nginx部署wordpress架构

实验环境

（nginx） 10.20.20.3

（WordPress nginx PHP） 10.20.20.4 10.20.20.5

（mysql 主从） 10.20.20.6 10.20.20.7

查看Word

Press支持的mysql版本

数据库主从设置

安装依赖包

yum install libaio* -y

官网下载包二进制安装

脚本安装 #脚本练习我QQ 790827253

传入包安装mysql

10.20.20.6 （主） 10.20.20.7（从）

主配置

vim /etc/my.cof

#master

[mysqld]

socket=/var/lib/mysql/mysql.sock

user=mysql

symbolic-links=0

datadir=/data/mysql

innodb_file_per_table=1

server-id=1

log-error=/data/mysql/mysql_error.txt

log-bin=/data/mysql/master-log

[client]

port=3306

socket=/var/lib/mysql/mysql.sock

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/tmp/mysql.sock

创建库用户

create database test1;

GRANT REPLICATION SLAVE,REPLICATION CLIENT ON *.* TO ‘dbb’@’10.20.20.%’ IDENTIFIED BY ‘123456’;

grant replication slave on *.* to “dbb”@”10.20.20.%” identified by ‘123456’;

如果主数据库之前有数据要把数据导出来然后让从数据库同步

要把日志改成数据大的时候

导出文件

/usr/local/mysql/bin/mysqldump –all-databases –single_transaction –flush-logs –master-data=2 –lock-tables > /opt/backup.sql

传入从

scp /opt/backup.sql 10.20.20.7:/opt/

/etc/init.d/mysqld restart

查看二进制日志

从配置

vim /etc/my.cof

#slave

[mysqld]

socket=/var/lib/mysql/mysql.sock

user=mysql

symbolic-links=0

datadir=/data/mysql

innodb_file_per_table=1

server-id=10

#log-bin=/data/mysql/master-log

relay-log = /data/mysql

[client]

port=3306

socket=/var/lib/mysql/mysql.sock

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/tmp/mysql.sock

#mysql < /opt/backup.sql #slave 导入sql文件数据

CHANGE MASTER TO MASTER_HOST=’10.20.20.6′,MASTER_USER=’dbb’,MASTER_PASSWORD=’123456′,MASTER_LOG_FILE=’master-log.000002′,MASTER_LOG_POS=950;

验证

show databases;

start slave ；

show slave status\G

主从复制的问题

1 防火墙是否关闭

2 日志一定要同步到正确的时候

3 使用reset slave 清除同步信息 reset maser

启动

/usr/local/php/sbin/php-fpm

（WordPress nginx）10.20.20.4 10.20.20.5

安装nginx

配置官方yum源

或者编译安装

俩个服务器都是一样的配置

编译安装过程

cd /usr/local/scr/

传入安装包 1.12

解压缩

tar xvf

cd 进去编译

./configure –prefix=/usr/local/nginx –with-pcre –with-http_stub_status_module –with-http_ssl_module

make && make install

配置文件在

/usr/local/nginx/conf/nginx.conf

#mkdir /data/nginx/wordpress –p

#chown www.www /usr/local/nginx/ /data/nginx/ -R

location / {

root /code/wordpress;

index index.php index.html index.htm;

if ($http_user_agent ~ “ApacheBench|WebBench|TurnitinBot|Sogou web spider|Grid Service”) {

proxy_pass http://www.baidu.com;

return 403;

}

location ~ \.php$ {

root /code/wordpress;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

1.4：创建php测试页：

# cat /data/nginx/wordpress/index.php

<?php

phpinfo();

1.6：准备数据库：

mysql> CREATE DATABASE wordpress;

创建的用户是负载均衡的ip地址这里是0.20.20.3

mysql> GRANT ALL PRIVILEGES ON *.* TO “dbb”@”10.20.20.%” IDENTIFIED BY “123456”;

mysql> FLUSH PRIVILEGES;

部署WordPress：

[root@redis-s4 wordpress]# pwd

/data/nginx/wordpress

# tar xvf wordpress-5.0.1-zh_CN.tar.gz

# mv wordpress-5.0.1-zh_CN.tar.gz /opt

# cp wp-config-sample.php wp-config.php

#vim wp-config.php #修改数据库配置

# grep “^[a-Z]” wp-config.php

wp-config.php 文件中的主机不是mysql的地址而是负载均衡的nginxip 10.20.20.3 独立的

访问网站得到的替换在下面

测试并启动Nginx：

[root@redis-s4 wordpress]# /usr/local/nginx/sbin/nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

[root@redis-s4 wordpress]# /usr/local/nginx/sbin/nginx

部署博客产品Wordpress

1) 配置Nginx虚拟主机站点，域名为

www.dbb.com

#1.nginx具体配置信息

[root@nginx ~]# cat /etc/nginx/conf.d/wordpress.conf

server {

listen 80;

server_name www.dbb.com;

root /code/wordpress;

index index.php index.html;

location ~ \.php$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

2) 重启nginx服务

[root@nginx ~]# systemctl restart nginx

3) 获取wordpress产品，解压并部署wordress

[root@nginx ~]# mkdir /code

[root@nginx ~]# cd /code

[root@nginx code]# wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz

[root@nginx ~]# tar xf wordpress-4.9.4-zh_CN.tar.gz

[root@nginx ~]# chown -R www.www /code/wordpress/

tar xf wordpress-4.9.4-zh_CN.tar.gz -C /code/

cp wp-config-sample.php wp-config.php

cd /cxldata/www/wordpress

vi wp-config.php

#添加三行

define(“FS_METHOD”, “direct”);

define(“FS_CHMOD_DIR”, 0777);

define(“FS_CHMOD_FILE”, 0777);

wp-config.php 文件中的主机不是mysql的地址而是负载均衡的nginxip 10.20.20.3 独立的

4) 由于wordpress产品需要依赖数据库, 所以需要手动建立数据库

[root@nginx ~]# mysql -uroot -pBgx123.com

mysql> create database wordpress;

mysql> exit

create database wordpress;

grant all on *.* to dbb@’10.20.20.3′ identified by ‘123456’;

（nginx） 10.20.20.3

使用nginx负载均衡

同样安装nginx

安装mysql

连接主mysql的服务器

mysql -udeng -h10.20.20.6 -p123456

配置负载均衡

vim /etc/nginx/nginx.cof

stream {

upstream mysql {

server 10.20.20.6:3306;

}

server {

listen 10.20.20.3 :3306;

proxy_pass mysql;

}

启动nginx

nginx -t

nginx -s reload

端口是否打开

如果nginx启动错误

nginx: [error] open() “/Var/run/Nginx.pid” failed (2: No such file or directory)

执行

nginx -C /etc/nginx/nginx.cof

测试在10.20.20.8 上连接mysql 通过连接10.20.20.3来连接到主数据库 06上

mysql -udeng -h10.20.20.3 -p123456

修改8 9 上面nginx 配置文件访问网页的目录改为PHp路径

访问ip 测试数据库连接 10.20.20.8

wordpress目录下放置图片的位置

/wp-content/uploads

（nginx） 10.20.20.3

修改配置文件

实现负载均衡

把wordpress1 上面web目录下的文件拷贝到wordpress2 下面

或者重新在2的上面配置wordpress 和1 的上面要一样

server {

server_name www.dbbdbb.net;

listen 80;

location / {

root /code/wordpress;

index index.php index.html;

}

location ~ \.php$ {

root /code/wordpress;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

在wordpress2 上面要和wordpress1 上面nginx配置文件一样

的代码

server {

server_name www.dbbdbb.net;

listen 80;

location / {

root /code/wordpress;

index index.php index.html;

}

location ~ \.php$ {

root /code/wordpress;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

访问wordpress2 的ip 查看wordpress 网站是否和1 的一样

把监听ip改成域名

1的

2 的

做nfs

在3 上安装nfs

yum install nfs-utils -y

做目录共享

mkdir /nfsdata/images -pv

vim /etc/exports

systemctl restart nfs

在wordpress1 和2 上安装nfs-utils

yum install nfs-utils -y

wordoress1 上查看挂载的目录

showmount -e 10.20.20.3

如果目录下有数据就拷走等挂载完再考回来

mount -t nfs10.20.20.3:/nfsdata/images /data/nginx/wordpress/wp-content/iploads

2 的上面也挂载一下

并且写入文件中

vim /etc/fstab

或者写入

vim /etc/rc.d/rc.local

在3 上加负载

yum install haproxy

/etc/nginx/conf/conf.d/*.cong:

vim conf.d/blog.conf

加人 ip_hash: 服务请求只在一个服务器上

nfs的主从同步

3 上的主 4上的从

安装

yum install nfs-utils -y

从上要有和主上一样的目录结构

mkdir /nfsdata/images -pv

vim /etc/exports

systemctl start nfs

将主的数据拷贝到从上面

scp 10.20.20.3:/nfsdata/images/* 10.20.20.8:/nfsdata/images/

可以在8上执行拷贝命令也可以在别的主机上执行跨主机执行

做好秘钥认证

可以使用rsync 比scp好效验功能已有的文件不会拷贝

yum install rsync

rsync -avrlopg /nfsdata/images/* 10.20.30.8:/nfsdata/images/

秘钥认证

ssh-keygen

ssh-copy-id 10.20.20.4

yum install httpd-tools -y

攻击网站发起请求

查看本机的 ulimit -n

wordpress 更新

3 上面

把新版本的传进来

解包 tar xvf

cd wordpress

把wordpress1(10.20.20.3) 上面的配置文件拷贝到 3 上面

目录下

scp wp-config-php 10.20.20.3:/usr/local/src/wordpress

3 上

在wordpress目录下

配置文件

wp-config-php

修改配置

拷贝到wordpress2 下面

scp -r ./* 10.20.20.9:/data/nginx/wordpress

修改权限

chown www.www -R /data/nginx/wordpress/

过程

1 停止服务nginx

2备份原数据或删除

3 升级版本

4 启动服务nginx

解完包进入目录wordpress

打包 zip -r wordpress.zip wordpress/*

脚本

vim updata.sh

#!/bin/bash

ssh 10.20.20.8 “/usr/local/nginx/sbin/nginx -s stop”

ssh 10.20.20.8 “rm -rf /data/nginx/wordpress/*”

scp wordpress.zip 10.20.20.8:/data

ssh 10.20.20.8 “unzip /data/wordpress.zip -d /data/nginx/wordpress/ && /usr/local/nginx/sbin/nginx && chown www.www -R /data/nginx/wordpress/”

学会查看网页的调试器右键查看元素

总结配置文件

wordpress1 的配置文件

wordpress2 的一样

server {

server_name www.dbbdbb.net;

listen 80;

location / {

root /code/wordpress;

index index.php index.html;

}

location ~ \.php$ {

root /code/wordpress;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

nginx配置文件

stream {

upstream mysql {

server 10.20.20.6:3306;

}

server {

listen 10.20.20.16:3306;

proxy_pass mysql;

}

server {

listen 80;

server_name blogs;

index index.html index.php;

location / {

proxy_pass http://blogs;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_next_upstream http_502 http_504 error timeout invalid_header;

}

# vim /etc/nginx/conf.d/blog.conf

upstream blogs {

server 172.20.101.204:80 weight=1 max_fails=3 fail_timeout=100s;

server 172.20.101.205:80 weight=1 max_fails=3 fail_timeout=100s;

ip_hash;

}

server {

listen 80;

server_name www.dengbingbings.com;

index index.html index.php;

location / {

proxy_pass http://blogs;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_next_upstream http_502 http_504 error timeout invalid_header;

}

server_name www.dbbdbb.com 3台机必须一样

10.20.20.3 配置文件终极版

只需要这一个配置

#调配mysql数据库的

stream {

upstream mysql {

server 10.20.20.5:3306;

}

server {

listen 10.20.20.3:3306;

proxy_pass mysql;

}

#负载均衡wordpress

注释掉哈希是为了体现出轮询

upstream blogs {

server 172.20.101.204;

server 172.20.101.205;

# ip_hash;

# hash $request_uri consistent;

server {

listen 80;

location / {

proxy_pass http://blogs;

}

补充实验过程可以切换绑定域名的ip地址来查看实验的效果

C:\Windows\System32\Drivers\etc

wordpress1和2 的配置文件

[root@wordpress2 etc]#cat /etc/nginx/nginx.conf

user www;

worker_processes auto;

error_log /var/log/nginx/error.log warn;

如果要实现在一个wordpress上面添加图片另一个没有添加图片

访问可以看到图片和看不到图片，要修改wordpress后台的

WordPress地址（URL）和站点地址（URL）

修改为nginx的调度服务器的地址然后这个地址绑定到域名上

可能会出现的问题

修改完以后会因为密码不对进不去wordpress页面

解决办法

1 重新安装wordpress使俩个上面的配置都一样

复制拷贝过去

实验过程

在安装完一个wordpress以后在页面创建了以后再把wordpress的配置文件传到第二个上面
