nginx部署wordpress架構

實驗環境

（nginx） 10.20.20.3

（WordPress nginx PHP） 10.20.20.4 10.20.20.5

（mysql 主從） 10.20.20.6 10.20.20.7

查看Word

Press支持的mysql版本

數據庫主從設置

安裝依賴包

yum install libaio* -y

官網下載包二進制安裝

腳本安裝 #腳本練習我QQ 790827253

傳入包安裝mysql

10.20.20.6 （主） 10.20.20.7（從）

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

建立庫用戶

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';

若是主數據庫以前有數據要把數據導出來而後讓從數據庫同步

要把日誌改爲數據大的時候

導出文件

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

傳入從

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

/etc/init.d/mysqld restart

查看二進制日誌

從配置

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 導入sql文件數據

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;

驗證

show databases;

start slave ；

show slave status\G

主從複製的問題

1 防火牆是否關閉

2 日誌必定要同步到正確的時候

3 使用reset slave 清除同步信息 reset maser

pm.start_servers #，啓動時的進程數
pm.min_spare_servers #，保證空閒進程數最小值，若是空閒進程小於此值，則建立新的子進程
pm.max_spare_servers #，保證空閒進程數最大值，若是空閒進程大於此值，此進行清理

啓動

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

（WordPress nginx）10.20.20.4 10.20.20.5

安裝nginx

配置官方yum源

或者編譯安裝

倆個服務器都是同樣的配置

編譯安裝過程

cd /usr/local/scr/

傳入安裝包 1.12

解壓縮

tar xvf

cd 進去編譯

./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：建立php測試頁：

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

<?php

phpinfo();

1.6：準備數據庫：

mysql> CREATE DATABASE wordpress;

建立的用戶是負載均衡的ip地址這裏是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 #修改數據庫配置

# grep "^[a-Z]" wp-config.php

wp-config.php 文件中的主機不是mysql的地址而是負載均衡的nginxip 10.20.20.3 獨立的

訪問網站獲得的替換在下面

測試並啓動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

部署博客產品Wordpress

1) 配置Nginx虛擬主機站點，域名爲 www.dbb.com

#1.nginx具體配置信息

[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) 重啓nginx服務

[root@nginx ~]# systemctl restart nginx

3) 獲取wordpress產品，解壓並部署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 文件中的主機不是mysql的地址而是負載均衡的nginxip 10.20.20.3 獨立的

4) 因爲wordpress產品須要依賴數據庫, 因此須要手動創建數據庫

[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負載均衡

一樣安裝nginx

安裝mysql

鏈接主mysql的服務器

mysql -udeng -h10.20.20.6 -p123456

配置負載均衡

vim /etc/nginx/nginx.cof

stream {

upstream mysql {

server 10.20.20.6:3306;

}

server {

listen 10.20.20.3 :3306;

proxy_pass mysql;

}

啓動nginx

nginx -t

nginx -s reload

端口是否打開

若是nginx啓動錯誤

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

執行

nginx -C /etc/nginx/nginx.cof

測試在10.20.20.8 上鏈接mysql 經過鏈接10.20.20.3來鏈接到主數據庫 06上

mysql -udeng -h10.20.20.3 -p123456

修改8 9 上面nginx 配置文件訪問網頁的目錄改成PHp路徑

訪問ip 測試數據庫鏈接 10.20.20.8

wordpress目錄下放置圖片的位置

/wp-content/uploads

（nginx） 10.20.20.3

修改配置文件

實現負載均衡

把wordpress1 上面web目錄下的文件拷貝到wordpress2 下面

或者從新在2的上面配置wordpress 和1 的上面要同樣

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配置文件同樣

的代碼

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;

}

訪問wordpress2 的ip 查看wordpress 網站是否和1 的同樣

把監聽ip改爲域名

1的

2 的

作nfs

在3 上安裝nfs

yum install nfs-utils -y

作目錄共享

mkdir /nfsdata/images -pv

vim /etc/exports

systemctl restart nfs

在wordpress1 和2 上安裝nfs-utils

yum install nfs-utils -y

wordoress1 上查看掛載的目錄

showmount -e 10.20.20.3

若是目錄下有數據就拷走等掛載完再考回來

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

2 的上面也掛載一下

而且寫入文件中

vim /etc/fstab

或者寫入

vim /etc/rc.d/rc.local

在3 上加負載

yum install haproxy

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

vim conf.d/blog.conf

加人 ip_hash: 服務請求只在一個服務器上

nfs的主從同步

3 上的主 4上的從

安裝

yum install nfs-utils -y

從上要有和主上同樣的目錄結構

mkdir /nfsdata/images -pv

vim /etc/exports

systemctl start nfs

將主的數據拷貝到從上面

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

能夠在8上執行拷貝命令也能夠在別的主機上執行跨主機執行

作好祕鑰認證

可使用rsync 比scp好效驗功能已有的文件不會拷貝

yum install rsync

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

祕鑰認證

ssh-keygen

ssh-copy-id 10.20.20.4

yum install httpd-tools -y

攻擊網站發起請求

查看本機的 ulimit -n

wordpress 更新

3 上面

把新版本的傳進來

解包 tar xvf

cd wordpress

把wordpress1(10.20.20.3) 上面的配置文件拷貝到 3 上面

目錄下

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

3 上

在wordpress目錄下

配置文件

wp-config-php

修改配置

拷貝到wordpress2 下面

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

修改權限

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

過程

1 中止服務nginx

2備份原數據或刪除

3 升級版本

4 啓動服務nginx

解完包進入目錄wordpress

打包 zip -r wordpress.zip wordpress/*

腳本

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/"

學會查看網頁的調試器右鍵查看元素

}

server_name www.dbbdbb.com 3臺機必須同樣

10.20.20.3 配置文件終極版

只須要這一個配置

#調配mysql數據庫的

stream {

upstream mysql {

server 10.20.20.5:3306;

}

server {

listen 10.20.20.3:3306;

proxy_pass mysql;

}

#負載均衡wordpress

註釋掉哈希是爲了體現出輪詢

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;

}

若是要實如今一個wordpress上面添加圖片另外一個沒有添加圖片

訪問能夠看到圖片和看不到圖片，要修改wordpress後臺的

WordPress地址（URL）和站點地址（URL）

修改成nginx的調度服務器的地址而後這個地址綁定到域名上

可能會出現的問題

修改完之後會由於密碼不對進不去wordpress頁面

解決辦法

1 從新安裝wordpress使倆個上面的配置都同樣

複製拷貝過去

實驗過程

在安裝完一個wordpress之後在頁面建立了之後再把wordpress的配置文件傳到第二個上面
