqli.so"中没有文件,但我不知道如何安装mysqli.so.
我试过
yum install php-mysql
但是

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
但没用。
当我执行yum install php7.0-mysql
或yum install php70w-mysql
命令时,

No package php7.0-mysql available.
Error: Nothing to do
我根本不知道该怎么办。
对于PHP7,在Cent/RHEL:
yum install php70w-mysql
如果您使用Remi存储库
yum install php70-php-mysqlnd
适用于Ubuntu:
apt-get install php7.0-mysql
请注意,mysql扩展已被弃用,并且在PHP7中已不存在。
php-mysqlnd包仅提供mysqli和pdo_mysql扩展。
php-pecl-mysql也可用,从git快照构建,为兼容遗留应用程序而提供,但不受支持。
来自最初的问题:
已安装:php-common-7.0.4-1.el6.remi.x8_64(@remi-hp70)
您已经从remi-hp70安装了php 7.0.4,但未启用存储库。您需要启用它,这样百胜就会找到与安装版本匹配的正确软件包。
根据配置向导说明:
yum install yum-utils
yum-config-manager --enable remi-php70
yum install php-mysqlnd
注意:安装"foo"扩展的正确命令是yum-install-php-foo,因此"yum-install-pahp-mysql"将安装提供mysql扩展的包(so php-pecl-mysql),"yum-install-php-mysqli"将安装提供mysql的包(所以php-mysqlnd)。
