linux---nginx服務nfs服務nginx反向代理三台web

一：nginx服務

1、二進制安裝nginx包

[root@bogon ~]# systemctl disable firewalld        #關閉Firewalls自啟動
　　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            #關閉firework

[root@bogon ~]# yum install nginx -y                 #安裝nginx服務

2、作為web服務修改配置檔案

[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、讓配置生效，驗證配置

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

　　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 #啟動nginx服務

[root@bogon ~]# systemctl status nginx #檢視nginx啟動狀态

二：nfs服務

1、二進制安裝nfs

1	[root@bogon ~]# yum install rpcbind nfs-utils -y #NFS服務端和用戶端都裝。

2、作為共享存儲挂載在三台web的網站根目錄下

[root@nfs-server ~]# mkdir /share #建立挂載目錄

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

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

# 啟動開機自啟：

[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

# 啟動服務（必須先啟動rpcbind服務）：

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

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

# 确定NFS伺服器啟動成功：

[root@nfs-server ~]# rpcinfo

[root@nfs-server ~]#

[root@nfs-server ~]# exportfs

/share 192.168.152.0/24

# 預設使用showmount -e 檢視自己共享的服務，需要DNS能解析，不然容易報錯。

# 此處添加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

# 用戶端挂載：

[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 #顯示已經與用戶端連接配接上的目錄資訊

All mount points on nfs-server:

192.168.152.135:/share

192.168.152.136:/share

192.168.152.137:/share

3、實作在任意一台web上修改的結果，其餘兩台都可以看到

# others使用者添加w權限

[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/

# 測試結果

[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

三：nginx反向代理三台web

（1）

Nginx反向代理：實作基于輪詢的方式

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：實作基于權重的方式

server 192.168.2.3:80 weight=3;

（3）

ip_hash;

四：nginx反向代理+三台web+nfs共享存儲實作叢集配置

# 在各個web伺服器上挂載nfs

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

/data/www/html/

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

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

[root@web01 ~]# echo "nfs ok" >

/data/www/html/index.html

# 浏覽器通路進行驗證

五：源碼安裝nginx，并按照作業一描述的那樣去測試使用

#編譯安裝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;

worker_connections 1024;

include mime.types;

default_type application/octet-stream;

sendfile on;

keepalive_timeout 65;

listen 80;

server_name localhost;

root /data/www/html;

index index.html index.htm;

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root html;

# 驗證

[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 #啟動nginx服務

[root@nfs-server ~]# echo 'goodbye oldboy' >

/data/www/html/index.html

#使用浏覽器進行驗證
