這篇文章主要講解了“centos7下安裝tomcat并用systemd實(shí)現(xiàn)tomcat多實(shí)例配置方法”,文中的講解內(nèi)容簡單清晰,易于學(xué)習(xí)與理解,下面請大家跟著小編的思路慢慢深入,一起來研究和學(xué)習(xí)“centos7下安裝tomcat并用systemd實(shí)現(xiàn)tomcat多實(shí)例配置方法”吧!
本文我們分享在Centos安裝tomcat,然后用systemd實(shí)現(xiàn)tomcat多實(shí)例的方法,有需求的朋友可以認(rèn)真參考一下。
系統(tǒng)環(huán)境: CentOS 7 x86_64
1、安裝jdk
rpm -ivh jdk-8u60-linux-x64.rpm
2、創(chuàng)建普通用戶
getent group tomcat || groupadd -r tomcat
getent passwd tomcat || useradd -r -d /opt -s /bin/nologin tomcat
3、下載tomcat 7
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
兩個實(shí)例同時(shí)監(jiān)聽8080端口必然會產(chǎn)生沖突,所以必須修改.
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,這里統(tǒng)一關(guān)閉
sed -i '/8009/d' /opt/tomcat01/conf/server.xml
sed -i '/8009/d' /opt/tomcat01/conf/server.xml
tomcat在Linux 下默認(rèn)工作模式是bio,性能非常低,建議使用apr或者nio,
這里改為nio,即非阻塞IO,性能比較好。
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
4、創(chuàng)建啟動文件
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
sed 's/tomcat01/tomcat02/g' tomcat01.service > tomcat02.service
5、啟動服務(wù)
systemctl enable tomcat01
systemctl enable tomcat02
systemctl start tomcat01
systemctl start tomcat02
6、查看進(jìn)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;
