CA证书服务
安装
[root@server ~]# yum -y install openssl
创建根证书所需的目录及文件
[root@server ~]# cd /etc/pki/
[root@server pki]# ls
ca-trust consumer entitlement java product product-default rpm-gpg rsyslog tls
[root@server pki]# mkdir CA
[root@server pki]# touch CA/serial
[root@server pki]# touch CA/index.txt
[root@server pki]# mkdir CA/private
指明证书的开始编号
[root@server pki]# cd CA/
[root@server CA]# echo 01 > serial
生成根证书的私钥（注意：私钥的文件名与存放位置要与配置文件中的设置相匹配）
[root@server CA]# openssl genrsa -out /etc/pki/CA/private/cakey.pem 2048
Generating RSA private key, 2048 bit long modulus (2 primes)
...+++++
..........................................................+++++
e is 65537 (0x010001)
[root@server CA]#
生成自签证书，即根证书，自签证书的存放位置也要与配置文件中的设置匹配，生成证书时需 要填写相应的信息
[root@server CA]# openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -out cacert.pem
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:cn
State or Province Name (full name) []:hb
Locality Name (eg, city) [Default City]:wh
Organization Name (eg, company) [Default Company Ltd]:jxrt
Organizational Unit Name (eg, section) []:zxxq
Common Name (eg, your name or your server's hostname) []:server
Email Address []:
[root@server CA]#
服务端（RS1与RS2）
创建证书存放路径并生成私钥
[root@RS1 ~]# cd /etc/httpd/
[root@RS1 httpd]# ls
conf conf.d conf.modules.d logs modules run state
[root@RS1 httpd]# mkdir ssl
[root@RS1 httpd]# cd ssl/
[root@RS1 ssl]# openssl genrsa -out test.key 2048
Generating RSA private key, 2048 bit long modulus (2 primes)
.................+++++

e is 65537 (0x010001)
[root@RS1 ssl]#
生成证书文件
[root@RS1 ssl]# openssl req -new -key test.key -out test.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.

Locality Name (eg, city) [Default City]:wh
Organization Name (eg, company) [Default Company Ltd]:jxrt
Organizational Unit Name (eg, section) []:zxxq
Common Name (eg, your name or your server's hostname) []:RS1
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
[root@RS1 ssl]# ls
test.csr test.key
把这个证书传到CA服务器根下面 ，去CA服务器上面创建一个req文件夹
[root@server CA]# mkdir req
[root@RS1 ssl]# scp test.csr 192.168.10.201:/etc/pki/CA/req
apache服务端传过来的csr请求文件给CA服务器来颁 发
[root@server CA]# mkdir newcerts
[root@server CA]# cd req/
[root@server req]# openssl ca -in /etc/pki/CA/req/test.csr -out /etc/pki/CA/req/test.crt
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature
Signature ok

Data Base Updated
[root@server req]# ls
test.crt test.csr
把CA服务器上面的crt证书文件传送给apache服务器下面的/etc/httpd/ssl文件
[root@server req]# scp test.crt 192.168.10.202:/etc/httpd/ssl
证书配置
给httpd安装ssl模块
[root@RS1 ssl]# yum -y install mod_ssl
查看密钥与证书文件
[root@RS1 ~]# ls /etc/httpd/ssl/
test.crt test.csr test.key
[root@RS1 ~]#
配置ssl
[root@RS1 ~]# vim /etc/httpd/conf.d/ssl.conf
·····
# General setup for the virtual host, inherited from global configuration
DocumentRoot "/var/www/html" ##取消注释
ServerName www.example.com:443 ##取消注释
·····
·····
SSLCertificateFile /etc/httpd/ssl/http.crt ##修改证书存放位置
# Server Private Key:
# If the key is not combined with the certificate, use this
# directive to point at the key file. Keep in mind that if
# you've both a RSA and a DSA private key you can configure
# both in parallel (to also allow the use of DSA ciphers, etc.)
# ECC keys, when in use, can also be configured in parallel
SSLCertificateKeyFile /etc/httpd/ssl/http.key ##修改密钥存放位置

重启httpd
[root@RS1 ~]# systemctl restart httpd
[root@RS1 ~]# ss -antl

RS2重复安装以上步骤
追加文件测试
[root@RS1 html]# echo me 192.168.240.60 > index.html
[root@RS1 html]# systemctl restart httpd
[root@RS2 html]# echo me 192.168.240.40 > index.html
[root@RS2 html]# systemctl restart httpd
安装haproxy
安装需要的工具
[root@server ~]# yum -y install make gcc pcre-devel bzip2-devel openssl-devel systemd-devel
提前准备安装压缩包并解压
[root@server ~]# ls
anaconda-ks.cfg haproxy-2.4.7.tar.gz
[root@server ~]# tar xf haproxy-2.4.7.tar.gz -C /usr/local/
创建haproxy用户
[root@server ~]# useradd -r -M -s /sbin/nolong haproxy
进入解压目录进行编译安装
[root@server ~]# cd /usr/local/haproxy-2.4.7/
[root@server haproxy-2.4.7]# make -j $(nproc) TARGET=linux-glibc \
> USE_OPENSSL=1 USE_PCRE=1 USE_SYSTEMD=1
[root@server haproxy-2.4.7]# make install PREFIX=/usr/local/haproxy
##安装完成
[root@server local]# ls haproxy
doc sbin share
给RS1、RS2设置内核参数
[root@RS1 ~]# echo net.ipv4.ip_nonlocal_bind =1 >> /etc/sysctl.conf
[root@RS1 ~]# echo net.ipv4.ip_forward = 1 >> /etc/sysctl.conf
[root@RS1 ~]# sysctl -p
net.ipv4.ip_nonlocal_bind = 1
net.ipv4.ip_forward = 1
[root@RS1 ~]#
RS2操作同上
提供配置文件
[root@server ~]# mkdir /etc/haproxy
[root@server ~]# vim /etc/haproxy/haproxy.cfg
