我正在尝试设置 mysqlnd_ms 以便它达到在从数据库上读取并在主数据库上写入的目的。但是,重新启动 httpd 时出现此错误。
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mysqlnd_ms.so' - /usr/lib64/php/modules/mysqlnd_ms.so: undefined symbol: mysqlnd_global_stats in Unknown on line 0
我正在运行一个 Amazon EC2 x64 AMI 实例并在一个新实例上运行以下命令:
sudo yum update
sudo yum install -y gcc make gcc-c++
sudo yum install -y httpd24 php54
sudo yum install -y php54-devel php54-mysqlnd php54-mbstring
sudo pecl install mysqlnd_ms
php -m | grep mysql
我的 php.ini 添加了以下内容:
mysqlnd_ms.enable=1
mysqlnd_ms.force_config_usage=1
mysqlnd_ms.config_file=/etc/mysqlnd_ms.ini
extension=mysqlnd_ms.so
mysqlnd_ms.ini 文件有这个:
{
"appname": {
"master": {
"master_0": {
"host": "1.2.3.4",
"db": "dbname",
"user": "dbuser",
"password": "dbpswd",
"socket" : "\/var\/lib\/mysql\/mysql.sock"
}
},
"slave": {
"slave_0": {
"host": "12.22.32.42",
"db": "dbname",
"user": "dbuser",
"password": "dbpswd",
"socket" : "\/var\/lib\/mysql\/mysql.sock"
}
}
}
}
要连接,我会:
$mysqli = new mysqli("appname", "dbuser", "dbpswd", "schema");
执行上述操作会引发以下错误:
ERROR: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
mysqli、mysql和pdo都在服务器上启用。
如果我们直接将其更改为主机名,它可以工作:
$mysqli = new mysqli("1.2.3.4", "dbuser", "dbpswd", "schema");
如何让 mysqlnd_ms 正常运行?
