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

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
|
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
