寫這篇文章也是爲了記錄個人履試不爽的過程,怕之後好久不用就忘了,感謝園子及貢獻者。
一、三個CentOS7系統準備
在147機子基礎上完整複製了182及183,複製好後同樣要刷新一下網絡的MAC地址。
二、安裝Jexus《CentOS7 安裝 jexus-5.8.2-x64》本想只安裝182:8888,183:7777,index.html內容設置不一樣,但因設置好後始終把錯誤:"502 Bad Gateway"
因而將147:8080也安裝 上並設置
三、安裝Nginx
#yum update
更新一些庫和必要的支持,完了以後去下載一個nginx的最新版,現在我責編的版本是1.7.7:
#wget http://nginx.org/download/nginx-1.13.6.tar.gz
解壓縮
#tar -zvxf nginx-1.13.6.tar.gz
#cd nginx-1.13.6
nginx有不少不少編譯配置項,但因爲我這是第一篇筆記,因此我基本上都使用了默認的配置:
#./configure --with-http_ssl_module --with-http_gzip_static_module
我只加了兩個選項,--with-http_ssl_module表示使用ssl模塊,--with-http_gzip_static_module表示使用gzip模塊,其它更詳細的配置就要參考nginx的文檔了:http://nginx.org/en/docs/configure.html若是沒configure成功(會顯示XXX not found),那是由於有些依賴沒有被正確安裝.那麼先安裝一下這些依賴條件,一般是pcre,zlib這些,這麼一下就基本上能夠了:
#yum install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel#make
#make install可執行文件就會被安裝在: /usr/sbin/nginx (默認配置)
nginx基本使用
程序位置:/usr/local/nginx/sbin/nginx
配置文件位置:/usr/local/nginx/conf/nginx.conf
啓動nginx:
#cd /usr/local/nginx/sbin/
#./nginx若是運行的時候不帶-c參數,那就採用默認的配置文件,即/etc/nginx/nginx.conf
查看運行進程狀態:
# ps aux | grep nginx打開瀏覽器,訪問http://localhost/看看nginx的默認頁面:
中止nginx:
#./nginx -s stop重啓nginx(配置文件變更後須要重啓才能生效):
#./nginx -s reload檢查配置文件是否正確:
#./nginx -t查看nginx的pid:
cat /usr/local/nginx/logs/nginx.pid查看nginx版本
$ ./nginx -v回頭看編譯配置
# ./nginx -V
四、Nginx配置
#vi /etc/nginx/nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}http {
include /etc/nginx/mime.types;
default_type application/octet-stream;sendfile on;
keepalive_timeout 65;
server {
listen 80;server_name localhost;
location / {
proxy_pass http://192.168.5.147:8080;
}}
}
按上面這樣配置按理應該能夠訪問http://192.168.5.147 顯示的應該是147:8080的網頁內容,但 就是報錯了
因而,這才查看日誌
#vi /var/log/nginx/error.log
2017/11/03 05:23:53 [crit] 1331#1331: *12 connect() to 192.168.5.147:8080 failed
(13: Permission denied) while connecting to upstream, client: 192.168.5.65, server: localhost,
request: "GET / HTTP/1.1", upstream: "http://192.168.5.147:8080/", host: "192.168.5.147"
園子中搜「(13: Permission denied) while connecting to upstream, client:」就找到緣由,
type=AVC msg=audit(1509701033.988:119): avc: denied { name_connect } for pid=1331
comm="nginx" dest=8080 scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:object_r:http_cache_port_t:s0 tclass=tcp_socket
處理:
#setsebool -P httpd_can_network_connect 1
到這裏應該就正常了,反向代理的後面設置
下面是設置兩個服務器
user nginx;
worker_processes 1;error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}http {
include /etc/nginx/mime.types;
default_type application/octet-stream;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;keepalive_timeout 65;
#gzip on;
upstream test {
server 192.168.5.182:8888;
server 192.168.5.183:7777;
}
server {
listen 80;
server_name localhost;location / {
proxy_pass http://test;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Cookie $http_cookie;
}
}
}
