問題列表：
- mail() 函數(shù)使用吕漂；
- 配置 php.ini;
- mail()函數(shù)報(bào)錯(cuò)的解決過程迟几；
使用函數(shù)：
mail(‘example@qq.com', 'There is a new connect', $connection->getRemoteIp());
配置文件 php.ini
$ php -i

mail() 函數(shù)報(bào)錯(cuò)
錯(cuò)誤詳情 - sendmail: fatal: parameter inet_interfaces: no local interface found for ::1
解決報(bào)錯(cuò)步驟：
查看centos中的postfix日志
$ more /var/log/maillog
postfix: fatal: parameter inet_interfaces: no local interface found for ::1
$ vi /etc/postfix/main.cf
發(fā)現(xiàn)配置為：
inet_interfaces = localhost
inet_protocols = all
改成：
inet_interfaces = all
inet_protocols = all
重新啟動(dòng)
service postfix start
執(zhí)行重啟，出現(xiàn)報(bào)錯(cuò)
$sudo service postfix start
Redirecting to /bin/systemctl start postfix.service
Job for postfix.service failed because the control process exited with error code. See "systemctl status postfix.service" and "journalctl -xe" for details.
[james@VM_123_128_centos camerawk]$ systemctl status postfix.service

再次打開 /etc/postfix/main.cf 文件.
有兩個(gè) inet_interface匕垫，一個(gè) inet_interfaces = all（這是我打開的）雏门，一個(gè)是 inet_inter_faces = localhost。
注釋 inet_interfaces = localhost 這個(gè)鼎姐，再次重啟就ok了。
inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost
#inet_interfaces = localhost
