Mysql

官方下载 社区开源免费版

下载网页 https://dev.mysql.com/downloads/file/?id=474703

云服下载太慢了， 本地下载在上传到服务器

下载rpm包

https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.21-1.el6.x86_64.rpm-bundle.tar

解压tar

$ tar xf mysql-5.7.21-1.el6.x86_64.rpm-bundle.tar
mysql-community-client-5.7.21-1.el6.x86_64.rpm 
mysql-community-embedded-5.7.21-1.el6.x86_64.rpm

mysql-community-common-5.7.21-1.el6.x86_64.rpm  
mysql-community-embedded-devel-5.7.21-1.el6.x86_64.rpm 
mysql-community-server-5.7.21-1.el6.x86_64.rpm
mysql-community-devel-5.7.21-1.el6.x86_64.rpm   
mysql-community-libs-5.7.21-1.el6.x86_64.rpm            
mysql-community-test-5.7.21-1.el6.x86_64.rpm

按照以下顺序进行安装，因为它们之间存在依赖关系
common --> libs --> clients --> server

$ rpm -ivh mysql-community-common-5.7.21-1.el6.x86_64.rpm

安装时抛错 --force --nodeps 完美解决 原因：这是由于yum安装了旧版本的GPG keys造成的

参考地址： https://www.cnblogs.com/royfans/p/7243641.html

$ rpm -ivh mysql-community-libs-compat-5.7.21-1.el6.x86_64.rpm --force --nodeps
$ rpm -ivh mysql-community-client-5.7.21-1.el6.x86_64.rpm --force --nodeps

$ groupadd mysql
$ useradd -s /sbin/nologin -g mysql mysql

创建data目录和mysql-files目录，并修改权限

$ mkdir -p /usr/local/mysql/data
$ mkdir -p /usr/local/mysql/mysql-files
$ chown -R root:mysql /usr/local/mysql
$ chown -R mysql:mysql /usr/local/mysql/data
$ chown -R mysql:mysql /usr/local/mysql/mysql-files

Supervisor

(参考文献：http://blog.csdn.net/xyang81/article/details/51555473)

安装python包管理工具(easy_install)

easy_install是setuptools包里带的一个命令，使用easy_install实际上是在调用setuptools来完成安装模块的工作,所以安装setuptools即可。

$ wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

安装supervisor

$ easy_install supervisor

运行echo_supervisord_conf程序生成supervisor的初始化配置文件详情查看：
http://supervisord.org/configuration.html

$  mkdir /etc/supervisor
$  echo_supervisord_conf > /etc/supervisor/supervisord.conf

启动Supervisor服务

$ supervisord -c /etc/supervisor/supervisord.conf

启用php-fpm

#优化php-fpm配置后 检测配置  dynamic 模式 使用socket方式连接

[root@centos sbin]# /usr/local/php7/sbin/php-fpm -c /usr/local/php7/etc/php.ini -y /usr/local/php7/etc/php-fpm.conf -t
[08-Apr-2018 15:54:10] NOTICE: configuration file /usr/local/php7/etc/php-fpm.conf test is successful

[root@centos sbin]# /usr/local/php7/sbin/php-fpm -c /usr/local/php7/etc/php.ini -y /usr/local/php7/etc/php-fpm.conf 
[root@centos sbin]# ps -ef |grep php-fpm

...... 启了50个进程

php-fpm 加入 service 服务

1)、设置php-fpm.conf，将;pid = run/php-fpm.pid前面分号去掉
2)、将解压后的php文件夹下的init.d.php-fpm拷贝到/etc/init.d/php-fpm
$ cp /usr/local/src/php7/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
3)、将解压后的php文件夹下的init.d.php-fpm拷贝到/etc/init.d/php-fpm
4)、修改 php-fpm 文件
将

$ php_fpm_BIN=@sbindir@/php-fpm
$ php_fpm_CONF=@sysconfdir@/php-fpm.conf
$ php_fpm_PID=@localstatedir@/run/php-fpm.pid

改成

$ php_fpm_BIN=/usr/local/php7/sbin/php-fpm
$ php_fpm_CONF=/usr/local/php7/etc/php-fpm.conf
$ php_fpm_PID=/usr/local/php7/var/run/php-fpm.pid

5)、执行

$ chmod +x /etc/init.d/php-fpm
$ chkconfig --add php-fpm
$ chkconfig php-fpm on
$ service php-fpm status
    php-fpm (pid 814) is running...

以后可以使用如下命令管理php-fpm了

$ service php-fpm start
$ service php-fpm stop
$ service php-fpm restart
$ service php-fpm reload

使用 Redis 管道提升性能
2018年2月08日 738 汉字 2 围观 0 评论 数据库 redis

在高并发和高性能的应用中，优化数据库操作是至关重要的。Redis 作为一种高性能的内存数据库，提供了管道（Pipeline）功能，允许客户端一次性发送多个命令。这种方式可以显著减少网络延迟，提高性能。本文将深入探讨如何使用 Redis 管道提升性能，并提供示例代码。

1. 什么是 Redis 管道？

Redis 管道是一种技术，它允许客户端在一次网络请求中发送多个命令，而不需要等待每个命令的响应。这意味着可以减少网络往返的次数，从而提高操作的性能。管道的主要优点在于：

  • 减少网络延迟：通过批量发送命令，减少了多次连接的开销。
  • 提高吞吐量：可以一次性处理多个命令，提升处理能力。

2. 使用场景

Redis 管道非常适合以下场景：

  • 批量写入：在需要批量插入数据时，使用管道可以显著提高写入速度。
  • 批量读取：在需要读取大量数据时，管道也可以减少延迟。
  • 高频操作：在高频率调用 Redis 的场景下，使用管道可以提升性能。

3. 使用 Redis 管道的基本示例

3.1 安装 Redis 客户端

在使用管道之前，您需要安装 Redis 客户端。以 PHP 为例，您可以使用 Predis 或 phpredis 等库。

composer require predis/predis

3.2 使用管道的示例代码

以下是一个使用 PHP 和 Predis 实现 Redis 管道的示例：

<?php
require 'vendor/autoload.php';

$client = new Predis\Client();

// 开始管道
$client->pipeline(function ($pipe) {
    for ($i = 0; $i < 1000; $i++) {
        $pipe->set("key:$i", "value:$i");
    }
});

// 结束管道
echo "1000 keys have been set using pipeline.\n";
?>

在这个示例中，我们使用管道批量设置 1000 个键值对，只需一次网络请求即可完成。

3.3 读取数据的示例

同样，我们可以使用管道批量读取数据：

<?php
$client = new Predis\Client();

// 开始管道
$responses = $client->pipeline(function ($pipe) {
    for ($i = 0; $i < 1000; $i++) {
        $pipe->get("key:$i");
    }
});

// 输出结果
foreach ($responses as $response) {
    echo $response . "\n";
}
?>

在这个示例中，我们同样使用管道批量获取 1000 个键的值。

4. 性能测试

在实际应用中，您可以通过性能测试工具（如 Apache Benchmark 或 Siege）对比使用管道和不使用管道的性能差异。通常情况下，使用管道的方式会显著减少响应时间和提高吞吐量。

5. 注意事项

  • 命令顺序：管道中的命令是按照顺序执行的，确保命令之间的依赖关系。
  • 错误处理：在使用管道时，错误处理可能会变得复杂，因为所有命令的结果都在一个响应中返回。
  • 内存管理：在使用管道时，注意不要一次性发送过多的命令，以防造成内存占用过高。

6. 结论

Redis 管道是提升 Redis 性能的强大工具，通过批量发送命令，您可以显著减少网络延迟，提高应用的响应速度。在需要大量数据操作的场景下，合理使用管道将为您的应用带来显著的性能提升。希望本文能帮助您理解 Redis 管道的用法和优势。

Nginx实战之让用户通过用户名密码认证访问web站点
2018年2月03日 74 汉字 13 围观 0 评论 Nginx nginx

最近在读 <> 所以试试手;

nginx http_auth_basic_module 模块为默认模块 不需要再编译时配置 可以直接 auth_basic

在location块中设置

   location / {
        auth_basic "secret";
        auth_basic_user_file /usr/local/nginx/passwd.db;
    }
htpasswd -c /usr/local/nginx/passwd.db test //创建认证信息，test 为认证用户名
New password: *******  //输入认证密码
Re-type new password: ********  //再次输入认证密码

重启nginx

nginx -s reload

亲测有效
