#yum -y install java-1.8.0-openjdk

rpm源碼包安裝：

#rpm -ivh xxx

編譯安裝：

#tar zxvf xxx -C /root/

#cd ?/root/xx

#cp -rp jre1.7.-_05 /usr/local

#vi /etc/profile????????配置全局環境

JAVA_HOME=/usr/local/xxx

CLASSPATH=$CLASSPATH:$JAVA_HOME/lib

PATH=$JAVA_HOME/bin:$PATH

測試java是否安裝成功

#chown -R root.root /usr/local/xxx/

#java -version

如果運行java報錯：

error :/usr/lib/libjvm.so: cannot restore segment prot after reloc: Permission denied .use the command:chcon -t textrel_shlib_t /usr/lib/libjvm.so

是selinux導致的

#setenforce 0

二、安裝tomcat7

#tar zxvf xxx????解壓之后就是二進制文件，無需安裝。直接將目錄移動到/usr/local目錄即可

#mv xxx /usr/local/tomcat

#vim /usr/local/tomcat/bin/catalisna.sh????在tomcat啟動腳本中設置環境變量

JAVA_HOME=/usr/java/jdk1.8.0xx????????????使其支持java，添加此行

#vim /etc/profile

CATALINA_HOME=/usr/local/tomcat/

PATH=$JAVA_HOME/bin:/usr/local/tomcat/bin/:$PATH????? ? 設置環境變量

退出當前shell，重進后該配置生效

or

#. /etc/profile????使新的環境變量生效

手動啟動/關閉/重啟tomcat

#/usr/local/tomcat/bin/catalina.sh

#netstat -lnp |grep 80????發現80開頭的端口，即表示tomcat啟動成功

#/usr/local/tomcat/bin/catalina.sh stop/restart

#/usr/local/tomcat/bin/shutdown.sh????也可以關閉tomcat

設置systemctl開機自啟動服務

#vim /lib/systemd/system/tomcat.service

[Unit]

Description=tomcat

After=network.target

[Service]

Type=forking

ExecStart=/usr/local/tomcat/bin/catalina.sh start

ExecReload=/usr/local/tomcat/bin/catalina.sh restart

ExecStop=/usr/local/tomcat/bin/catalina.sh ?stop

PrivateTmp=true

[Install]

WantedBy=multi-user.target

#systemctl enable tomcat.service????鏈接到systemctl開機自啟動服務

#systemctl start/stop/restart tomcat.service

三、tomcat+apache整合

整合方式三種：

01 JK方式

02 http_proxy方式

03 ajp_proxy方式

http_proxy方式需要的模塊：

mod_proxy.so和mod_prxy_http.so

默認mod_proxy.so已經安裝，只需安裝mod_proxy_http.so模塊

#ls /usr/lib64/httpd/modules/mod_proxy_http.so

#ls /usr/lib64/httpd/modules/mod_proxy.so

將該模塊添加到httpd.conf配置文件中

#vim /etc/httpd/conf/httpd.conf

LoadModule??proxy_http_module modules/mod_proxy_http.so

#service httpd restart?????重啟apache服務
