linux-nginx服务nfs服务nginx反向代理三台web

Posted 2020-09-05 xuaijun

 

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 ● nginx.service - The nginx HTTP and reverse proxy server    Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)    Active: active (running) since Mon 2017-03-20 15:23:29 CST; 44s ago   Process: 3072 ExecStart=/usr/sbin/nginx (code=exited, status=0/SUCCESS)   Process: 3069 ExecStartPre=/usr/sbin/nginx -t (code=exited, status=0/SUCCESS)   Process: 3068 ExecStartPre=/usr/bin/rm -f /run/nginx.pid (code=exited, status=0/SUCCESS)  Main PID: 3075 (nginx)    CGroup: /system.slice/nginx.service            ├─3075 nginx: master process /usr/sbin/nginx            └─3076 nginx: worker process   Mar 20 15:23:29 bogon systemd[1]: Starting The nginx HTTP and reverse proxy server... Mar 20 15:23:29 bogon nginx[3069]: nginx: the configuration file /etc/nginx/nginx.conf syntax is ok Mar 20 15:23:29 bogon nginx[3069]: nginx: configuration file /etc/nginx/nginx.conf test is successful Mar 20 15:23:29 bogon systemd[1]: Failed to read PID from file /run/nginx.pid: Invalid argument Mar 20 15:23:29 bogon systemd[1]: Started The nginx HTTP and reverse proxy server.

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    program version netid     address                service    owner     100000    4    tcp6      ::.0.111               portmapper superuser     100000    3    tcp6      ::.0.111               portmapper superuser     100000    4    udp6      ::.0.111               portmapper superuser     100000    3    udp6      ::.0.111               portmapper superuser     100000    4    tcp       0.0.0.0.0.111          portmapper superuser     100000    3    tcp       0.0.0.0.0.111          portmapper superuser     100000    2    tcp       0.0.0.0.0.111          portmapper superuser     100000    4    udp       0.0.0.0.0.111          portmapper superuser     100000    3    udp       0.0.0.0.0.111          portmapper superuser     100000    2    udp       0.0.0.0.0.111          portmapper superuser     100000    4    local     /var/run/rpcbind.sock  portmapper superuser     100000    3    local     /var/run/rpcbind.sock  portmapper superuser     100005    1    udp       0.0.0.0.78.80          mountd     superuser     100005    1    tcp       0.0.0.0.78.80          mountd     superuser     100005    1    udp6      ::.78.80               mountd     superuser     100005    1    tcp6      ::.78.80               mountd     superuser     100005    2    udp       0.0.0.0.78.80          mountd     superuser     100005    2    tcp       0.0.0.0.78.80          mountd     superuser     100024    1    udp       0.0.0.0.129.33         status     29     100005    2    udp6      ::.78.80               mountd     superuser     100024    1    tcp       0.0.0.0.171.119        status     29     100024    1    udp6      ::.206.85              status     29     100005    2    tcp6      ::.78.80               mountd     superuser     100005    3    udp       0.0.0.0.78.80          mountd     superuser     100024    1    tcp6      ::.207.20              status     29     100005    3    tcp       0.0.0.0.78.80          mountd     superuser     100005    3    udp6      ::.78.80               mountd     superuser     100005    3    tcp6      ::.78.80               mountd     superuser     100003    3    tcp       0.0.0.0.8.1            nfs        superuser     100003    4    tcp       0.0.0.0.8.1            nfs        superuser     100227    3    tcp       0.0.0.0.8.1            nfs_acl    superuser     100003    3    udp       0.0.0.0.8.1            nfs        superuser     100003    4    udp       0.0.0.0.8.1            nfs        superuser     100227    3    udp       0.0.0.0.8.1            nfs_acl    superuser     100003    3    tcp6      ::.8.1                 nfs        superuser     100003    4    tcp6      ::.8.1                 nfs        superuser     100227    3    tcp6      ::.8.1                 nfs_acl    superuser     100003    3    udp6      ::.8.1                 nfs        superuser     100003    4    udp6      ::.8.1                 nfs        superuser     100227    3    udp6      ::.8.1                 nfs_acl    superuser     100021    1    udp       0.0.0.0.220.240        nlockmgr   superuser     100021    3    udp       0.0.0.0.220.240        nlockmgr   superuser     100021    4    udp       0.0.0.0.220.240        nlockmgr   superuser     100021    1    tcp       0.0.0.0.156.92         nlockmgr   superuser     100021    3    tcp       0.0.0.0.156.92         nlockmgr   superuser     100021    4    tcp       0.0.0.0.156.92         nlockmgr   superuser     100021    1    udp6      ::.211.174             nlockmgr   superuser     100021    3    udp6      ::.211.174             nlockmgr   superuser     100021    4    udp6      ::.211.174             nlockmgr   superuser     100021    1    tcp6      ::.171.11              nlockmgr   superuser     100021    3    tcp6      ::.171.11              nlockmgr   superuser     100021    4    tcp6      ::.171.11              nlockmgr   superuser [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
