搭建服务

搭建该服务的所需环境

实现思路

搭建步骤

一、搭建LNMP-All in One

二、分离部署LNMP

三、分离LNMP部署完成后，将两组LNMP的MySQL设置为主主关系

四、Nginx负载均衡配置

五、DNS

六、客户端访问

搭建服务

搭建该服务的所需环境

1.先行搭建LNMP-All in One

（IP：188.188.188.180）

2.搭建分离LNMP

（php-IP：188.188.188.188；nginx-ip：188.188.188.189；mysql-ip：188.188.188.190）

3.搭建两台静态apache服务器

（apache-1-IP：172.169.25.253；apache-2-IP：172.169.25.254）

4.搭建Nginx负载均衡，配置文件设置IP不可访问，动态为两组LNMP，静态为俩组apache。与三个网段建立连接

（Nginx-IP-1：192.168.1.2 、Nginx-IP-2：188.188.188.250、Nginx-IP-3：172.169.25.250）

5.DNS服务配置正向解析

（DNS-IP-1：192.168.1.10）

6.客户端访问

（IP：192.168.1.20）

实现思路

1.在搭建好所有环境之后，将两组LNMP放在同一个网段中(188.188.188.0)，配置页面全部无误，放行端口，相互访问无误。

它的作用是提供动态页面

2. 搭建两台apache服务器后(172.169.25.0)，配置静态页面内容。

它的作用是提供静态页面

3. 搭建Nginx负载均衡服务器后，设置三个网段，分别连接三种不同的服务，将这个服务配置与两种页面链接的内容，重启服务，放行端口后，进行访问，无误后进行下一步。

它的作用是在其他网段访问时，提供这两种不同网段的不同页面

4. 搭建DNS服务器，设置正向解析，本机使用域名访问，成功后便可使用客户端通过域名访问。

它的作用是将Nginx负载均衡的IP解析成为域名，使得客户端即使不使用IP便可访问到Nginx负载均衡服务器

搭建步骤

一、搭建LNMP-All in One

             include        fastcgi.conf;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one

# 找到并修改下方内容
[root@zjx-0703-LNMP ~]# vim /usr/local/php/etc/php-fpm.conf

......
user = nginx
group = nginx

......
listen = 188.188.188.180:9000

......

创建文件，并加入页面内容

[root@zjx-0703-LNMP ~]# mkdir /www
[root@zjx-0703-LNMP ~]# vim /www/index.php 
<?php
        echo "zhaha"
?>

访问

[root@zjx-0703-LNMP ~]# firefox 188.188.188.180/index.php

访问成功

制作与MySQL关联的PHP页面

[root@zjx-0703-LNMP ~]# mysql

修改页面，并访问

[root@zjx-0703-LNMP ~]# vim /www/index.php 
<?php
        $servername="188.188.188.180";
        $username="zzz";
        $password="123.com";
        $conn=mysqli_connect($servername,$username,$password);
        if(!$conn){
                die("cannot connect!!!");
        }
        echo "success connect-1";
?>

[root@zjx-0703-LNMP ~]# firefox 188.188.188.180/index.php

如果访问不成功重启服务

还是访问不到就重启PC，或者多次给MySQL授权

之后给php服务器安装扩展库mysqli

[root@zjx-0703-LNMP ~]# cd /usr/local/php/
[root@zjx-0703-LNMP php]# ln -s /usr/local/php/bin/phpize /usr/bin/
[root@zjx-0703-LNMP php]# cd /usr/src/php-5.3.28/ext/mysqli
[root@zjx-0703-LNMP mysqli]# phpize

[root@zjx-0703-LNMP mysqli]# make

[root@zjx-0703-LNMP mysqli]# make test

[root@zjx-0703-LNMP mysqli]# make install

[root@zjx-0703-LNMP mysqli]# vim /usr/local/php/php.ini 

/usr/local/php/php.ini 文件中加入以下内容

重启服务，并访问

[root@zjx-0703-LNMP mysqli]# systemctl restart php-fpm
[root@zjx-0703-LNMP mysqli]# nginx -s reload
[root@zjx-0703-LNMP mysqli]# firefox 188.188.188.180/index.php

放行服务

[root@zjx-0703-PHP ~]# firewall-cmd --add-service=msql
success
[root@zjx-0703-PHP ~]# firewall-cmd --add-service=mysql --permanent 
success

[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=9000/tcp
success
[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=9000/tcp --permanent 
success

[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=80/tcp
success
[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent 
success

[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=3306/tcp
success
[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent 
success

至此，整合的LNMP完成

二、分离部署LNMP

与整合LNMP操作相同

[root@zjx-0703-PHP php-5.3.28]# make && make install
[root@zjx-0703-PHP php-5.3.28]# cp php.ini-development /usr/local/php/php.ini
[root@zjx-0703-PHP php-5.3.28]# vim /usr/local/php/php.ini 

至此，三个基本环境安装完成

将三者整合建立连接

PHP与Nginx整合

进入PHP创建nfs共享目录，

[root@zjx-0703-PHP ~]# mkdir /www
[root@zjx-0703-PHP ~]# vim /etc/exports

在文件中插入下面内容

/www 188.188.188.0/24(sync,rw,no_root_squash)

检测

[root@zjx-0703-PHP php-5.3.x]# exportfs -rv
exporting 188.188.188.0/24:/www

重启服务，放行服务

[root@zjx-0703-PHP ~]# systemctl restart nfs
[root@zjx-0703-PHP ~]# systemctl restart rpcbind
[root@zjx-0703-PHP ~]# firewall-cmd --add-service=nfs
success
[root@zjx-0703-PHP ~]# firewall-cmd --add-service=nfs --permanent 
success
[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=9000/tcp
success
[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=9000/tcp --permanent 
success

在nginx中，创建共享文件目录/www，修改主配置文件与PHP服务器关联

[root@zjx-0703-Nginx ~]# mkdir /www
[root@zjx-0703-Nginx ~]# vim /usr/local/nginx/conf/nginx.conf
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
            root           /www;
            # 写入PHP的IP
            fastcgi_pass   188.188.188.188:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi.conf;
        }

        # deny access to .htaccess files, if Apache's document root
[root@zjx-0703-Nginx ~]# nginx -s reload

挂载共享目录

[root@zjx-0703-Nginx ~]# mount -t nfs 188.188.188.188:/www /www/
[root@zjx-0703-Nginx ~]# df -Th /www/
文件系统             类型  容量  已用  可用 已用% 挂载点
188.188.188.188:/www nfs4   17G  4.3G   13G   26% /www

搭建网页，并访问

[root@zjx-0703-Nginx ~]# vim /www/index.php
# 文件中加如下面内容
<?php
        echo "kkk"
?>
[root@zjx-0703-Nginx ~]# firefox 188.188.188.189/index.php

PHP与Nginx整合成功，访问成功

MySQL与php的整合

  MySQL授权用户

[root@zjx-0703-LNMP ~]# mysql 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5
Server version: 5.5.22 Source distribution

mysql> 	exit;

index.php文件修改内容

[root@zjx-0703-MySQL ~]# vim /www/index.php 
<?php
        $servername="188.188.188.190";
        $username="zzz";
        $password="123.com";
        $conn=mysqli_connect($servername,$username,$password);
        if(!$conn){
                die("cannot connect!!!");
        }
        echo "success connect";
?>

创建共享目录，并挂载

[root@zjx-0703-MySQL ~]# mkdir /www
[root@zjx-0703-MySQL ~]# mount -t nfs 188.188.188.188:/www /www/

放行服务

[root@zjx-0703-MySQL ~]# firewall-cmd --zone=public --add-port=3306/tcp
success
[root@zjx-0703-MySQL ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent 
success
[root@zjx-0703-MySQL ~]# firewall-cmd --add-service=mysql
success
[root@zjx-0703-MySQL ~]# firewall-cmd --add-service=mysql --permanent 
success

Nginx放行服务

[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=80/tcp
success
[root@zjx-0703-PHP ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent 
success

当在nginx中访问到success connect便说明成功

至此，第二组LNMP成功

三、分离LNMP部署完成后，将两组LNMP的MySQL设置为主主关系

两台的设置都相同，但是server-id不能相同

报错解决

主1

[root@zjx-0703-LNMP ~]# cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf
[root@zjx-0703-LNMP ~]# vim my.cnf
# binary logging is required for replication
log-bin=master-bin
log-slave-updata=true

# binary logging format - mixed recommended
binlog_format=mixed

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id       = 11

# Replication Slave (comment out master section to use this)

[root@zjx-0703-LNMP ~]# systemctl restart mysqld

主2

[root@zjx-0703-MySQL ~]# cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf
[root@zjx-0703-MySQL ~]# vim my.cnf
# binary logging is required for replication
log-bin=master-bin
log-slave-updata=true

# binary logging format - mixed recommended
binlog_format=mixed

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id       = 12

# Replication Slave (comment out master section to use this)

[root@zjx-0703-MySQL ~]# systemctl restart mysqld

配置MySQL-1时同时配置MySQL-2

MySQL-1配置

mysql> mysql> grant replication slave on *.*to'kms'@'188.188.188.% ' identified by'123.com';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.01 sec)

mysql> start slave;
Query OK, 0 rows affected (0.01 sec)

mysql> show slave status\G

四、Nginx负载均衡配置

[root@zjx-0703-Nginx-load ~]#  vim /usr/local/nginx/conf/nginx.conf
    #gzip  on;
    #静态页面访问地址
     upstream zzz{
        # 服务器地址，页面IP:端口  工作优先级  最大失败次数  连接超时时间
             server 172.169.25.253:80 weight=2 max_fails=2 fail_timeout=30s;
             server 172.169.25.254:80 weight=3 max_fails=2 fail_timeout=30s;
     }
     动态页面访问地址
    upstream kkk{
        server 188.188.188.180:80 weight=2 max_fails=2 fail_timeout=30s;
        server 188.188.188.189:80 weight=2 max_fails=2 fail_timeout=30s;
    }
    server {
        listen       80;

        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}
        # 静态页面访问配置
        location ~*\.(html|gif|png|jpeg|jpg) {
                  proxy_pass      http://zzz;
        }
        # 动态页面访问配置
        location ~ \.php$ {
            proxy_pass  http://kkk;
            proxy_redirect  off;
            proxy_set_header  Host  $host;
            proxy_set_header  X_Real_IP  $remote_addr;
            proxy_set_header  X_Forward_For  $proxy_add_x_forwarded_for;
        }
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #

nginx -s reload

进入IP地址配置文件，将IP获取方式改为static，之后在下面加入改内容

IPADDR0=192.168.1.2
NETMASK0=255.255.255.0
IPADDR1=188.188.188.250
NETMASK1=255.255.255.0
IPADDR2=172.169.25.250
NETMASK=255.255.255.0

[root@zjx-0703-Nginx-load ~]#  ip addr 
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:3f:27:ac brd ff:ff:ff:ff:ff:ff
    inet 172.169.25.250/16 brd 172.169.255.255 scope global ens33
       valid_lft forever preferred_lft forever
    inet 188.188.188.250/24 brd 188.188.188.255 scope global ens33
       valid_lft forever preferred_lft forever
    inet 192.168.1.2/24 brd 192.168.1.255 scope global ens33
       valid_lft forever preferred_lft forever
    inet6 fe80::b3e1:947a:855d:f4cf/64 scope link 
       valid_lft forever preferred_lft forever

与以他两个服务器ping通之后就OK了

五、DNS

[root@zjx-0703-DNS ~]#  yum -y install bind
[root@zjx-0703-DNS ~]# vim /etc/*/*/*ens33
[root@zjx-0703-DNS ~]# systemctl restart network
[root@zjx-0703-DNS ~]# vim /etc/named.conf 

[root@zjx-0703-DNS ~]# cd /var/named/
[root@zjx-0703-DNS named]#  cp -p named.localhost proncomix.zone
[root@zjx-0703-DNS named]#  vim /etc/named.rfc1912.zones 
[root@zjx-0703-DNS named]#  vim proncomix.zone 
[root@zjx-0703-DNS named]#  systemctl restart named

# named.rfc1912.zones在该配置文件文末添加以下内容
[root@zjx-0703-DNS ~]# vim /etc/named.rfc1912.zones 
zone "proncomix.com" IN {
        type master;
        file "proncomix.zone";
};

/etc/named.conf在该配置文件文末添加以下内容

options {
        listen-on port 53 { any; };
        listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { any; };

修改正向解析数据文件

[root@zjx-0703-DNS ~]# vim /var/named/proncomix.zone 
$TTL 1D
@       IN SOA  proncomix.com. root.proncomix.com. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      @
        A       192.168.1.2
        AAAA    ::1
www     A       192.168.1.2

[root@zjx-0703-DNS ~]# vim /etc/hosts
192.168.1.2 www.proncomix.com

六、客户端访问

重启服务后，用客户端访问

在客户端上指定一下DNS

客户端IP—192.168.1.20

[root@zjx-0703-client ~]# vim /etc/resolv.conf 
nameserver 192.168.1.10

访问即可

# 访问静态
[root@zjx-0703-client ~]# firefox www.proncomix.com/

刷新页面时，出现两个不同页面，访问成功

# 访问动态数据库
[root@zjx-0703-client ~]# firefox www.proncomix.com/index.php

当使用IP访问Nginx是，发现能访问成功

所以到Nginx主配置文件添加内容

[root@zjx-0703-Nginx-load ~]#  vim /usr/local/nginx/conf/nginx.conf
# 添加一个server,设置为使用IP访问便报错404
server {
	listen 80 default;
	return 404;
}

客户端在试着访问

至此，实验完成
