Based on keepalived implementation, the Nginx and PHP-FPM services in two Realserver servers are mainly from

Idea: Using two VIP, a positioning nginx, a positioning php-fpm

Steps:

1 , prepare two sets based on Lnmp architected servers (capable of providing normal Web services)

2, in Nginx main php-fpm for the preparation of the machine operation:

① Editing the keepalived configuration file (refer to the blog for specific meanings of the contents of the document:

http://13150617.blog.51cto.com/13140617/1979652)

Vim/etc/keepalived/keepalived.conf

! Configuration File for Keepalived

Global_defs {

Notification_email {

[Email protected]

}

Notification_email_from [email protected]

Smtp_server 127.0.0.1

Smtp_connect_timeout 2

router_id Lvs_develhaha

}

Vrrp_instance Vi_1 {

State MASTER

Interface eth0

virtual_router_id 11

Priority 100

Advert_int 1

Authentication {

Auth_type PASS

Auth_pass 111111

}

virtual_ipaddress {

172.17.0.22

}

}

Vrrp_instance Vi_2 {

State BACKUP

Interface eth1

virtual_router_id 12

Priority 90

Advert_int 1

Authentication {

Auth_type PASS

Auth_pass 111111

}

virtual_ipaddress {

192.168.199.33

}

}

② configures the PHP-FPM so that it listens on port 9000 and allows all hosts to access

Vim/etc/php-fpm.d/www.conf

Listen = 9000

Note Listen.allowed_clients = any

③ configure Nginx to point to the host on which PHP resides

Vim/etc/nginx/nginx.conf

Fastcgi_pass 192.168.199.33:9000; Virtual IP

④ Turn on forwarding function

Echo 1 >/proc/sys/net/ipv4/ip_forward

⑤ Start Service

Systemctl Start KeepAlive

3, PHP-FPM main nginx for the preparation of the machine operation:

① editing the keepalived configuration file

Vim/etc/keepalived/keepalived.conf

With the above configuration, only the state and priority priorities need to be swapped

② Configuration php-fpm

Vim/etc/php-fpm.d/www.conf

Configuration completely ibid.

③ configuration Nginx

Vim/etc/nginx/nginx.conf

Configuration completely ibid.

④ Turn on forwarding function

Echo 1 >/proc/sys/net/ipv4/ip_forward

⑤ Start Service:

Systemctl Start KeepAlive

4, testing: Two servers are normal service, Nginx-based machine and PHP-FPM-based machines have a VIP, the site can be visited normally

When a server fails, the VIP will drift to the normal server, and the site will still be accessible
