Nginx+Tomcat集群會(huì)話共享 redis cluster
session測(cè)試代碼用例
1.配置虛擬主機(jī)
[root@web01 conf]# vim /soft/tomcat/conf/server.xml
<!--session站點(diǎn)-->
<Host name="session.oldxu.com" appBase="/code/session"
unpackWARs="true" autoDeploy="true">
</Host>
2.準(zhǔn)備index.jsp文件(為了區(qū)分需要調(diào)整輸出的web01 web02)
[root@web01 conf]# cat /code/session/ROOT/index.jsp
<body>
<%
//HttpSession session = request.getSession(true);
System.out.println(session.getCreationTime());
out.println("<br> web01 SESSION ID:" + session.getId() + "<br>");
out.println("Session created time is :" + session.getCreationTime()
+ "<br>");
%>
</body>
3.下載TomcatClusterRedisSessionManager (所有web集群都需要操作)
[root@tomcat ~]# wget https://github.com/ran-jit/tomcat-cluster-redis-session-manager/releases/download/3.0.3/tomcat-cluster-redis-session-manager.zip
[root@tomcat ~]# unzip tomcat-cluster-redis-session-manager.zip
[root@web01 ~]# cd tomcat-cluster-redis-session-manager
4.拷貝jar包
[root@web01 tomcat-cluster-redis-session-manager]# cp lib/* /soft/tomcat/lib/
5.拷貝tomcat連接redis配置文件
[root@web01 tomcat-cluster-redis-session-manager]# cp conf/redis-data-cache.properties /soft/tomcat/conf/
6.修改redis-data-cache.properties
[root@web01 ~]# vim /soft/tomcat/conf/redis-data-cache.properties
...
redis.hosts=172.16.1.51:6379
redis.password=123456 #有密碼就寫(xiě)密碼,沒(méi)有不要寫(xiě)
...
7.添加如下兩行至tomcat/conf/context.xml
[root@web01 ~]# vim /soft/tomcat/conf/context.xml
<Context>
.....
<Valve className="tomcat.request.session.redis.SessionHandlerValve" />
<Manager className="tomcat.request.session.redis.SessionManager" />
....
</Context>
8.修改tomcat/conf/web.xml 配置文件session的超時(shí)時(shí)間 ,單位是分鐘
<session-config>
<session-timeout>60</session-timeout> #根據(jù)情況調(diào)整
</session-config>
9.安裝redis，當(dāng)然也可以自行搭建redis集群，anyway
[root@redis ~]# yum install redis -y
[root@redis ~]# cat /etc/redis.conf
...
bind 172.16.1.51 127.0.0.1
requirepass 123456 #如果不需要密碼,則不要配置
...
[root@redis ~]# systemctl start redis
[root@redis ~]# systemctl enable redis
10.重啟多臺(tái)機(jī)器的Tomcat
11.接入負(fù)載均衡,通過(guò)負(fù)載均衡輪詢調(diào)度檢查是否正常
12.如果session會(huì)話不正常:
將域名解析到指定的服務(wù)器,通過(guò)8080的方式去訪問(wèn),測(cè)試,檢查日志.
Nginx+Tomcat集群全站Https
單臺(tái):
1.http接收器修改為 80端口 ---> 443
2.配置443的證書(shū)
集群:
[root@lb01 conf.d]# cat proxy_zrlog.oldxu.com.conf
upstream zrlog {
server 172.16.1.7:8080;
server 172.16.1.8:8080;
}
server {
listen 443 ssl;
ssl_certificate ssl_key/server.crt;
ssl_certificate_key ssl_key/server.key;
server_name zrlog.oldxu.com;
location / {
proxy_pass http://zrlog;
include proxy_params;
}
}
server {
listen 80;
server_name zrlog.oldxu.com;
return 302 https://$http_host$request_uri;
}
