环境: CentOS 7 x86_64 1、安装jdk 1 rpm -ivh jdk-8u60-linux-x64.rpm 2、创建普通用户 12 getent group tomcat || groupadd -r tomcatgetent passwd tomcat || useradd -r -d /opt -s /bin/nologin tomcat 3、下载tomcat 7 123456789 cd /optwget http://mirrors.ustc.edu.cn/<a href="http://so.21ops.com/cse/search?s=9181936462520079739&entry=1&q=apache" class="bdcs-inlinelink"target="_blank">apache</a>/tomcat/tomcat-7/v7.0.64/bin/apache-tomcat-7.0.64.tar.gztar zxvf apache-tomcat-7.0.64.tar.gzmv apache-tomcat-7.0.64 tomcat01chown -R tomcat:tomcat tomcat01 tar zxvf apache-tomcat-7.0.64.tar.gzmv apache-tomcat-7.0.64 tomcat02chown -R tomcat:tomcat tomcat02 两个实例同时监听8080端口必然会产生冲突，所以必须修改. 1234 sed -i 's/8080/8081/g' /opt/tomcat01/conf/server.xmlsed -i 's/8005/8001/g' /opt/tomcat01/conf/server.xmlsed -i 's/8080/8082/g' /opt/tomcat02/conf/server.xmlsed -i 's/8005/8002/g' /opt/tomcat02/conf/server.xml AJP通常用不上，这里统一关闭 12 sed -i '/8009/d' /opt/tomcat01/conf/server.xmlsed -i '/8009/d' /opt/tomcat01/conf/server.xml tomcat在Linux 下默认工作模式是bio,性能非常低,建议使用apr或者nio， 这里改为nio,即非阻塞IO,性能比较好。 12 sed -i.bak 's#HTTP/1.1#org.apache.coyote.http11.Http11NioProtocol#' /opt/tomcat01/conf/server.xmlsed -i.bak 's#HTTP/1.1#org.apache.coyote.http11.Http11NioProtocol#' /opt/tomcat02/conf/server.xml 3、创建启动文件 123456789101112131415 cd /usr/lib/systemd/systemcat >tomcat01.service <<EOF[Unit]Description=Apache Tomcat 7After=network.target[Service]Type=oneshotExecStart=/opt/tomcat01/bin/startup.shExecStop=/opt/tomcat01/bin/shutdown.shRemainAfterExit=yesUser=tomcatGroup=tomcat[<a href="http://so.21ops.com/cse/search?s=9181936462520079739&entry=1&q=Install"class="bdcs-inlinelink" target="_blank">Install</a>]WantedBy=multi-user.targetEOF tomcat02同理 1 sed 's/tomcat01/tomcat02/g' tomcat01.service > tomcat02.service 4、启动服务 1234 systemctl enable tomcat01systemctl enable tomcat02systemctl start tomcat01systemctl start tomcat02 5、查看进程 ps aux |grep tomcat 附上一份nginx反向代理tomcat的配置文件 proxy_cache_path /var/cache/nginx/proxy_cache levels=1:2 keys_zone=static:10m inactive=1h max_size=1g; upstream tomcat { ip_hash ; #hash $remote_addr consistent; server 127.0.0.1:8081 max_fails=1 fail_timeout=2s ; server 127.0.0.1:8082 max_fails=1 fail_timeout=2s ; ; keepalive 16; } server { listen 80; server_name tomcat.example.com; charset utf-8; access_log /var/log/nginx/tomcat.access.log main; root /usr/share/nginx/html; index index.html index.htm index.jsp; location / { proxy_pass http://tomcat; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_503 http_504; proxy_connect_timeout 300; proxy_send_timeout 300; proxy_read_timeout 300; proxy_http_version 1.1; proxy_set_header Connection ""; add_header X-Backend "$upstream_addr"; } location ~* ^.+.(js|css|ico|gif|jpg|jpeg|png)$ { proxy_pass http://tomcat ; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_503 http_504; proxy_connect_timeout 300; proxy_send_timeout 300; proxy_read_timeout 300; proxy_http_version 1.1; proxy_set_header Connection ""; proxy_cache static; proxy_cache_key $host$uri$is_args$args; proxy_cache_valid 200 302 5m; proxy_cache_valid 404 1m; proxy_cache_valid any 1h; add_header X-Cache $upstream_cache_status; #log_not_found off; #access_log off; expires max; } location ~ /.ht { deny all; } } (责任编辑：IT) |
