CentOS 5.5下安装完成后主要是遇到了下面错误，记录下来供大家参考： sh: -t: command not found

我的系统是通过网络最小化安装的，所以有很多命令和小工具以及一些服务都没有安装。

今天抽空安装了一下Sendmail： 1. 查找需要安装包:

yum search sendmail

Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * addons: centos.mirror.cdnetworks.com * base: centos.mirror.cdnetworks.com * extras: centos.mirror.cdnetworks.com * updates: centos.mirror.cdnetworks.com ======================================================== Matched: sendmail ========================================================= exim.x86_64 : The exim mail transfer agent php-pear-Mail.noarch : Class that provides multiple interfaces for sending emails sendmail.x86_64 : A widely used Mail Transport Agent (MTA). sendmail-cf.x86_64 : The files needed to reconfigure Sendmail. sendmail-devel.i386 : Extra development include files and development files. sendmail-devel.x86_64 : Extra development include files and development files. sendmail-doc.x86_64 : Documentation about the Sendmail Mail Transport Agent program. spamassassin.x86_64 : Spam filter for email which can be invoked from mail delivery agents. sysklogd.x86_64 : System logging and kernel message trapping daemons.

1. 我选择性进行了安装：

yum install sendmail sendmail-devel sendmail-cf sendmail-doc mailx

mailx 方便命令行发邮件

1. 安装完成，下面开始测试 3.1 命令行测试：

# echo "abc" |mail -s "Submect test" web@www.linuxidc.com``

检查邮件，发送成功。 如果没有收到可以查看/var/log/maillog中数据内容。 3.2 写PHP进行测试 将下面代码保存为mailtest.php：

$message = 'test mail for www.linuxidc.com'; mail('web@www.linuxidc.com', 'My Subject', $message);

然后执行进行测试：

php mailtest.php

提示错误：

sh: -t: command not found

解决办法配置php.ini, 主要原因是sendmail_path找不到sendmail：

vi /usr/local/php/lib/php.ini

SMTP            = localhost smtp_port      = 25 sendmail_path = '/usr/sbin/sendmail.sendmail -t -i' mail.add_x_header = On mail.log                =/tmp/mail.log
