Nginx

Docroot is: /usr/local/var/www

 

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that

nginx can run without sudo.

 

nginx will load all files in /usr/local/etc/nginx/servers/.

 

To restart nginx after an upgrade:

  brew services restart nginx

Or, if you don't want/need a background service you can just run:

  /usr/local/opt/nginx/bin/nginx -g daemon off;

使用文档：http://www.festvox.org/flite/doc/flite_7.html#C-example

示例代码：

 

#include "flite.h"
cst_voice *register_cmu_us_kal(const char *voxdir); // 注意这一行和官方文档不同，官方文档的会报错。

int main(int argc, char **argv)
{
    cst_voice *v;

    -o-filter: grayscale(100%) !important;
    filter: grayscale(100%) !important;

Odilia is a new screen reader for the Linux desktop. It’s written in Rust, for maximum performance and stability.

命令行下ulimit -aS可查看最大打开文件数。

ulimit -n 65535可设置最大打开文件数。

下面步骤可调大Apache里php进程的最大打开文件数（默认可能是1024）：

修改/usr/lib/systemd/system/httpd.service里的LimitNOFILE=65535，

sudo systemctl daemon-reload

sudo service httpd restart

安装vsftpd的命令如下：

sudo apt install vsftpd

默认配置下，可以登录Ubuntu系统内用户 。

如果系统允许匿名下载，可以编辑/etc/vsftpd.conf修改如下配置：

 

anonymous_enable=YES

anon_root=/var/ftp

手动创建匿名用户根目录：

sudo mkdir /var/ftp

去掉FTP匿名用户根目录写权限（不然不允许登录）：

sudo chmod a-w /var/ftp

放一个测试文件：

sudo touch /var/ftp/test

重启服务：

sudo service vsftpd restart
