我记得不久前遇到过这个命令，尽管我不记得命令本身。我记得，你运行了命令，它会创建一个临时缓冲区，然后由默认编辑器（vim）编辑，并在关闭缓冲区时执行命令。

例如：

$ <buffer edit command>
~ # Write bash temp script
~ for i in *; do
~     echo $i
~ done
$ file1
$ file2
$ file3
$ ...

有谁知道这个命令是什么？这就像只在 vim 中编写一个 bash 脚本而不保存文件并运行它。

我可以直接通过启动apache httpd，但我不能通过启动它systemctl start httpd。我更喜欢 daemon 方法，这样我就可以让它自动启动。

有人遇到这个问题吗？这是在新的 CentOS7 虚拟机上。

systemctl 启动 http

Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

对默认配置的唯一更改：

/etc/httpd/conf/httpd.conf
IncludeOptional sites-enabled/*.conf

/etc/httpd/sites-enabled/local.com.conf
<VirtualHost *:80>
    ServerName test.local.com
    ServerAlias local.com
    Redirect / https://local.com
</VirtualHost>

<VirtualHost _default_:443>
    ServerName test.local.com
    ServerAlias local.com
    ServerAdmin [email protected]

    DocumentRoot /var/www/local.com/public_html

    ErrorLog /var/www/local.com/error.log
    CustomLog /var/www/local.com/access.log common

    SSLEngine On
    SSLCertificateFile /etc/ssl/certs/www/local.com.crt
    SSLCertificateKeyFile /etc/ssl/certs/www/local.com.key
</VirtualHost>

仅打开端口：

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=443/tcp --permanent
firewall-dmc --reload

这是我从全新的 CentOS7 安装中所做的整个确切过程：

Fresh CentOS 7 installation (VM)

yum upgrade -y

yum search http
yum install -y httpd httpd-devel mod_ssl openssl

systemctl start httpd

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=443/tcp --permanent
firewall-cmd --reload

yum search mariadb
yum install -y mariadb-server

systemctl start mariadb

    mysql -uroot -p
        Login to mysql server works!

yum search php

yum install -y php php-cli php-dba php-devel php-fpm php-mysql php-process php-pspell php-xml

NOTE: I added the following to my desktop's (separate PC) /etc/hosts
    192.168.1.241 test.local.com local.com

    This acts as a DNS record for my site

yum install -y epel-release
yum install -y phpmyadmin

edit /etc/httpd/conf.d/phpMyAdmin.conf
    Add under any line with Require ip 127.0.0.1 with
    Require ip 192.168.1.5

    Add under any line with Allow from 127.0.0.1 with
    Allow from 192.168.1.5

systemctl restart httpd # FAILS
kill pid for httpd
httpd # start httpd directly
    Access https://local.com/phpMyAdmin
    Now have access to phpMyAdmin

    Login with root, 12345
    And have mariadb access!

yum install -y awstats

edit /etc/httpd/conf.d/awstats.conf
     Change Require ip and Allow ip same as phpMyAdmin

cp /etc/awstats/awstats.localhost.localdomain.conf /etc/awstats/awstats.local.com.conf

我的安装有问题吗？

//192.168.1.150/Drew /media/Cloud cifs auto,credentials=/home/drew/.credentials/smb,_netdev,uid=drew,gid=drew,rw 0 0

当我运行sudo mount -a驱动器已安装时，没有问题。但是，系统启动时驱动器不会自动挂载？
