docker 启动MySQL5.6，并映射数据、端口和配置文件

docker run --name mysql56 -v /mnt/mysql56:/var/lib/mysql -v /mnt/mysql56confd:/etc/mysql/conf.d -p 3308:3306 -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6

# 说明 映射到真机3308端口
# 数据文件存放在/mnt/mysql56下
# 配置文件映射到/mnt/mysql56confd 需要修改的配置在这个文件夹新建配置文件即可

docker run –name xx_mysql -v D:\mysql\xx\data:/var/lib/mysql -v D:\mysql\xx\conf.d:/etc/mysql/conf.d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 –restart always -d mysql:8

你可能想直知道conf.d文件夹默认是啥，其实基本啥也没有

Composer Installation – Windows

Using the Installer#

This is the easiest way to get Composer set up on your machine.

Download and run Composer-Setup.exe. It will install the latest Composer version and set up your PATH so that you can call composer from any directory in your command line.

Note: Close your current terminal. Test usage with a new terminal: This is important since the PATH only gets loaded when the terminal starts.

Manual Installation#

Change to a directory on your PATH and run the installer following the Download page instructions to download composer.phar.

Create a new composer.bat file alongside composer.phar:

Using cmd.exe:

C:\bin> echo @php "%~dp0composer.phar" %*>composer.bat

Using PowerShell:

PS C:\bin> Set-Content composer.bat '@php "%~dp0composer.phar" %*'

Add the directory to your PATH environment variable if it isn’t already. For information on changing your PATH variable, please see this article and/or use your search engine of choice.

Close your current terminal. Test usage with a new terminal:

C:\Users\username>composer -V
Composer version 1.0.0 2016-01-10 20:34:53

solr: Could not start JMX monitoring

删除core重来！

logs/solr.log:Caused by: java.io.IOException: Cannot bind to URL [rmi://noq5ay.s0x.cn/aa]: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:

疑似被攻击

被入侵后会多个.json文件 清理下不知道会好不，我这边是直接备份下配置文件删除core重来

pageYOffset 属性是 scrollY 属性的别名

pageYOffset 属性是 scrollY 属性的别名：

window.pageYOffset == window.scrollY; // 总是返回 true

为了跨浏览器兼容，请使用 window.pageYOffset 代替 window.scrollY。另外，旧版本IE（<9）两个属性都不支持，必须使用其他的非标准属性。完整的兼容性代码如下：

var supportPageOffset = window.pageXOffset !== undefined;
var isCSS1Compat = ((document.compatMode || "") === "CSS1Compat");

var x = supportPageOffset ? window.pageXOffset : isCSS1Compat ? document.documentElement.scrollLeft : document.body.scrollLeft;
var y = supportPageOffset ? window.pageYOffset : isCSS1Compat ? document.documentElement.scrollTop : document.body.scrollTop;

solr init note

cd /usr/local/src/solr-8.5.2/ \
&& ./bin/solr stop -all \
&& rm -f /etc/default/solr.in.sh \
&& rm -f /etc/init.d/solr \
&& rm -rf /usr/local/solr \
&& mkdir /usr/local/solr \
&& rm -rf /mnt/solr \
&& mkdir /mnt/solr \
&& chown solr:solr -R /mnt/solr \
&& chmod 775 /mnt/solr \
&& ./bin/install_solr_service.sh /usr/local/src/solr-8.5.2.zip -d /mnt/solr -i /usr/local/solr -f -s solr -n

client_max_body_size、post_max_size、upload_max_filesize

Syntax:client_max_body_size size;
Default:client_max_body_size 1m;
Context:http, server, location
决定post上传文件大小的上限，1m肯定不够用，设置为0表示不做大小检查

post_max_size = 128M; php的post最大大小限制

upload_max_filesize = 128M; php的单个文件大小的限制

PHP里通常需要3者结合才能解除文件上传大小限制。
