nginx負載均衡如何部署雙機熱備方法及步驟

下文給大家帶來nginx負載均衡如何部署雙機熱備方法及步驟，希望能夠給大家在實際運用中帶來一定的幫助，負載均衡涉及的東西比較多，理論也不多，網上有很多書籍，今天我們就用億速云在行業內累計的經驗來做一個解答。

部署

ip分配 nginx192.168.1.5主機  192.168.1.6備機  浮動ip192.168.1.7

首先設置浮動ip（主備機器都要設置）

打開網卡eth0 配置好網絡參數

復制eth0為eth0:1

修改vim eth0:1 

NAME = eth0:1

DEVICE = eth0:1

IPADDR = 192.168.1.7

開啟轉發

echo "1" > /proc/sys/net/ipv4/ip_forward

修改/etc/sysctl.conf文件，讓包轉發功能在系統啟動時自動生效:

# Controls IP packet forwarding

net.ipv4.ip_forward = 1

重啟網絡

service network restart

安裝keepalived

yum install keepalived -y

修改配置文件

vim /etc/keepalived/keepalived.conf

主機配置情況

global_defs {

    notification_email { 

        #baojing@163.com  設置報警

        }

    router_id LVS_DEVEL

    }

    vrrp_script chk_http_port {

        script "</dev/tcp/127.0.0.1/8087"

        interval 1

        weight -10

    }

    vrrp_instance VI_1 {

        state MASTER

        interface eth0

        virtual_router_id 51

        priority 100

        advert_int 1

        authentication {

        auth_type PASS

        auth_pass 1111

    }

    virtual_ipaddress {

    192.168.1.7

    }

    track_script {

        chk_http_port

    }

    }

備用機上面配置

global_defs {

    notification_email { 

        #baojing@163.com  設置報警

        }

    router_id LVS_DEVEL

    }

    vrrp_script chk_http_port {

        script "</dev/tcp/127.0.0.1/8087"

        interval 1

        weight -10

    }

    vrrp_instance VI_1 {

        state BACKUP

        interface eth0

        virtual_router_id 51

        priority 90

        advert_int 1

        authentication {

        auth_type PASS

        auth_pass 1111

    }

    virtual_ipaddress {

    192.168.1.7

    }

    track_script {

        chk_http_port

    }

    }

啟動查看keepalived情況

killall keepalived

service keepalived start

tail -f /var/log/messages

安裝nginx配置轉發負載均衡

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

添加負載均衡配置

       upstream mytest {

                #least_conn;

                #ip_hash;  

            server 1.test.com weight=3 max_fails=2 fail_timeout=30s;

            server 2.test.com weight=3 max_fails=2 fail_timeout=30s;

            server 3.test.com weight=5 max_fails=3 fail_timeout=30s;

                    }

        location ^~/piwik/ {

            proxy_pass http://mytest;

            }

/usr/local/nginx/sbin/nginx -t

/usr/local/nginx/sbin/nginx 

/usr/local/nginx/sbin/nginx -s reload        重新加載配置
