linux---nginx服务nfs服务nginx反向代理三台web

一：nginx服务

1、二进制安装nginx包

[root@bogon ~]# systemctl disable firewalld        #关闭Firewalls自启动

　　Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

　　Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

[root@bogon ~]# systemctl stop firewalld            #关闭firework

[root@bogon ~]# yum install nginx -y                 #安装nginx服务

2、作为web服务修改配置文件

[root@bogon ~]# egrep -v "^$|^#|#" /etc/nginx/nginx.conf

user nginx;

worker_processes auto;

error_log /var/log/nginx/error.log;

pid /run/nginx.pid;

include /usr/share/nginx/modules/*.conf;

events {

worker_connections 1024;

}

http {

log_format main '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;

tcp_nopush on;

tcp_nodelay on;

keepalive_timeout 65;

types_hash_max_size 2048;

include /etc/nginx/mime.types;

default_type application/octet-stream;

include /etc/nginx/conf.d/*.conf;

server {

listen 80 default_server;

listen [::]:80 default_server;

server_name _;

root /usr/share/nginx/html;

include /etc/nginx/default.d/*.conf;

location / {

root /data/www/html;

index index.html;

}

error_page 404 /404.html;

location = /40x.html {

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

}

[root@bogon ~]# mkdir -p /data/www/html

[root@bogon ~]# echo "welcome oldgirl" > /data/www/html/index.html

3、让配置生效，验证配置

[root@bogon ~]# /usr/sbin/nginx -t #检查配置是否正确

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

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

[root@bogon ~]# systemctl start nginx #启动nginx服务

[root@bogon ~]# systemctl status nginx #查看nginx启动状态

二：nfs服务

1、二进制安装nfs

1	[root@bogon ~]# yum install rpcbind nfs-utils -y #NFS服务端和客户端都装。

2、作为共享存储挂载在三台web的网站根目录下

[root@nfs-server ~]# mkdir /share #创建挂载目录

[root@nfs-server ~]# cat /etc/exports #配置NFS SERVER

/share 192.168.152.0/24(rw,sync,fsid=0)

# 启动开机自启：

[root@nfs-server ~]# systemctl enable nfs-server.service

Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.

[root@nfs-server ~]# systemctl enable rpcbind.service

# 启动服务（必须先启动rpcbind服务）：

[root@nfs-server ~]# systemctl start rpcbind.service

[root@nfs-server ~]# systemctl start nfs-server.service

# 确定NFS服务器启动成功：

[root@nfs-server ~]# rpcinfo

[root@nfs-server ~]#

[root@nfs-server ~]# exportfs

/share 192.168.152.0/24

# 默认使用showmount -e 查看自己共享的服务，需要DNS能解析，不然容易报错。

# 此处添加HOSTS本地解析。

[root@nfs-server ~]# echo "192.168.152.134 nfs-server" >> /etc/hosts

[root@nfs-server ~]# showmount -e

Export list for nfs-server:

/share 192.168.152.0/24

# 客户端挂载：

[root@web01 ~]# mount -t nfs 192.168.152.134:/share /data/www/html/

[root@web02 ~]# mount -t nfs 192.168.152.134:/share /data/www/html/

[root@web03 ~]# mount -t nfs 192.168.152.134:/share /data/www/html/

[root@nfs-server ~]# showmount -a #显示已经与客户端连接上的目录信息

All mount points on nfs-server:

192.168.152.135:/share

192.168.152.136:/share

192.168.152.137:/share

3、实现在任意一台web上修改的结果，其余两台都可以看到

# others用户添加w权限

[root@nfs-server ~]# chmod -R o+w /share/

[root@nfs-server ~]# ll -d /share/

drwxr-xrwx 2 root root 23 Mar 20 16:38 /share/

# 测试结果

[root@web01 ~]# echo "welcome luchuangao" > /data/www/html/test.html

[root@web02 ~]# cat /data/www/html/test.html

welcome luchuangao

[root@web03 ~]# cat /data/www/html/test.html

welcome luchuangao

三：nginx反向代理三台web

（1）
Nginx反向代理：实现基于轮询的方式
http {
    upstream  pythonweb{
       server 192.168.2.3:80;
       server 192.168.2.4:80;
       server 192.168.2.5:80;
    }
  server{
   location / {
     proxy_pass http://pythonweb;
   }
  }
[root@bogon ~]# systemctl reload nginx.service
[root@bogon ~]# systemctl restart nginx.service
（2）
Nginx反向代理：实现基于权重的方式
http {
    upstream  pythonweb{
       server 192.168.2.3:80  weight=3;
       server 192.168.2.4:80;
       server 192.168.2.5:80;
    }
  server{
   location / {
     proxy_pass http://pythonweb;
   }
  }
[root@bogon ~]# systemctl reload nginx.service
[root@bogon ~]# systemctl restart nginx.service

（3）
Nginx反向代理：实现基于权重的方式
http {
    upstream  pythonweb{
       ip_hash;
       server 192.168.2.3:80;
       server 192.168.2.4:80;
       server 192.168.2.5:80;
    }
  server{
   location / {
     proxy_pass http://pythonweb;
   }
  }
[root@bogon ~]# systemctl reload nginx.service
[root@bogon ~]# systemctl restart nginx.service

四：nginx反向代理+三台web+nfs共享存储实现集群配置

# 在各个web服务器上挂载nfs

[root@web01 ~]# mount -t nfs 192.168.152.134:/share
/data/www/html/

[root@web02 ~]# mount -t nfs 192.168.152.134:/share
/data/www/html/

[root@web03 ~]# mount -t nfs 192.168.152.134:/share
/data/www/html/

[root@web01 ~]# echo "nfs ok" >
/data/www/html/index.html

# 浏览器访问进行验证

五：源码安装nginx，并按照作业一描述的那样去测试使用

#编译安装nginx

[root@nfs-server ~]# yum install gcc-* glibc-* openssl
openssl-devel pcre pcre-devel zlib zlib-devel -y

[root@nfs-server ~]# wget -q
http://nginx.org/download/nginx-1.10.3.tar.gz

[root@nfs-server ~]# ls nginx-1.10.3.tar.gz

nginx-1.10.3.tar.gz

[root@nfs-server ~]# tar -xf nginx-1.10.3.tar.gz

[root@nfs-server ~]# cd nginx-1.10.3/

[root@nfs-server nginx-1.10.3]# ./configure
--sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf
--pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module

[root@nfs-server nginx-1.10.3]# make && make
install

# 配置nginx.conf

[root@nfs-server ~]# cat
/usr/local/nginx/nginx.conf|egrep -v "^$|^#|#"

worker_processes 1;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

sendfile on;

keepalive_timeout 65;

server {

listen 80;

server_name localhost;

location / {

root /data/www/html;

index index.html index.htm;

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root html;

}

# 验证

[root@nfs-server ~]# /usr/local/nginx/nginx -t

nginx: the configuration file
/usr/local/nginx/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/nginx.conf
test is successful

[root@nfs-server ~]# /usr/local/nginx/nginx #启动nginx服务

[root@nfs-server ~]# echo 'goodbye oldboy' >
/data/www/html/index.html

#使用浏览器进行验证
