Linux基础服务
作业一：nginx服务
1、二进制安装nginx包
[root@bogon ~]# systemctl disable firewalld #关闭Firewalld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firewalld [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

#使用浏览器验证是否可以正常访问web
作业二：nfs服务
拓扑图：
1、二进制安装nfs
[root@nfs-server ~]# 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
作业三：nginx反向代理三台web
参考链接：http://nginx.org/en/docs/http/load_balancing.html
1、实现基于轮询的方式调度三台web，并验证结果
[root@nfs-server ~]# !egrep
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 {

http {
upstream luchuangao {

}
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 / {
proxy_pass http://luchuangao;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
[root@nfs-server ~]# /usr/sbin/nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@nfs-server ~]# systemctl reload nginx
[root@web01 ~]# echo "web01" > /data/www/html/index.html [root@web02 ~]# echo "web02" > /data/www/html/index.html [root@web03 ~]# echo "web03" > /data/www/html/index.html
# 浏览器进行验证
2、实现基于权重的方式调度三台web，并验证结果
[root@nfs-server ~]# /usr/sbin/nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@nfs-server ~]# /usr/sbin/nginx -s reload
[root@nfs-server ~]# egrep -v "#|^$|^#" /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
upstream luchuangao {
server 192.168.152.135:80 weight=3;
server 192.168.152.136:80;
server 192.168.152.137:80;
}
log_format main '$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;

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 / {
proxy_pass http://luchuangao;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
3、实现基于hash的方式调用三台web，并验证结果
[root@nfs-server ~]# /usr/sbin/nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@nfs-server ~]# /usr/sbin/nginx -s reload
[root@nfs-server ~]# 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;

worker_connections 1024;
}
http {
upstream luchuangao {
ip_hash;
server 192.168.152.135:80;
server 192.168.152.136:80;
server 192.168.152.137:80;
}
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 / {
proxy_pass http://luchuangao;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
作业四：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
作业五：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 / {

}
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
