機器規划和架構圖
部署nginx負載均衡
配置nginx負載
安裝nginx服務
[root@linux-node4 ~]# yum -y install nginx
配置反向代理
[root@lb-master ~]# vim /etc/nginx/nginx.conf stream { log_format main '$remote_addr $upstream_addr - [$time_local] $status $upstream_bytes_sent'; access_log /var/log/nginx/django-access.log main; upstream django-apiserver { server 192.168.56.62:80; server 192.168.56.63:80; } server { listen 88; proxy_pass django-apiserver; } }
完整配置如下
看一下即可，都是nginx默認配置
http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; \#tcp_nopush on; keepalive_timeout 65; \#gzip on; include /etc/nginx/conf.d/*.conf; }
測試反向代理可用性
[root@lb-master ~]# vim /etc/keepalived/keepalived.conf global_defs { notification_email { acassen@firewall.loc failover@firewall.loc sysadmin@firewall.loc } notification_email_from Alexandre.Cassen@firewall.loc smtp_server 127.0.0.1 smtp_connect_timeout 30 router_id NGINX_MASTER } \# 健康監測nginx vrrp_script check_nginx { script "/etc/keepalived/check_nginx.sh" # 設置檢查nginx是否存活的腳本位置 } \# keepalive熱備組配置 vrrp_instance VI_1 { state MASTER # 配置當前keepalive為master角色 interface eth0 # 網卡名字，必須和實際網卡名稱一致，默認是ens33 virtual_router_id 51 # VRRP 路由 ID實例，每個實例是唯一的 priority 100 # 優先級，備服務器設置 90 advert_int 1 # 指定VRRP 心跳包通告間隔時間，默認1秒 authentication { auth_type PASS auth_pass 1111 # 設置keepalive的master和slave之間簡單的秘鑰認證 } virtual_ipaddress { 192.168.56.60/24 # 設置keepalive虛擬IP地址 } track_script { check_nginx } }
