windows下tomcat集群配置
本次测试的环境为windows 10
使用到的工具
nginx-1.17.2
apache-tomcat-8.5.43
apache-tomcat-9.0.20
JDK1.8
局域网中的两台电脑
192.168.1.199
192.168.1.198
其中192.168.1.199上边运行的 apache-tomcat-9.0.20
192.168.1.198上边运行的 nginx-1.17.2 apache-tomcat-8.5.43
1)192.168.1.199上的tomcat的配置
192.168.1.199上的Tomcat的端口修改为8081------->端口修改,在conf下的server.xml中
<Connector port="8081" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
启动tomcat---->和conf同级的bin目录里,我习惯通过cmd cd进入,执行startup.bat
成功启动了,端口是8081
2)192.168.1.198上的Tomcat配置和nginx的配置
tomcat的配置方式同上,只不过端口修改为8080
nginx的配置如下
#user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include 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 logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; upstream myserver { server 192.168.1.198:8080;//第一台tomcat server 192.168.1.199:8081;//第二台tomcat #可以加上权重weight=1-10,ip_hash,max_fails=2 fail_timeout=30s,重试次数,超时等配置 } server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { proxy_pass http://myserver; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
这是nginx.conf配置文件的全部内容
其中的核心就是http 和 server
server就相当于一台虚拟机
这样配置好,然后启动nginx
3)测试
在192.168.1.199上访问192.168.1.198
第一次访问
第二次访问
可以看到,
Apache Tomcat/8.5.43 切换成
Apache Tomcat/9.0.20
可能需要多刷新几次才有看到效果,
同样的道理,理论上可以配置无数台tomcat,参与集群。
我们都只是茫茫星辰中的一粒沙。
