1 按照官网安装手册安装WSL UBUNTU

在windows10 上安装linux系统。具体参考官方文档。
https://docs.microsoft.com/en-us/windows/wsl

2 中文支持

启动WSL安装中文包

apt-get update
apt-get install language-pack-zh-hans
update-locale LANG=zh_CN.UTF-8

重启

3 window10 命令行乱码

按下WIN+R快捷键,在运行的窗口中输入:control,打开控制面板;

选择区域–>管理–>非Unicode程序的语言–>更改系统区域设置:中文(简体,中国)

重启电脑,dos中文操作显示,中文输入可以正常使用。

With mysqldump it is not possible by the parameters to exclude individual databases. However, the database can be easily queried from the information_schema and this makes an exclude.

多个mp3文件合并成一个mp3文件

一种方法是连接到一起

1
ffmpeg64.exe -i "concat:123.mp3|124.mp3" -acodec copy output.mp3

解释:

  • -i代表输入参数
  • contact:123.mp3|124.mp3代表着需要连接到一起的音频文件
  • -acodec copy output.mp3 重新编码并复制到新文件中

另一种方法是混合到一起

1
ffmpeg64.exe -i 124.mp3 -i 123.mp3 -filter_complex amix=inputs=2:duration=first:dropout_transition=2 -f mp3 remix.mp3

解释:

  • -i代表输入参数
  • -filter_complex ffmpeg滤镜功能,非常强大,详细请查看文档
  • amix是混合多个音频到单个音频输出
  • inputs=2代表是2个音频文件,如果更多则代表对应数字
  • duration 确定最终输出文件的长度
  • longest(最长)|shortest(最短)|first(第一个文件)
  • dropout_transition
    The transition time, in seconds, for volume renormalization when an input stream ends. The default value is 2 seconds.
  • -f mp3 输出文件格式

音频文件截取指定时间部分

1
ffmpeg64.exe -i 124.mp3 -vn -acodec copy -ss 00:00:00 -t 00:01:32 output.mp3

解释:

  • -i代表输入参数
  • -acodec copy output.mp3 重新编码并复制到新文件中
  • -ss 开始截取的时间点
  • -t 截取音频时间长度

音频文件格式转换

1
ffmpeg64.exe -i null.ape -ar 44100 -ac 2 -ab 16k -vol 50 -f mp3 null.mp3

解释:

  • -i代表输入参数
  • -acodec aac(音频编码用AAC)
  • -ar 设置音频采样频率
  • -ac 设置音频通道数
  • -ab 设定声音比特率
  • -vol <百分比> 设定音量

环境:centos 7 x86_64,php 7.1.7, MariaDB 10.1.23

一,下载sphinx,scws相关包

sphinx下载地址:http://sphinxsearch.com/downloads/release/

sphinx php扩展下载地址:http://pecl.php.net/package/sphinx

scws下载地址:http://www.xunsearch.com/scws/download.php

scws词库下载地址:http://www.xunsearch.com/scws/down/scws-dict-chs-utf8.tar.bz2

二,安装sphinx,scws,以及php扩展

  • 1,安装sphinx

    # cd sphinx-2.3.1-beta
    # ./configure --prefix=/usr/local/sphinx --with-mysql=/usr/local/mariadb LIBS=-liconv
    # make && make install

# cd /usr/local/src  
# wget http://www.xunsearch.com/scws/down/scws-1.2.3.tar.bz2
# tar xvjf scws-1.2.3.tar.bz2
# mkdir /usr/local/scws
# cd scws-1.2.3
# ./configure --prefix=/usr/local/scws/
# make && make install
  • 5,安装scws php扩展

# cd /usr/local/src/sphinx/scws-1.2.3/phpext    
# phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make && make install

  • 6 安装scws词库

# wget http://www.xunsearch.com/scws/down/scws-dict-chs-utf8.tar.bz2
# tar xvjf scws-dict-chs-utf8.tar.bz2 -C /usr/local/scws/etc/

# www为php-fpm运行用户
# chown www:www /usr/local/scws/etc/dict.utf8.xdb

在这里一定要加权限,也就是说让php-fpm或者php-cgi的运行用户,拥有dict.utf8.xdb的所有权限。如果不这么做的话,php 扩展调用词库会报如下错误:

1
Warning: SimpleCWS::add_dict(): Failed to add the dict file

怎么查看php-fpm,php-cgi的运行用户呢?

  • 2,配置sphinx.conf,加上以下内容
    其中searchd 以下3个配置比较重要。mysql -h0 -P 9306访问。9312可以给php访问。query_log_format 记录日志的格式。

  • 1 # php
    listen = 9312

  • 2 # mysql
    listen = 9306:mysql41

  • 3 # log_format

    query_log_format = sphinxql

  • sphinx.conf

WARNING: key 'sql_query_info' was permanently removed from Sphinx configuration. Refer to documentation for details.

  • 3,安装scws词库

# tar xvjf scws-dict-chs-utf8.tar.bz2 -C /usr/local/scws/etc/  

# chown tank:tank /usr/local/scws/etc/dict.utf8.xdb

在这里一定要加权限,也就是说让php-fpm或者php-cgi的运行用户,拥有dict.utf8.xdb的所有权限。如果不这么做的话,php 扩展调用词库会报如下错误:

1
Warning: SimpleCWS::add_dict(): Failed to add the dict file

怎么查看php-fpm,php-cgi的运行用户呢?

# vim /etc/php.ini  
[sphinx]
extension = sphinx.so

[scws]
extension = scws.so
scws.default.charset = utf-8
scws.default.fpath = /usr/local/scws/etc

四,启动sphinx,php-fpm

  • 1,启动sphinx
    1
    2
    # /usr/local/sphinx2/bin/indexer --config /usr/local/sphinx2/etc/sphinx.conf --all  
    # /usr/local/sphinx2/bin/searchd --config /usr/local/sphinx2/etc/sphinx.conf
  • 2,重启php-fpm
    1
    # /etc/init.d/php-fpm restart  
    前二次,我安装sphinx,必须在mysql中安装sphinx存储插件,而这次没有,看下图

五,测试sphinx全文检索

  • 1,命令行的测试

1、meta标签实现 只需在head里加上下面这一句就行了,在当前页面停留0.1秒后跳转到目标页面

1
<meta http-equiv="refresh" content="0.1; url=http://baidu.cn/">

2、Javascript实现

  • 方法一:这个方法比较常用

    1
    window.location.href = "http://baidu.cn/";
  • 方法二:

    1
    self.location = "http://baidu.cn/";
  • 方法三:

    1
    top.location = "http://baidu.cn/";
  • 方法四:
    只对IE系列浏览器有效,实用性不大

    1
    window.navigate("http://baidu.cn/");

3、php实现

1

3
<?php
header("Location: http://baidu.cn/");
?>

nginx维护页面处理-全部URL指向同一个页面
一般来说nginx的维护页面需要把所有访问本站的链接全部重定向到某个指定页面

1.rewrite

1
rewrite ^(.*)$ /maintain.html break;

注意这句后面如果有重定向等语句,那么后面执行的重定向等语句需要全部注释掉

2.使用状态码

1
2
3
4
5
location /{
return 503;
}
#注意其他location优先级高的匹配均需要注释掉
error_page 503 /maintain.html;

每当服务器遇到 502 代码时,就自动转到临时维护的静态页:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
server {
listen 80;
server_name mydomain.com;

# ... 省略掉 N 行代码


error_page 502 = @tempdown;

location @tempdown {
rewrite ^(.*)$ /pages/maintain.html break;
}
}

如果你只想要【临时维护页面】就这样写(适合服务器更新东西或者改版):

1
2
3
4
5
6
7
8
9
10
server {
listen 80;
server_name mydomain.com;

# ... 省略掉 N 行代码

# 所有页面都转跳到维护页
rewrite ^(.*)$ /pages/maintain.html break;

}

* 注:*
* 临时维护页要找对正确的路径,我的例子是 http://mydomain.com/page/maintain.html。所以路径是 /page/maintain.html *

STEP1

A1.1是新文件夹,A1.0是旧文件夹,out是放置 A1.0到A1.1的保持目录结构的增量文件。

1
rsync --dry-run -rcnC --out-format="%n"  A1.1/  A1.0/

注意该处的-C参数是按照cvs的ignore规则来过滤不需要同步的文件,在CVS中,默认是不会提交二进制文件的,所以如果需要进行二进制文件提取,那就不要加C.
执行了该命令后,得到了一个A1目录的文件列表:

1
2
3
4
A1.1/system/app/
A1.1/system/app/A.apk
A1.1/system/app/B.apk
A1.1/system/app/C.apk

也就是差异文件,由于这里默认会显示出文件夹,所以要过滤掉以『/』结尾的文件夹的显示

1
rsync --dry-run -rcnC --out-format="%n"  A1.1/  A1.0/ |grep -v "/$"

这样就得到了一个纯增量文件的列表

STEP2

有了文件列表,复制的操作方法就很多了。可以继续使用rsync同步到新的out目录,以防止多次执行后错误文件修复问题
完整代码

1
rsync --dry-run -rcnC --out-format="%n"  A1.1/  A1.0/ |grep -v "/$"|xargs -I{} rsync -R A1/./{} out/

昨天一位 VPS 客户说他的 WordPress 博客没了,网站可以打开,但是文章都没了,怀疑被黑。我们登陆客户 VPS 后没发现被黑迹象,然后进入 MySQL 数据库发现 Table ‘./wordpress/wp_posts’ is marked as crashed and should be repaired 错误,因为 wp_posts 表被损坏了,所以 WordPress 的文章都显示不出来:

mysql> use wordpress;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> select * from wp_posts;
ERROR 145 (HY000): Table './wordpress/wp_posts' is marked as crashed and should be repaired
mysql> Bye

修复 MySQL 数据库数据表问题可以由 mysqlcheck 来解决,先用 mysqlcheck 查看一下:

1
2
# mysqlcheck -u root -p wordpress
Enter password:

然后添加 –auto-repair 参数自动修复,最好修复前备份一下数据库:
