需求

magento2 在运行的时候会不断在项目中var/log中记录日志,时间久后就会产生巨大的log日志,所以有必要每天切割日志保存,利于日志分析和减少磁盘开销。

方法 (仅对于linux)

1.首先确定当前的项目名称(magento2)和项目路径(/var/www/magento2),项目执行用户www

2.sudo vim /etc/logrotate.d/magento2
3.拷贝以下内容到/etc/logrotate.d/magento2

# runs, older logs have already been rotated, so it's safe to
# rotate an unexpected log.1 file into log.2.gz. Sometimes the
# argument already has a .1 suffix, so strip it.

curl: (60) SSL certificate problem: certificate has expired

More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and how to fix it, please visit the web page mentioned above.

问题原因

由于服务器curl证书问题导致无法正确访问https站点

在deepin linux中安装nvidia官方驱动的方法

首先,到nvdia官网下载对应显卡的linux驱动
https://www.nvidia.com/Download/index.aspx?lang=en-us
一般对应的下载文件会在~/Downloads下,将它重新命令nvidia.sh便于后面引用。

接下来请按照以下步骤执行。

  1. 卸载nvidia开源驱动和闭源驱动

    1
    sudo apt autoremove nvidia-*
  2. 禁止nouveau驱动

    1
    sudo dedit /etc/modprobe.d/blacklist.conf

    执行以上代码打开blacklist.conf文件后复制以下内容并保存关闭

    1
    2
    3
    4
    5
    blacklist nouveau
    blacklist lbm-nouveau
    options nouveau modeset=0
    alias nouveau off
    alias lbm-nouveau off
  3. blacklist.conf添加执行权限

    1
    sudo chmod +x /etc/modprobe.d/blacklist.conf

    blacklist nouveau是禁用nouveau第三方驱动,之后不需要改回来,由于nouveau是构建在内核中的,所以要执行下面代码集成到内核中

    1
    sudo update-initramfs -u

    好了,到现在为止,前期工作已经完成。

  4. 重启
    可以运行以下命令

    1
    reboot
  5. 重启后查看nouveau有没有运行,没有输出则代表禁用生效

    1
    lsmod | grep nouveau
  6. 同时按住ctrl+alt+F2键,进入tty2。输入当前用户名点击enter然后再输入密码点击enter进入。

  7. 导航到Downloads目录,为nvidia.sh添加执行权限。

    1
    cd ~/Downloads && chmod +x nvidia.sh
  8. 关闭图形界面

    1
    sudo systemctl stop lightdm
  9. 安装显卡驱动

    1
    sudo sh nvidia.sh

    请注意接下来的步骤,一定要完成相同,否则将造成无法登陆图形界面

    注意英文字母中出现大写的“DKMS”选择Yes

    注意英文中出现“32-bit”选择Yes

    注意英文中出现“nvidia-xconfig”一定要选择No

  10. 输入reboot重启电脑,安装完成

打包后安装出现双图标

解决办法

desktop中添加StartupWMClass=xxx
xxx通过终端中执行xprop WM_CLASS点击应用程序获取。
