安装之前优化一下内核参数以及系统内核版本

内核版本 4.17+ 
cat > /etc/modules-load.d/iptables.conf <<EOF
ip_tables
iptable_filter
EOF
然后重启服务器
mkdir -p /data/rancher_data

rancher安装主要是使用以下命令

docker run -d \
--name rancher-2.7.5 \
--restart=always \
--privileged \
-p 8081:80 \
-p 8082:443 \
-v /data/rancher_data:/var/lib/rancher \
-v /data/rancher_data/kubelet:/var/lib/kubelet \
rancher/rancher:v2.7.5

nginx的配置为

upstream rancher-rancher {#server 127.0.0.1:8081;server 127.0.0.1:8082;
}
server {listen       80;server_name  rancher.abc.com;rewrite ^/(.*)$ https://$host/$1;
}server {listen       443 ssl;server_name  rancher.abc.com;ssl_certificate  /server//abc.crt;ssl_certificate_key /server/abc.com.key;ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;ssl_ciphers         HIGH:!aNULL:!MD5;location / {proxy_pass   https://rancher-rancher;proxy_set_header Host $host;proxy_http_version 1.1;proxy_set_header Upgrade $http_upgrade;proxy_set_header Connection "upgrade";add_header 'Access-Control-Allow-Origin' '*';add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE';add_header 'Access-Control-Allow-Credentials' 'true';if ( $request_method = 'OPTIONS' ) {return 200;}}
}

会有报错

E0509 08:52:25.505821      33 upgradeaware.go:365] Proxy upgrade error: invalid upgrade response: status code 201

解决办法

upstream rancher-rancher {#server 127.0.0.1:8081;server 127.0.0.1:8082;
}
server {listen       80;server_name  rancher.abc.com;rewrite ^/(.*)$ https://$host/$1;
}server {listen       443 ssl;server_name  rancher.abc.com;ssl_certificate  /server/abc.com.crt;ssl_certificate_key /server/abc.com.key;ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;ssl_ciphers         HIGH:!aNULL:!MD5;location / {proxy_pass   https://rancher-rancher;proxy_set_header Host $host;if ( $request_method = 'OPTIONS' ) {return 200;}}
}
