实现双主配置
第一个历程: 编写keepalived服务配置文件
lb01
vrrp_instance oldboy {
state MASTER
interface eth0
virtual_router_id 63
priority 110
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.0.0.3
}
}
vrrp_instance oldgirl {
state BACKUP
interface eth0
virtual_router_id 64
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.0.0.4
}
}
lb02
vrrp_instance oldboy {
state BACKUP
interface eth0
virtual_router_id 63
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.0.0.3
}
}
vrrp_instance oldgirl {
state MASTER
interface eth0
virtual_router_id 64
priority 110
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.0.0.4
}
}
第二个历程: 修改负载均衡服务配置文件
方式一:
server {
listen 10.0.0.3:80;
server_name www.oldboy.com;
location / {
proxy_pass http://oldboy;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
server {
listen 10.0.0.4:80;
server_name bbs.oldboy.com;
location / {
proxy_pass http://oldboy;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
方式二:
server {
listen 10.0.0.3:80;
listen 10.0.0.4:80;
server_name localhost;
location / {
proxy_pass http://oldboy;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
网站安全访问概念介绍 HTTPs(secure)
1. 数据的机密性 对称加密算法 私钥和公钥 保护好算法信息 发送方(私钥/公钥) --- 接收方(私钥/公钥)
2. 数据的完整性 对称加密算法 私钥和公钥 保护好特征码
3. 身份认证问题 非对称加密算法 私钥在服务器上保留好 公钥进行分发
公钥 === 证书(身份证)
CA证书颁发机构(你妈)
如何实现HTTPs安全访问网站
第一个历程: 创建私钥和公钥(证书)
cd /etc/nginx/
openssl genrsa -idea -out server.key 2048
genrsa --- 创建什么类型私钥
idea --- 需要给私钥文件设置密码
out --- 创建生成一个私钥文件
openssl req -days 36500 -x509 -sha256 -nodes -newkey rsa:2048 -keyout server.key -out server.crt
req --- 创建一个证书文件
days --- 证书文件有效期(默认 天)
x509 --- 证书文件格式
sha256 --- 指定生成证书算法
nodes --- 去除私钥的密码生成证书
keyout --- 指定加载私钥文件
out --- 生成的证书信息
第二个历程: 在nginx程序中,编写配置文件开启HTTPS功能,加载私钥和公钥信息
ssl_certificate ssl_key/server.crt;
ssl_certificate_key ssl_key/server.key;
[root@web02 nginx]# cat /etc/nginx/conf.d/www.conf
server {
listen 443 ssl;
server_name www.oldboy.com www.jd.com;
root /html/www;
index index.html;
ssl_certificate server.crt;
ssl_certificate_key server.key;
}
第三个历程: 进行HTTP访问跳转HTTPS功能配置
server {
listen 80;
server_name www.oldboy.com;
rewrite ^/(.*)$ https://$host/$1 redirect;
}
server {
listen 443 ssl;
server_name www.oldboy.com www.jd.com;
root /html/www;
index index.html;
ssl_certificate server.crt;
ssl_certificate_key server.key;
}
利用负载均衡实现HTTPs访问过程
方式一: 全网服务器都配置证书和私钥信息
用户客户端访问 --- lb01 --- web节点
www.oldboy.com http://www.oldboy.com
https://www.oldboy.com ---> listen 443 ssl
第一个历程: 编写lb负载均衡配置文件
upstream oldboy {
#server 10.0.0.7:443;
server 10.0.0.8:443;
#server 10.0.0.9:80;
}
server {
listen 80;
server_name localhost;
rewrite ^/(.*)$ https://$host/$1 redirect;
}
server {
listen 443 ssl;
server_name localhost;
ssl_certificate server.crt;
ssl_certificate_key server.key;
location / {
proxy_pass https://oldboy;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
第二个历程: web节点配置
server {
listen 443 ssl;
server_name www.oldboy.com www.jd.com;
root /html/www;
index index.html;
ssl_certificate server.crt;
ssl_certificate_key server.key;
}
方式二: 负载均衡服务器配置证书和私钥信息
用户客户端访问 --- lb01 ---> web节点
www.oldboy.com http://www.oldboy.com
https://www.oldboy.com ---> listen 80
第一个历程: 负载均衡配置信息
upstream oldboy {
#server 10.0.0.7:443;
server 10.0.0.8:80;
#server 10.0.0.9:80;
}
server {
listen 80;
server_name localhost;
rewrite ^/(.*)$ https://$host/$1 redirect;
}
server {
listen 443 ssl;
server_name localhost;
ssl_certificate server.crt;
ssl_certificate_key server.key;
location / {
proxy_pass http://oldboy;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
第二个历程: web节点配置信息
server {
listen 80;
server_name www.oldboy.com www.jd.com;
root /html/www;
index index.html;
}
利用HTTPs访问动态页面 WordPress
第一个历程: 修改配置文件信息
修改负载均衡配置文件:
upstream oldboy {
#server 10.0.0.7:443;
server 10.0.0.8:443;
#server 10.0.0.9:80;
}
server {
listen 80;
server_name localhost;
rewrite ^/(.*)$ https://$host/$1 redirect;
}
server {
listen 443 ssl;
server_name localhost;
ssl_certificate server.crt;
ssl_certificate_key server.key;
location / {
proxy_pass https://oldboy;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
web服务器配置过程
server {
listen 443 ssl;
server_name blog.oldboy.com blog.oldgirl.com;
ssl_certificate server.crt;
ssl_certificate_key server.key;
location / {
root /html/blog;
index index.php index.html;
}
location ~ \.php$ {
root /html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS on;
include fastcgi_params;
}
}
第二个历程: 修改wordpress后台信息
修改地址为 https://blog.oldboy.com
第三个历程: 重启nginx程序
