nginx做负载均衡服务器，配置动静分离
文章目录
1. 题目：
后端RS服务器⼀台部署LNMP(nginx1.22+mysql8.0+php8.0)，⼀台部署
httpd。
要求nginx和php使⽤编译安装
最后要通过访问nginx负载均衡服务器的IP看到动静分离的效果。
2. 环境和提供软件包
2.1 提供软件包
[root@node6 ~]# wget https://nginx.org/download/nginx-1.22.0.tar.gz https://www.php.net/distributions/php-8.0.23.tar.gz
[root@node6 ~]# ls
anaconda-ks.cfg nginx-1.22.0.tar.gz
mysql-8.0.20-linux-glibc2.12-x86_64.tar.xz php-8.0.23.tar.gz
[root@node6 ~]#
2.2 环境
| 主机 | ip | 安装的服务 |
|---|---|---|
| node6 | 192.168.232.134 | lnmp，动态资源 |
| node3 | 192.168.232.128 | nginx，静态资源 |
| node2 | 192.168.232.129 | nginx，做负载均衡 |
- 关闭防火墙
[root@node6 ~]# systemctl disable --now firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@node6 ~]# vim /etc/selinux/config
[root@node6 ~]# setenforce 0
[root@node3 ~]# systemctl disable --now firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@node3 ~]# setenforce 0
[root@node3 ~]# vi /etc/selinux/config
[root@node2 ~]# systemctl disable --now firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@node2 ~]# setenforce 0
[root@node2 ~]# vi /etc/selinux/config
3. 在134主机主机部署lnmp，做动态资源
3.1 源码安装nginx
创建系统用户nginx
[root@node6 ~]# useradd -r -M -s /sbin/nologin nginx
[root@node6 ~]#
安装依赖环境
[root@node6 ~]# yum -y groups mark install 'Development Tools'
[root@node6 ~]# yum -y install pcre-devel openssl openssl-devel gd-devel gcc gcc-c++ make
创建日志存放目录
[root@node6 ~]# mkdir -p /var/log/nginx
[root@node6 ~]# chown -R nginx.nginx /var/log/nginx
[root@node6 ~]# ll -d /var/log/nginx
drwxr-xr-x. 2 nginx nginx 6 Sep 5 18:43 /var/log/nginx
编译安装
[root@node6 ~]# tar xf nginx-1.22.0.tar.gz
[root@node6 ~]# cd nginx-1.22.0
[root@node6 nginx-1.22.0]# ./configure \
--prefix=/usr/local/nginx \

--error-log-path=/var/log/nginx/error.log
[root@node6 nginx-1.22.0]# make
[root@node6 nginx-1.22.0]# make install
nginx安装后配置
[root@node6 ~]# echo 'export PATH=/usr/local/nginx/sbin:$PATH' > /etc/profile.d/nginx.sh
[root@node6 ~]# source /etc/profile.d/nginx.sh
启动nginx
[root@node6 ~]# nginx

我用Python分析了1500家电商的销售数据，竟发现了进口车厘子的秘密_爬虫 淘宝车厘子-程序员宅基地
文章浏览阅读519次，点赞2次，收藏2次。图片来源：互联网众所周知，中国是智利车厘子最主要的出口对象，占据了其95%的市场份额。智利驻华大使馆商务参赞娜塔曾表示：“2020-2021产季车厘子实现了丰收，预计今年有50万吨左右的车厘子进入中国市场。”自2020年12月中旬开始，智利海运车厘子陆续到达中国，运输成本较此前空运方式大幅下滑。这意味着，国内消费者将能以更低的价格买到车厘子。然而，近日国内已有多地进口车厘子核酸检测结果为阳性，在这种情况下，你还敢大呼“车厘子自由”吗？01 数据获取本文利用Python采集了淘宝网1585.._爬虫 淘宝车厘子
列式存储-程序员宅基地
文章浏览阅读1.1k次。OLAP中数据存储的问题OLAP 需要队列进行选择，行式存储按行存数据，使用索引加快对数据的查找（索引包括聚集索引（表记录的排列顺序与索引的排列顺序一致）和非聚簇索引（非聚集索引指定了表中记录的逻辑顺序，但记录的物理顺序和索引的顺序不一致））。这种方式对按列的存储和检索不是很高效，查询某一列数据需要将所有行的数据扫描一次，而且对统计分析也不友好。列式存储原理若使用列式存储可以只用扫描出需要的列，行、列存储的对比。文件格式parquet 文件格式：如下图所示：parquet file = hea_列式存储
