Keepalived+nginx+rabbitmq实现高可用负载均衡

时间：2019-01-16 09:38:50

环境搭建:

略

NGINX配置:

因为我用的是windows环境配置的docker导致无法从主机直接ping容器,所以Nginx使用的是Multipass虚拟机.

搭建好ubuntu环境,NginxMS,NginxS1

PS C:\Users\****> multipass.exe lsNameState IPv4 Imageprimary Deleted --Not AvailablenginxMS Running 172.23.249.108 Ubuntu 22.04 LTSnginxS1 Running 172.23.253.212 Ubuntu 22.04 LTS

nginx.conf 主机和从机

user www-data;worker_processes auto;pid /run/nginx.pid;include /etc/nginx/modules-enabled/*.conf;events {worker_connections 768;# multi_accept on;}stream {upstream rabbitmqserver {server 192.168.0.106:5672;server 192.168.0.106:5673;server 192.168.0.106:5674;}server {listen 5670;proxy_pass rabbitmqserver;}}http {### Basic Settings##sendfile on;tcp_nopush on;types_hash_max_size 2048;# server_tokens off;# server_names_hash_bucket_size 64;# server_name_in_redirect off;include /etc/nginx/mime.types;default_type application/octet-stream;### SSL Settings##ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLEssl_prefer_server_ciphers on;### Logging Settings##access_log /var/log/nginx/access.log;error_log /var/log/nginx/error.log;### Gzip Settings##gzip on;# gzip_vary on;# gzip_proxied any;# gzip_comp_level 6;# gzip_buffers 16 8k;# gzip_http_version 1.1;# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;upstream rabbitManage {server 192.168.0.106:15672;server 192.168.0.106:15673;server 192.168.0.106:15674;}server {listen 15675;server_name 172.23.253.200;location / {proxy_pass http://rabbitManage;index index.html index.htm;}}### Virtual Host Configs##include /etc/nginx/conf.d/*.conf;include /etc/nginx/sites-enabled/*;}#mail {# # See sample authentication script at:# # /ImapAuthenticateWithApachePhpScript## # auth_http localhost/auth.php;# # pop3_capabilities "TOP" "USER";# # imap_capabilities "IMAP4rev1" "UIDPLUS";## server {#listenlocalhost:110;#protocol pop3;#proxyon;# }## server {#listenlocalhost:143;#protocol imap;#proxyon;# }#}

KEEPALIVED配置:

在上面安装好Nginx的虚拟机中安装Keepalived

KeepAlived(MASTER):

! Configuration File for keepalivedglobal_defs {router_id HA-M1}vrrp_script chk_nginx {script "/etc/keepalived/nginx_check.sh"interval 2fall 3rise 2}vrrp_instance VI_MYSQL {state MASTERinterface eth0virtual_router_id 100priority 100advert_int 1authentication {auth_type PASSauth_pass 1111}virtual_ipaddress {172.23.253.200 dev eth0 label eth0:vip}track_script {chk_nginx}}

KeepAlived(SALVE):

!

nginx_check Nginx存活检查文件:

#!/bin/bashA=`ps -C nginx --no-header |wc -l`if [ $A -eq 0 ]thenecho 'nginx server is died'sudo killall keepalivedfi

RABBITMQ集群搭建:

三台docker容器用命令加入集群具体命令百度吧我用的时候我也百度

但是docker run命令一定要用link连接

docker run -d --hostname rabbitMS --name mqMS -p 5672:5672 -p 15672:15672 -e RABBITMQ_ERLANG_COOKIE="rabbitmq_cookie" rabbitmq:3.11-managementdocker run -d --hostname rabbitS1 --name mqS1 --link mqMS:link01 -p 5673:5672 -p 15673:15672 -e RABBITMQ_ERLANG_COOKIE="rabbitmq_cookie" rabbitmq:3.11-managementdocker run -d --hostname rabbitS2 --name mqS2 --link mqMS:link02 --link mqS1:link03 -p 5674:5672 -p 15674:15672 -e RABBITMQ_ERLANG_COOKIE="rabbitmq_cookie" rabbitmq:3.11-management
