nginx代理服务器,仅实现了http，https看文档第25章4.5.4.3
[root@zhao ~]# egrep -v "#|^ $" /apps/nginx/conf/nginx.conf worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; upstream tomcat { # ip_hash; #hash$ cookie_jsession 写的不好基于cooke的反正
server 10.0.0.8:8080;
server 10.0.0.28:8080;
}
server {
listen 80;
server_name www.magedu.org;
location / {
root html;
index index.html index.htm;
proxy_pass http://tomcat;
proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For$ proxy_add_x_forwarded_for;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

会话session粘性
1.tomcat自带的session复制
2.memcached
3.redis

安装memcached
yum install -y memcached
[root@myre ~]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"

OPTIONS="-l 127.0.0.1,::1"

[root@myre ~]# systemctl restart memcached.service

新的机器10.0.0.18
使用redis保持会话session
yum install redis -y
[root@myre ~]# vim /etc/redis.conf
bind 0.0.0.0
[root@myre ~]# systemctl enable --now redis

把包放在tomcat机器下的目录里，2台都做，不知道哪几个包全拷了11个
[root@zhao lib]# ls /usr/local/tomcat/lib/ |grep jedis.jar
jedis-3.0.0.jar
然后修改tomcat的配置文件，倒数第二行开始加
[root@redis1 lib]# vim /usr/local/tomcat/conf/context.xml
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="redis://10.0.0.18"
sticky="false"
sessionBackupAsync="false"
lockingMode="uriPattern:/path1|/path2"
requestUriIgnorePattern="..(ico|png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
/>
</Context>

[root@redis1 lib]# scp /usr/local/tomcat/conf/context.xml 10.0.0.28:/usr/local/tomcat/conf/context.xml
[root@redis1 lib]# systemctl restart tomcat
