cloudstack management高可用

一、环境说明

CPU： kunpeng 920
操作系统：OpenEuler 22.03

IP	角色
192.168.157.20	mysql
192.168.157.21	management-server 1
192.168.157.22	management-server 2
192.168.157.30	nginx

二、部署

基础环境准备参考【cloudstack测试环境搭建】

1、部署mysql（测试环境，生产环境请自行调整细节）

#安装
yum install mysql mysql-server
vim /etc/my.cnf
server-id=1
innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=350
log-bin=mysql-bin
binlog-format = 'ROW'
systemctl start mysqld
systemctl enable mysqldmysql 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8

mysql> create user root@'192.168.157.0/255.255.255.0' identified by 'qycx@12345678';

mysql> grant all on *.* to root@'192.168.157.0/255.255.255.0' with grant option;
Query OK, 0 rows affected (0.01 sec)
mysql> exit

2、部署第一台cloudstack management

yum localinstall cloudstack-common-4.18.0.0-1.ky10.aarch64.rpm -y
yum localinstall cloudstack-management-4.18.0.0-1.ky10.aarch64.rpm -y
#连接mysql，并通过root账号进行数据库配置，包括创建cloud账号、创建数据库表等
cloudstack-setup-databases cloud:qycx12345678@192.168.157.20 --deploy-as=root:qycx@12345678
#启动
cloudstack-setup-management

3、部署第二台cloudstack management

yum localinstall cloudstack-common-4.18.0.0-1.ky10.aarch64.rpm -y
yum localinstall cloudstack-management-4.18.0.0-1.ky10.aarch64.rpm -y
#连接mysql
cloudstack-setup-databases cloud:qycx12345678@192.168.157.20
#启动
cloudstack-setup-management

4、配置负载均衡

配置负载均衡，需要配置以下三个端口：

源端口	目的端口	协议
80/443	8080	HTTP
8250	8250	TCP
8096	8096	HTTP

yum install nginx
vim /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;events {worker_connections 1024;
}http {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;upstream backend_web {ip_hash;server 10.55.134.17:8080;server 10.55.134.15:8080;}upstream backend_8096 {ip_hash;server 10.55.134.17:8096;server 10.55.134.15:8096;}sendfile            on;tcp_nopush          on;tcp_nodelay         on;keepalive_timeout   65;types_hash_max_size 4096;include             /etc/nginx/mime.types;default_type        application/octet-stream;include /etc/nginx/conf.d/*.conf;server {listen       80;listen       [::]:80;server_name  _;location / {proxy_pass http://backend_web/;}}server {listen       8096;listen       [::]:8096;server_name  _;location / {proxy_pass http://backend_8096/;}}}
#TCP流
stream {upstream backend_8250 {hash $remote_addr consistent;server 10.55.134.17:8250;server 10.55.134.15:8250;}server {listen 8250;proxy_pass backend_8250;}
}
