Apache 环境变量问题

Question

我正在尝试从 Debian 7 上的 Apache 2.2 迁移到 CentOS 7 上的 Apache 2.4。据我所知，在 Debian 7 上有一个名为 "envvars" 的文件，如下所示，它必须存在于 CentOS 7 上。

# envvars - default environment variables for apache2ctl

# this won't be correct after changing uid
unset HOME

# for supporting multiple apache2 instances
if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
    SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
    SUFFIX=
fi

# Since there is no sane way to get the parsed apache2 config in scripts, some
# settings are defined via environment variables and then used in apache2ctl,
# /etc/init.d/apache2, /etc/logrotate.d/apache2, etc.
export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
export APACHE_PID_FILE=/var/run/apache2$SUFFIX.pid
export APACHE_RUN_DIR=/var/run/apache2$SUFFIX
export APACHE_LOCK_DIR=/var/lock/apache2$SUFFIX
# Only /var/log/apache2 is handled by /etc/logrotate.d/apache2.
export APACHE_LOG_DIR=/var/log/apache2$SUFFIX

我在 httpd.conf 所在的 conf 下创建了相同的文件，但它没有工作，并将内容添加到 /etc/sysconfig/httpd，但错误停止了运行 apache 服务器，如下所示。

我尝试了 source envvars 来测试 environemts 是否有效，但它没有。有什么方法可以添加环境变量，以便它在我启动 Apache 时应用？

谢谢！

Answer 1

在 httpd.conf 中声明您的变量：定义（最好在第一行）

Define APACHE_RUN_USER Apache

您以后可以像这样使用这个变量：

User ${APACHE_RUN_USER}
