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
1 2 | getent group tomcat || groupadd -r tomcat getent passwd tomcat || useradd -r -d /opt -s /bin/nologin tomcat |
3、下载tomcat 7
1 2 3 4 5 6 7 8 9 | cd /opt wget http://mirrors.ustc.edu.cn/apache/tomcat/tomcat-7/v7.0.64/bin/apache-tomcat-7.0.64.tar.gz tar zxvf apache-tomcat-7.0.64.tar.gz mv apache-tomcat-7.0.64 tomcat01 chown -R tomcat:tomcat tomcat01 tar zxvf apache-tomcat-7.0.64.tar.gz mv apache-tomcat-7.0.64 tomcat02 chown -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.
1 2 3 4 | sed -i 's/8080/8081/g' /opt/tomcat01/conf/server.xml sed -i 's/8005/8001/g' /opt/tomcat01/conf/server.xml sed -i 's/8080/8082/g' /opt/tomcat02/conf/server.xml sed -i 's/8005/8002/g' /opt/tomcat02/conf/server.xml |
AJP通常用不上，这里统一关闭
1 2 | sed -i '/8009/d' /opt/tomcat01/conf/server.xml sed -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。
1 2 | sed -i.bak 's#HTTP/1.1#org.apache.coyote.http11.Http11NioProtocol#' /opt/tomcat01/conf/server.xml sed -i.bak 's#HTTP/1.1#org.apache.coyote.http11.Http11NioProtocol#' /opt/tomcat02/conf/server.xml |
3、创建启动文件
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | cd /usr/lib/systemd/system cat >tomcat01.service <<EOF [Unit] Description=Apache Tomcat 7 After=network.target [Service] Type=oneshot ExecStart=/opt/tomcat01/bin/startup.sh ExecStop=/opt/tomcat01/bin/shutdown.sh RemainAfterExit=yes User=tomcat Group=tomcat [Install] WantedBy=multi-user.target EOF |
tomcat02同理
1 | sed 's/tomcat01/tomcat02/g' tomcat01.service > tomcat02.service |
4、启动服务
1 2 3 4 | systemctl enable tomcat01 systemctl enable tomcat02 systemctl start tomcat01 systemctl start tomcat02 |
5、查看进程
1 | ps aux |grep tomcat |
附上一份nginx反向代理tomcat的配置文件
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 | proxy_cache_path /var/cache/nginx/proxy_cache levels=1:2 keys_zone=static:10m inactive=30d 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 7d; 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; } } |
