插件资源下载地址：https://github.com/ran-jit/tomcat-cluster-redis-session-manager/releases/tag/2.0.2
一、前置条件
JDK：jdk1.8.0_161， Nginx：nginx-1.13.9 ， tomcat：Apache Tomcat/8.5.16
Nginx：192.168.22.100
Redis：192.168.22.100
tomcat1：192.168.22.105：8081
tomcat2：192.168.22.106：8082
二、配置Nginx服务器的nginx.conf文件（/usr/local/nginx/conf）
user www;
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 65535;
use epoll;
}
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;
server_tokens off;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
#keepalive_timeout 0;
keepalive_timeout 10;
gzip on;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
#location /filestore/ {
# root /usr/local/nginx/html/filestore/;
# autoindex on;
#}
#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;
# }
#}
upstream tomcat {
server 192.168.22.105:8081 weight=1 fail_timeout=3s max_fails=2;
server 192.168.22.106:8082 weight=1 fail_timeout=3s max_fails=2;
}
##HTTPS server
server {
listen 443 ssl;
server_name localhost;
ssl on;
root html;
index index.html index.htm;
ssl_certificate /usr/local/nginx/cert/xxxxxxxxx.pem;
ssl_certificate_key /usr/local/nginx/cert/xxxxxxxx.key;
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto https;
proxy_redirect off;
proxy_connect_timeout 240;
proxy_send_timeout 240;
proxy_read_timeout 240;
# note, there is not SSL here! plain HTTP is used
proxy_pass http://tomcat;
}
}
}
三、下载tomcat-cluster-redis-session-manager插件
①下载完，解压然后将tomcat-cluster-redis-session-manager\tomcat-cluster-redis-session-manager\lib目录下的jar包复制到tomcat\lib下
②将tomcat-cluster-redis-session-manager\tomcat-cluster-redis-session-manager\conf\redis-data-cache.properties复制到tomcat\conf下。注意将redis.hosts改为redis对用的地址
#-- Redis data-cache configuration
#- redis hosts ex: 127.0.0.1:6379, 127.0.0.2:6379, 127.0.0.2:6380, ....
redis.hosts=192.168.22.100:6379
#- redis password (for stand-alone mode)
#redis.password=
#- set true to enable redis cluster mode
redis.cluster.enabled=false
#- redis database (default 0)
#redis.database=0
#- redis connection timeout (default 2000)
#redis.timeout=2000
四、修改tomcat目录下的contex.xml（/opt/weixins1/tomcat1/conf）
