centos7 lnmp分離部署及均衡

一、環境

二、流程（思路）

1、先安裝LNMP（192.168.1.22+192.168.1.24+122.51.223.193），安裝wordpress
2、配置nginx負載均衡
3、添加php均衡
4、配置mariadb主從

三、安裝lnmp及wordpress

1、安裝nginx（192.168.1.22）

1)、Nginx安裝

Nginx這裏使用阿里的epel源直接yum安裝

[root@localhost ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
[root@localhost ~]# yum clean all
[root@localhost ~]# yum makecache
[root@localhost ~]# yum install –y nginx-1.16.1  安裝nginx-1.16.1版本

下載wordpress並放至項目目錄

[root@localhost src]# wget -c https://wordpress.org/latest.tar.gz -O /usr/share/nginx/html/wordpress.tar.gz
[root@localhost src]# cd /usr/share/nginx/html/
[root@localhost html]# tar xf wordpress.tar.gz
[root@localhost html]# chown -R nginx:nginx wordpress

2)、配置

vim /etc/nginx/nginx.conf

[root@localhost html]# vim /etc/nginx/nginx.conf
        location / {
                root         /usr/share/nginx/html/wordpress;
                index   index.php;
        }

        location ~ \.php$ {
               root           /data/nginx/html/wordpress/;  PHP的目錄
               fastcgi_pass   192.168.1.24:9000;
               fastcgi_index  index.php;
               fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
               include        fastcgi_params;
        }

2、安裝PHP（192.168.1.24）

1）、更換清華源，安裝php5.6,默認是5.4

[root@localhost ~]# yum install https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/remi-release-7.rpm
[root@localhost yum.repos.d]# vim remi.repo
30 enabled=1

安裝php

[root@localhost ~]# yum install php php-fpm php-mysql php-devel php-xml –y

配置php-fpm用戶組

[root@localhost ~]# vim /etc/php-fpm.d/www.conf
user = nginx
group = nginx
listen = 192.168.1.24:9000
;listen.allowed_clients =	這裏指的是nginx服務的IP，這裏將他註釋
[root@localhost ~]# chown -R nginx:nginx /var/lib/php/session/
[root@localhost ~]# mkdir -p /data/nginx/html		PHP的目錄
[root@localhost ~]# chown -R nginx:nginx /data/nginx/html/	PHP的目錄

項目同步，將nginx的項目目錄同步到PHP的目錄中，包含權限

[root@localhost ~]# rsync -av [email protected]:/usr/share/nginx/html/wordpress /data/nginx/html/

關閉selinux，開啓9000端口後訪問瀏覽器

3、安裝mariadb(122.51.223.193)

安裝

[root@VM_0_14_centos ~]# yum install mariadb mariadb-devel mariadb-server mariadb-libs –y
[root@VM_0_14_centos ~]# systemctl start  mariadb

對PHP授權

[root@VM_0_14_centos ~]# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 2
Server version: 5.5.65-MariaDB MariaDB Server

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> create database wordpress charset utf8;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> grant all on wordpress.* to "wordpress"@"%" identified by "123456";
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.01 sec)
注：這裏是公網對內網授權，所以寫的是"%"

4、瀏覽器安裝wrodpress

注：如果有頁面排版亂碼的現象，需要反同步一下nginx的項目目錄
Php端
[root@localhost html]# rsync -av /data/nginx/html/wordpress/ [email protected]:/usr/share/nginx/html/wordpress/

四、安裝配置nginx集羣

1、配置

Nginx1:192.168.1.22服務器
[root@localhost ~]# vim /etc/nginx/nginx.conf

server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        #server_name  _;
        root         /usr/share/nginx/html/wordpress;
        index    index.php;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
                root         /usr/share/nginx/html/wordpress;
                index   index.php;
        }

        location ~ \.php$ {
               root           /data/nginx/html/wordpress/;
               fastcgi_pass   192.168.1.24:9000;
               fastcgi_index  index.php;
               fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
               include        fastcgi_params;
        }

Nginx1:192.168.1.23服務器同上
Nginx1:192.168.1.21均衡服務器
[root@localhost ~]# vim /etc/nginx/nginx.conf

[root@localhost ~]# vim /etc/nginx/nginx.conf   注：這裏upstream塊與server平級，都在http塊中
               upstream web {
                ip_hash;
                server 192.168.1.22 weight=1;
                server 192.168.1.23 weight=1;
               }
        server {
                listen 80;
                server_name blog.yjy.com;

                location /{
                        proxy_pass http://web;
                        proxy_next_upstream error http_404 http_502;
                 }
        }

瀏覽器訪問

此時，停止任意一臺nginx服務器，都不影響客戶使用

五、配置php-fpm均衡

Php-fpm2 192.168.1.25配置

[root@localhost ~]# vim /etc/php-fpm.d/www.conf
user = nginx
group = nginx
listen = 192.168.1.24:9000
#listen.allowed_clients =	這裏指的是nginx服務的IP，這裏將他註釋
[root@localhost ~]# chown -R nginx:nginx /var/lib/php/session/
[root@localhost ~]# mkdir -p /data/nginx/html		PHP的目錄
[root@localhost ~]# chown -R nginx:nginx /data/nginx/html/	PHP的目錄

其他安裝步驟一樣，直接同步動態目錄

[root@localhost ~]# rsync -av [email protected]:/data/nginx/html/ /data/nginx/html/

nginx1(192.168.1.22)及nginx2(192.168.1.23)上面配置php-fpm均衡

[root@localhost ~]# vim /etc/nginx/nginx.conf
        upstream cgi_wordpress{
                server 192.168.1.24:9000;
                server  192.168.1.25:9000;
                }

        location ~ \.php$ {
               root           /data/nginx/html/wordpress/;
               fastcgi_pass   cgi_wordpress;
               fastcgi_index  index.php;
               fastcgi_next_upstream error;		增加此行
               fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
               include        fastcgi_params;
        }

測試php均衡，停止192.168.1.24上面的PHP-fpm，看是否可以繼續訪問網頁

六、配置主從

1、配置my.cnf

Mariadb master（122.51.223.193）配置

[root@VM_0_14_centos ~]# vim /etc/my.cnf
[mysqld]
log-bin=mariadb-bin
server-id=1

mariadb slave(60.165.98.10)配置

[root@instance-plpaum9p ~]# vim /etc/my.cnf
[mysqld]
server-id=2

2、啓動mariadb

[root@VM_0_14_centos ~]# systemctl restart mariadb	   master
[root@instance-plpaum9p ~]# systemctl restart mariadb		slave

3、主庫wordpress數據導出且記錄bin文件與pos點

[root@VM_0_14_centos ~]# mysqldump -B --master-data wordpress >wordpress.sql

[root@VM_0_14_centos ~]# less wordpress.sql

4、主庫授權

MariaDB [(none)]> grant replication slave on *.* to "tongbu"@"182.61.46.116" identified by "123456";         
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;    
Query OK, 0 rows affected (0.00 sec)

5、從庫

新建wordpress數據庫
MariaDB [(none)]> create database wordpress charset utf8;
數據導入
[root@instance-plpaum9p ~]# mysql <wordpress.sql
連接主庫
MariaDB [(none)]> change master to master_host="122.51.223.193",
    -> master_user="tongbu",
    -> master_password="123456",
    -> master_log_file="mariadb-bin.000001",
    -> master_log_pos=245;
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> slave start;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> show slave status\G 
*************************** 1. row ***************************
               Slave_IO_State: Waiting for master to send event
                  Master_Host: 122.51.223.193

  Replicate_Ignore_Server_Ids: 
             Master_Server_Id: 1
1 row in set (0.00 sec)

6、主從測試

在wordpress中新建用戶，在從庫中查

測試OK

注：主從同步時，如果只同步一個數據庫，
1、在主的my.cnf中加上一句binlog-do-db=wrodpress，見下
[mysqld]
log-bin=mariadb-bin
server-id=1
binlog-do-db=wrodpress
2、主庫授權時，不用另說明授權庫
3、從庫change master時，不用添加同步數據庫的說明
