centos6.8下配置https服务器

1.1 环境

l 系统环境：内核环境为2.6.32版本 64位的CentOS release 6.8 (Final)

[root@localhost ~]# uname -a

Linux localhost 2.6.32-696.3.1.el6.x86_64 #1 SMP Tue May 30 19:52:55 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

[root@localhost ~]# cat /etc/redhat-release

CentOS release 6.8 (Final)

l 网络环境：确保能够访问网络

[root@localhost ~]# ping -c 2 www.baidu.com

PING www.a.shifen.com (220.181.112.244) 56(84) bytes of data.

64 bytes from 220.181.112.244: icmp_seq=1 ttl=53 time=4.82 ms

64 bytes from 220.181.112.244: icmp_seq=2 ttl=53 time=4.89 ms

--- www.a.shifen.com ping statistics ---

2 packets transmitted, 2 received, 0% packet loss, time 1006ms

rtt min/avg/max/mdev = 4.820/4.856/4.892/0.036 ms

1.2 安装nginx：这里直接使用yum安装

[root@localhost ~]# yum install -y nginx

Loaded plugins: fastestmirror

Setting up Install Process

Repository epel is listed more than once in the configuration

Determining fastest mirrors

……

………省略

Complete!

[root@localhost ~]# rpm -q nginx

nginx-1.10.2-1.el6.x86_64

可以看到yum 安装的nginx的版本为nginx-1.10.2

1.3 上传已经相关证书

[root@localhost ~]# mkdir -p /etc/nginx/ssl

[root@localhost ~]# cd /etc/nginx/ssl

上传文件（此处可根据具体情况上传文件）

[root@localhost ssl]# yum install -y lrzsz

[root@localhost ssl]# rz -y

弹出对话框，双击选中相关证书文件点击ok上传到服务器/etc/nginx/ssl目录下

1.4 配置nginx文件

清空原有的ssl.conf文件

[root@localhost ssl]# >/etc/nginx/conf.d/ssl.conf

加入以下内容，并根据自己的需求更改IP，域名和证书文件

[root@localhost ssl]# cat /etc/nginx/conf.d/ssl.conf

}

备注：红色地方为需要自己更改的地方

备注：xxx.xxx.xxx.xxx 为您需要增加的后端的IP

1.5 检查配置并启动nginx

检查配置：是否正确（看到ok和successful表示配置正确）

[root@localhost ~]# /etc/init.d/nginx configtest

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

启动服务

[root@localhost ~]# /etc/init.d/nginx start

Starting nginx: [ OK ]

[root@localhost ~]# netstat -lnptu|grep "nginx"

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 15260/nginx

tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 15260/nginx

可以看到已经开启了80和443端口，表示nginx已经启动成功

1.6 防火墙设置

防火墙应根据服务器具体情况配置：

这边防火墙配置如下：

[root@localhost ~]# cat /etc/sysconfig/iptables

*filter

:INPUT ACCEPT [0:0]

:FORWARD ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]

-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

-A INPUT -p icmp -j DROP

-A INPUT -i lo -j ACCEPT

-A INPUT -p tcp -m state --state NEW -m multiport --dports 22 -j ACCEPT

-A INPUT -p tcp -m state --state NEW -m multiport --dports 80,443 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited

-A FORWARD -j REJECT --reject-with icmp-host-prohibited

COMMIT

重启防火墙

[root@localhost ~]# /etc/init.d/iptables restart

关闭selinux

[root@localhost ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

[root@localhost ~]# setenforce 0

到此https配置基本完成。
