第十一章 Nginx之服务代理

一、数据库迁移

1.常见原因

1.数据库要做升级
2.数据库服务器到期需要迁移

2.新服务器搭建数据库

[root@db02 ~]# yum install -y mariadb-server

3.启动

[root@db02 ~]# systemctl start mariadb
[root@db02 ~]# systemctl enable mariadb

4.配置数据库密码

[root@db02 ~]# mysqladmin -uroot password 'Linhd@123'

5.密码连接数据库

[root@db02 ~]# mysql -uroot -p
Enter password:

6.旧数据库导出数据

[root@db01 ~]# mysqldump -uroot -p -B wordpress zh edusoho > /tmp/full.sql 
Enter password: 
[root@db01 ~]# ll /tmp/full.sql 
-rw-r--r-- 1 root root 1244924 Aug 28 16:46 /tmp/full.sql

7.新库授权

MariaDB [(none)]> grant all on *.* to root@'172.16.1.%' identified by '123456';
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> grant all on wordpress.* to wp@'172.16.1.%' identified by '123';
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> grant all on zh.* to zh@'172.16.1.%' identified by '234';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> grant all on edusoho.* to edu@'172.16.1.%' identified by '345';
Query OK, 0 rows affected (0.00 sec)

8.将数据导入新库

[root@db01 ~]# mysql -uroot -p -h172.16.1.52 < /tmp/full.sql 
Enter password: 123456

9.修改项目配置

1)wordpress代码

[root@web01 ~]# vim /code/wordpress/wp-config.php
/** WordPress数据库的名称 */
define('DB_NAME', 'wordpress');

/** MySQL数据库用户名 */
define('DB_USER', 'wp');

/** MySQL数据库密码 */
define('DB_PASSWORD', '123');

/** MySQL主机 */
define('DB_HOST', '172.16.1.52');

2)知乎代码

[root@web01 ~]# vim /code/zh/system/config/database.php 
<?php

$config['charset'] = 'utf8';^M
$config['prefix'] = 'aws_';^M
$config['driver'] = 'MySQLi';^M
$config['master'] = array (
  'charset' => 'utf8',
  'host' => '172.16.1.52',
  'username' => 'zh',
  'password' => '234',
  'dbname' => 'zh',
);^M
$config['slave'] = false;^M

3)edusoho代码

[root@web01 ~]# vim /code/edusoho/app/config/parameters.yml 
parameters:
    database_driver: pdo_mysql
    database_host: 172.16.1.52
    database_port: 3306
    database_name: edusoho
    database_user: edu
    database_password: '345'

10.排错

1.查看浏览器检查,找到出问题的接口或者文件页面
2.查看日志
	[root@web01 ~]# ll /var/log/nginx/access.log
	[root@web01 ~]# ll /var/log/nginx/error.log
	业务进程日志
3.把日志给开发
4.4xx自己解决
5.5xx给开发

二、拆分PHP

1.修改nginx配置

[root@web01 ~]# vim /etc/nginx/conf.d/linux.blog.com.conf 
server {
    listen 80;
    server_name linux.blog.com;
    root /code/wordpress;
    location / {
        index index.php;
    }
    location ~* \.php$ {
        fastcgi_pass 172.16.1.8:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

2.重启访问

[root@web01 ~]# systemctl restart nginx

#访问页面http://linux.blog.com/,报错502

3.修改PHP监听端口

[root@web02 ~]# vim /etc/php-fpm.d/www.conf
#修改监听地址
listen = 172.16.1.8:9000
#修改允许连接的ip地址
listen.allowed_clients = 172.16.1.7

#重启服务
[root@web02 /code]# systemctl restart php-fpm

4.再次访问页面

#报错页面找不到或者文件找不到

5.同步nginx站点文件

[root@web01 /code]# scp -r wordpress 172.16.1.8:/code/

6.再次访问测试

#图片丢失

7.php服务器挂载

[root@web02 /code]# mount -t nfs 172.16.1.31:/data/wp /code/wordpress/wp-content/uploads

8.再次访问测试没有问题

三、数据文件实时备份

1.服务端(backup)

1)安装

[root@backup ~]# yum install -y rsync

2)配置rsync

[root@backup ~]# vim /etc/rsyncd.conf 
uid = www
gid = www
port = 873
fake super = yes
use chroot = no
max connections = 200
timeout = 600
ignore errors
read only = false
list = false
auth users = rsync_backup
secrets file = /etc/rsync.passwd
log file = /var/log/rsyncd.log
#####################################
[data]
comment = welcome to oldboyedu backup!
path = /data

3)创建用户

[root@backup ~]# groupadd www -g 666
[root@backup ~]# useradd www -u 666 -g 666

4)创建密码文件

[root@backup ~]# echo "rsync_backup:123456" > /etc/rsync.passwd
[root@backup ~]# chmod 600 /etc/rsync.passwd

5)创建目录

[root@backup ~]# mkdir /data
[root@backup ~]# chown -R www.www /data/

6)启动

[root@backup ~]# systemctl start rsyncd
[root@backup ~]# ps -ef | grep rsync

2.客户端

1)安装

[root@nfs ~]# yum install -y rsync inotify-tools

#安装sersync
[root@nfs ~]# tar xf sersync2.5.4_64bit_binary_stable_final.tar.gz -C /usr/local/sersync

2)配置sersync

[root@nfs ~]# vim /usr/local/sersync/confxml.xml

3)创建密码文件

[root@nfs ~]# echo 123456 > /etc/rsync.password
[root@nfs ~]# chmod 600 /etc/rsync.password

4)启动

[root@nfs /data]# /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml.xml

3.测试

四、代理

1.什么是代理

代理一词往往并不陌生, 该服务我们常常用到如(代理理财、代理租房、代理收货等等),如下图所示

1

2.没有代理

在没有代理模式的情况下,客户端和Nginx服务端,都是客户端直接请求服务端,服务端直接响应客户端。

2

3.有代理

那么在互联网请求里面,客户端往往无法直接向服务端发起请求,那么就需要用到代理服务,来实现客户端和服务通信,如下图所示  

3

4.代理常见模式

Nginx作为代理服务,按照应用场景模式进行总结,代理分为
1.正向代理
2.反向代理

1)正向代理

正向代理,(内部上网)客户端<—>代理->服务端

4

2)反向代理

反向代理,用于公司集群架构中,客户端->代理<—>服务端

5

3)正向代理与反向代理区别

1.区别在于形式上服务的"对象"不一样
2.正向代理代理的对象是客户端,为客户端服务
3.反向代理代理的对象是服务端,为服务端服务

五、Nginx代理服务支持协议

1.支持的协议

6

2.代理的模式

7

3.代理模块

反向代理模式与Nginx代理模块总结如表格所示
反向代理模式 Nginx配置模块
http、websocket、https、tomcat(java程序) ngx_http_proxy_module
fastcgi(PHP程序) ngx_http_fastcgi_module
uwsgi(python程序) ngx_http_uwsgi_module
grpc(go程序)(golang) ngx_http_v2_module

六、nginx代理配置

1.代理语法

Syntax:    proxy_pass URL;
Default:    —
Context:    location, if in location, limit_except

2.环境准备

主机 IP 身份
lb01 10.0.0.4,172.16.1.4 代理
web01 172.16.1.7 服务端

3.配置web01页面

[root@web01 ~]# vim /etc/nginx/conf.d/linux.proxy.com.conf
server {
    listen 80;
    server_name linux.proxy.com;

    location / {
        root /code/proxy;
        index index.html;
    }
}

[root@web01 ~]# systemctl restart nginx

4.编写网站

[root@web01 ~]# mkdir /code/proxy
[root@web01 ~]# vim /code/proxy/index.html
web01 .............

5.访问测试

#配置本地hosts
网页访问linux.proxy.com

6.配置代理

#安装nginx
#配置nginx
#创建用户
#配置站点配置文件
[root@lb01 ~]# vim /etc/nginx/conf.d/daili.conf
server {
    listen 80;
    server_name linux.proxy.com;

    location / {
        proxy_pass http://172.16.1.7:80;
        #proxy_pass http://10.0.0.7:80;		#正常情况我们使用内网IP,抓包测试使用外网
    }
}
[root@lb01 ~]# systemctl start nginx

7.访问页面测试

#访问http://linux.proxy.com/返回结果不是我们要的内容
原因:
	代理请求后端时,没有使用域名,是使用IP访问的,匹配的配置文件是nginx中第一个配置文件

8.配置携带域名去代理

[root@lb01 ~]# vim /etc/nginx/conf.d/daili.conf 
server {
    listen 80;
    server_name linux.proxy.com;

    location / {
        proxy_pass http://10.0.0.7:80;
        proxy_set_header Host $http_host;
    }
}

作业

1.恢复快照
2.搭建两台LNMP
3.数据库独立
4.文件共享
5.文件实时备份
6.代理一台机器
主机 IP 服务
web01 172.16.1.7 WordPress Nginx PHP
web02 172.16.1.8 WordPress Nginx PHP
db01 172.16.1.51 MariaDB
NFS 172.16.1.31 NFS Rsync sersync
backup 172.16.1.41 Rsync inotify
lb01 172.16.1.4 Nginx代理

# 创建密码文件
[root@nfs ~]# echo 123456 > /etc/rsync.password
[root@nfs ~]# chmod 600 /etc/rsync.password

# 查看启动参数
[root@nfs ~]# /usr/local/sersync/sersync2 -h
set the system param
execute:echo 50000000 > /proc/sys/fs/inotify/max_user_watches
execute:echo 327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
_______________________________________________________
参数-d:启用守护进程模式
参数-r:在监控前,将监控目录与远程主机用rsync命令推送一遍
c参数-n: 指定开启守护线程的数量,默认为10个
参数-o:指定配置文件,默认使用confxml.xml文件
参数-m:单独启用其他模块,使用 -m refreshCDN 开启刷新CDN模块
参数-m:单独启用其他模块,使用 -m socket 开启socket模块
参数-m:单独启用其他模块,使用 -m http 开启http模块
不加-m参数,则默认执行同步程序

# 指定配置文件(同步多个)
[root@nfs /web_upload]# /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml.xml
set the system param
execute:echo 50000000 > /proc/sys/fs/inotify/max_user_watches
execute:echo 327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
option: -d 	run as a daemon
option: -r 	rsync all the local files to the remote servers before the sersync work
option: -o 	config xml name:  /usr/local/sersync/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost	host port: 8008
will ignore the inotify createFile event 
daemon start,sersync run behind the console 
use rsync password-file :
user is	gjs_backup
passwordfile is 	/etc/rsync.passwd
config xml parse success
please set /etc/rsyncd.conf max connections=0 Manually
sersync working thread 12  = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads) 
Max threads numbers is: 22 = 12(Thread pool nums) + 10(Sub threads)
please according your cpu ,use -n param to adjust the cpu rate
------------------------------------------
rsync the directory recursivly to the remote servers once
working please wait...
execute command: cd /data && rsync -artuz -R --delete ./ rsync_backup@172.16.1.41::data --password-file=/etc/rsync.password >/dev/null 2>&1 
run the sersync: 
watch path is: /data

# 手动推送一遍
[root@nfs ~]# cd /data && rsync -artuz -R --delete ./ rsync_backup@172.16.1.41::data --password-file=/etc/rsync.password

6.配置代理

# 配置nginx官方源,安装nginx
# 安装nginx
[root@web01 ~]# vim /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

# 依赖安装
[root@web01 ~]# yum install -y gcc gcc-c++ autoconf pcre pcre-devel make automake wget httpd-tools vim tree
[root@web01 ~]# yum install -y nginx

# 配置Nginx
[root@web01 ~]# vim /etc/nginx/nginx.conf 
user  www;

# 创建用户
[root@web01 ~]# groupadd www -g 666
[root@web01 ~]# useradd www -u 666 -g 666 -s /sbin/nologin -M


# 配置携带域名去代理
[root@lb01 ~]# vim /etc/nginx/conf.d/daili.conf 
server {
    listen 80;
    server_name xss.blog.com;

    location / {
        proxy_pass http://10.0.0.7:80;
        proxy_set_header Host $http_host;
    }
}

# 启动Nginx
[root@lb01 ~]# systemctl start nginx

# 查看是否启动
[root@web01 ~]# ps -ef | grep nginx
