Linux：web服务基于IP和域名部署

配置基于IP的虚拟主机

# 添加两个IP
[root@server100 ~]# ip addr add 172.25.254.10/24 dev eth0
[root@server100 ~]# ip addr add 172.25.254.20/24 dev eth0# 这个命令是专门用来查看IP信息的
[root@server100 ~]# ip addr

include /usr/share/nginx/modules/*.conf;# 创建扩展配置文件配置虚拟主机
[root@server100 conf.d]# vim /etc/nginx/conf.d/vhosts.conf# 配置内容如下
server {listen 172.25.254.10:80;root /usr/share/nginx/virtual/10;index index.html;
}server {listen 172.25.254.20:80;root /usr/share/nginx/virtual/20;index index.html;
}# 创建对应目录以及创建网页文件
[root@server100 conf.d]# mkdir -p /usr/share/nginx/virtual/{10,20}
[root@server100 conf.d]# echo "10" > /usr/share/nginx/virtual/10/index.html
[root@server100 conf.d]# echo "20" > /usr/share/nginx/virtual/20/index.html# 访问测试
[root@server100 conf.d]# curl 172.25.254.10
10
[root@server100 conf.d]# curl 172.25.254.20
20

配置基于域名的虚拟主机（最常用）

# 配置扩展配置文件
[root@server100 conf.d]# vim /etc/nginx/conf.d/vhosts.conf
server {listen 172.25.254.10:80;root /usr/share/nginx/virtual/10;index index.html;
}server {listen 172.25.254.20:80;root /usr/share/nginx/virtual/20;index index.html;
}# 主要是下面这两段
server{listen 80;server_name news.shanxin.org;root /usr/share/nginx/virtual/shanxin/news;index   index.html;
}server{listen 80;server_name bbs.shanxin.org;root /usr/share/nginx/virtual/shanxin/bbs;index   index.html;
}# 创建对应目录以及创建网页文件
[root@server100 conf.d]# mkdir -p /usr/share/nginx/virtual/shanxin/{news,bbs}
[root@server100 conf.d]# echo "news" > /usr/share/nginx/virtual/shanxin/news/index.html
[root@server100 conf.d]# echo "bbs" > /usr/share/nginx/virtual/shanxin/bbs/index.html# 添加Linux系统的本机域名映射文件
[root@server100 conf.d]# vim /etc/hosts172.25.254.100 server100.timeinglee.org www.shanxin.org news.shanxin.org bbs.shanxin.org# 访问测试
# 访问测试
[root@server100 conf.d]# curl news.shanxin.org
news
[root@server100 conf.d]# curl bbs.shanxin.org
bbs

查看nginx错误日志信息，排查错误还有通过日志

[root@server100 conf.d]# cat /var/log/nginx/error.log[root@server100 ~]# tree /var/log/nginx/
/var/log/nginx/
├── access.log # 通过日志
└── error.log0 directories, 2 files
