• server1配置tomcat

編輯java文件進行環境測試

測試——訪問172.25.54.9:8080

[root@server1 ROOT]# vim test.jsp [root@server1 ROOT]# cat test.jsp The time is: <%=new java.util.Date() %> [root@server1 ROOT]# cd /usr/local/lnmp/nginx/conf/ [root@server1 conf]# vim nginx.conf59 location ~ \.jsp$ {60 proxy_pass http://127.0.0.1:8080;61 } [root@server1 conf]# nginx -s reload

同樣，需要在server2上配置tomcat

[root@server2 ~]# ls apache-tomcat-7.0.37.tar.gz jdk-7u79-linux-x64.tar.gz [root@server2 ~]# vim /etc/profile [root@server2 ~]# cat /etc/profile |tail -n 3 export JAVA_HOME=/usr/local/java export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib export PATH=$PATH:$JAVA_HOME/bin [root@server2 ~]# source /etc/profile [root@server2 ~]# tar zxf jdk-7u79-linux-x64.tar.gz -C /usr/local/ [root@server2 ~]# tar zxf apache-tomcat-7.0.37.tar.gz -C /usr/local/ [root@server2 ~]# cd /usr/local/ [root@server2 local]# ls apache-tomcat-7.0.37 etc include lib libexec share bin games jdk1.7.0_79 lib64 sbin src [root@server2 local]# ln -s jdk1.7.0_79/ java [root@server2 local]# ln -s apache-tomcat-7.0.37/ tomcat [root@server2 local]# cd tomcat/ [root@server2 tomcat]# bin/startup.sh Using CATALINA_BASE: /usr/local/tomcat Using CATALINA_HOME: /usr/local/tomcat Using CATALINA_TMPDIR: /usr/local/tomcat/temp Using JRE_HOME: /usr/local/java Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar Tomcat started. [root@server2 tomcat]#

測試：

測試——刷新一次需要重新連接一次

[root@server1 ROOT]# pwd /usr/local/tomcat/webapps/ROOT [root@server1 ROOT]# cd /usr/local/tomcat/logs/ [root@server1 logs]# cat catalina.out | tail -n 4 INFO: Starting ProtocolHandler ["ajp-bio-8009"] Aug 07, 2018 10:02:00 AM org.apache.catalina.startup.Catalina start INFO: Server startup in 18610 ms user2 = 234 [root@server1 logs]# [root@server2 ROOT]# pwd /usr/local/tomcat/webapps/ROOT [root@server2 ROOT]# cd /usr/local/tomcat/logs/ [root@server2 logs]# cat catalina.out | tail -n 4 Aug 07, 2018 10:40:11 AM org.apache.catalina.startup.Catalina start INFO: Server startup in 30301 ms user1 = 123 user3 = 345 [root@server2 logs]#

添加sticky函數

• 添加該函數后，不會存在刷新需要重新連接的問題，不過還是存在存儲的問題

[root@server1 ~]# ls apache-tomcat-7.0.90.tar.gz nginx-1.10.1.tar.gz cmake-2.8.12.2-4.el6.x86_64.rpm nginx-sticky-module-ng Discuz_X3.2_SC_UTF8.zip nginx-sticky-module-ng.tar.gz gd-devel-2.0.35-11.el6.x86_64.rpm openresty-1.13.6.1 jdk-7u79-linux-x64.tar.gz openresty-1.13.6.1.tar.gz libmcrypt-2.5.8-9.el6.x86_64.rpm package.xml libmcrypt-devel-2.5.8-9.el6.x86_64.rpm php-5.6.35 memcache-2.2.5 php-5.6.35.tar.bz2 memcache-2.2.5.tgz re2c-0.13.5-1.el6.x86_64.rpm mysql-5.7.11 test.class mysql-boost-5.7.11.tar.gz test.java nginx-1.10.1 [root@server1 ~]# nginx -s stop [root@server1 ~]# cd nginx-1.10.1 [root@server1 nginx-1.10.1]# make clean rm -rf Makefile objs [root@server1 nginx-1.10.1]# ./configure --prefix=/usr/local/lnmp/nginx/ --with-http_ssl_module --with-http_stub_status_module --with-file-aio --with-threads --add-module=/root/nginx-sticky-module-ng //添加sticky函數模塊 [root@server1 nginx-1.10.1]# make && make install [root@server1 nginx-1.10.1]# nginx [root@server1 nginx-1.10.1]# cd /usr/local/lnmp/nginx/conf/ [root@server1 conf]# vim nginx.conf19 upstream tomcat {20 sticky;21 server 172.25.54.4:8080;22 server 172.25.54.9:8080;23 } [root@server1 conf]# nginx -s reload

server1、server2均需要安裝memcached

yum install -y memcached 解決存儲問題
