在CentOS 7上安装Haproxy环境,可以按照以下步骤进行:
- 安装EPEL仓库:因为Haproxy的软件包通常在这个仓库中。执行以下命令:
sudo yum install epel-release
- 安装Haproxy:执行以下命令:
sudo yum install haproxy
- 启动并设置开机自启动Haproxy服务。执行以下命令:
sudo systemctl start haproxy
sudo systemctl enable haproxy
- 配置Haproxy。编辑Haproxy配置文件(通常位于
/etc/haproxy/haproxy.cfg
),根据实际需求添加负载均衡规则。例如:
global
log /dev/log local0
maxconn 4096
chroot /var/lib/haproxy
user haproxy
group haproxy
daemon
defaults
log global
mode http
option httplog
option dontlognull
timeout connect 5000
timeout client 50000
timeout server 50000
frontend http_frontend
bind *:80
default_backend http_backends
backend http_backends
balance roundrobin
server web1 backend1.example.com:80 check cookie mycookie=123456 path=/check cookie_domain=.example.com cookie_path=/ check_http_x_forwarded_for on;server web2 backend2.example.com:80 check cookie mycookie=123456 path=/check cookie_domain=.example.com cookie_path=/ check_http_x_forwarded_for on;
