一、安裝
1.安裝JDK
下載的jdk文件為：jdk-6u45-linux-x64.bin，執(zhí)行如下命令進(jìn)行安裝：
#./jdk-6u12-linux-i586.bin
2.安裝tomcat：
#tar zxvf apache-tomcat-6.0.18.tar.gz#mv apache-tomcat-6.0.29 tomcat
這里我將解壓后的apache-tomcat-6.0.29重命名為了tomcat方便操作。
3.配置環(huán)境變量：
編輯/etc下的profile文件，加上如下內(nèi)容：
JAVA_HOME="/opt/app/jdk1.6.0_45"CLASS_PATH="$JAVA_HOME/lib:$JAVA_HOME/jre/lib"PATH=".:$PATH:$JAVA_HOME/bin"CATALINA_HOME="/opt/app/tomcat"export JAVA_HOME CATALINA_HOME
執(zhí)行下面命令使變更生效：
# source /etc/profile
啟動(dòng)tomcat并輸入http://domain:8080，如果看到貓的頁(yè)面即tomcat和jdk安裝成功
新建文件目錄/home/www為網(wǎng)站存放目錄，設(shè)置server.xml文件，在Host name=”localhost”處將appBase=的指向路徑改為/home/www/web
創(chuàng)建index.jsp至/home/www/web/ROOT，內(nèi)容為：“hello!” 重新啟動(dòng)tomcat，重新訪問，如果看到index.jsp文件內(nèi)容hello！表示設(shè)置成功。
4.安裝Nginx
執(zhí)行如下命令解壓nginx：
# tar zxvf nginx-1.4.4.tar.gz# mv nginx-1.4.4 nginx
同樣重命名了一下。
安裝nginx：
# ./configure --prefix=/opt/app/nginx
結(jié)果出現(xiàn)了錯(cuò)誤：error: C compiler cc is not found，按網(wǎng)上所說(shuō)安裝編譯源碼所需的工具和庫(kù)：
#yum install gcc gcc-c++ ncurses-devel perl
再次安裝，發(fā)現(xiàn)還有錯(cuò)誤：the HTTP rewrite module requires the PCRE library.
執(zhí)行
# yum -y install pcre-devel openssl openssl-devel
終于成功，
# ./configure --prefix=/opt/app/nginx# make# make install
nginx安裝成功后的安裝目錄為/opt/app/nginx
二、Nginx方面的配置
在/usr/local/目錄下分別安裝nginx和tomcat
為nginx添加conf.d目錄，用于各項(xiàng)目的配置，比如新建renhetoutiao.conf文件
server { listen 80; server_name devtoutiao.renhe.cn; root /home/renhetoutiao/renhetoutiao/htdocs; access_log /home/renhetoutiao/renhetoutiao/logs/access_log.log; location = / { rewrite ^/$ /index.shtml last; } location ~ .shtml { proxy_pass http://localhost:8081; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location ~ .*.(js|css)?$ { expires 1h; }}server { listen 80; server_name devtoutiao.renhe.cn; root /home/renhetoutiao/renhetoutiao/htdocs; access_log /home/renhetoutiao/renhetoutiao/logs/access_log.log; location = / { rewrite ^/$ /index.shtml last; } location ~ .shtml { proxy_pass http://localhost:8081; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location ~ .*.(js|css)?$ { expires 1h; }} 對(duì)nginx的conf/nginx.conf修改，第二行 user root，賦予nginx root權(quán)限，在http中添加 include /usr/local/nginx/conf.d/*.conf;
選擇一個(gè)項(xiàng)目如renhetoutiao, 目錄/home/renhetoutiao/renhetoutiao/
三、Tomcat方面的配置
catalina.policy catalina.properties context.xml tomcat-users.xml server.xml web.xml
這5個(gè)配置文件就可以啟動(dòng)一個(gè)tomcat實(shí)例，其中server.xml是必須配置的。
catalina.policy catalina.properties web.xml 可以使用默認(rèn)的，可以從安裝路徑copy,context.xml tomcat-users.xml可以不用。
所以每個(gè)項(xiàng)目我們只需要配置server.xml, 如renhetoutiao項(xiàng)目的配置
<?xml version='1.0' encoding='utf-8'?><Server port="8015" shutdown="SHUTDOWN"> <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" /> <Listener className="org.apache.catalina.core.JasperListener" /> <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" /> <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" /> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" /> <Service name="Catalina"> <Connector port="8081" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> <Engine name="Catalina" defaultHost="localhost"> <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="false" xmlValidation="false" xmlNamespaceAware="false"> <Context docBase="/home/renhetoutiao/renhetoutiao/web" path="" /> </Host> </Engine> </Service></Server><?xml version='1.0' encoding='utf-8'?><Server port="8015" shutdown="SHUTDOWN"> <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" /> <Listener className="org.apache.catalina.core.JasperListener" /> <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" /> <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" /> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" /> <Service name="Catalina"> <Connector port="8081" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> <Engine name="Catalina" defaultHost="localhost"> <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="false" xmlValidation="false" xmlNamespaceAware="false"> <Context docBase="/home/renhetoutiao/renhetoutiao/web" path="" /> </Host> </Engine> </Service></Server>
因?yàn)槭褂胣ginx，tomcat的ajp不會(huì)使用，所以可以去掉，tomcat可以這樣簡(jiǎn)單配置。注意每個(gè)項(xiàng)目的連接端口和關(guān)閉端口，不要有重復(fù)。
因?yàn)閠omcat回去加載指定路徑下得class lib，所以必須把配置、依賴等copy至web下，啟動(dòng)腳本bin/startup，關(guān)閉腳本bin/shutdown 如下:
#!/bin/sh export CATALINA_BASE="$PWD"export CATALINA_HOME="/usr/local/tomcat" #啟動(dòng)為適配tomcat目錄做的準(zhǔn)備#遷移tomcat必要的配置文件 catalina.policy catalina.properties context.xml tomcat-users.xml web.xmlif [ ! -f "$CATALINA_BASE"/conf/catalina.policy ]; then cp "$CATALINA_HOME"/conf/catalina.policy "$CATALINA_BASE"/conffi if [ ! -f "$CATALINA_BASE"/conf/catalina.properties ]; then cp "$CATALINA_HOME"/conf/catalina.properties "$CATALINA_BASE"/conffi if [ ! -f "$CATALINA_BASE"/conf/web.xml ]; then cp "$CATALINA_HOME"/conf/web.xml "$CATALINA_BASE"/conffi if [ ! -d "$CATALINA_BASE"/logs ]; then mkdir logsfi #準(zhǔn)備classes和lib目錄CLASSES_PATH="$CATALINA_BASE"/web/WEB-INF/classesLIB_PATH="$CATALINA_BASE"/web/WEB-INF/librm -rf "$CLASSES_PATH"rm -rf "$LIB_PATH"cp -R "$CATALINA_BASE"/conf "$CLASSES_PATH"cp -R "$CATALINA_BASE"/lib "$LIB_PATH" #啟動(dòng)時(shí)會(huì)記錄進(jìn)程ID，存放于logs/tomcat.pid內(nèi)#shutdown時(shí)強(qiáng)制關(guān)閉該進(jìn)程$CATALINA_HOME/bin/startup.sh
#!/bin/sh export CATALINA_BASE="$PWD"export CATALINA_HOME="/usr/local/tomcat" #啟動(dòng)為適配tomcat目錄做的準(zhǔn)備#遷移tomcat必要的配置文件 catalina.policy catalina.properties context.xml tomcat-users.xml web.xmlif [ ! -f "$CATALINA_BASE"/conf/catalina.policy ]; then cp "$CATALINA_HOME"/conf/catalina.policy "$CATALINA_BASE"/conffi if [ ! -f "$CATALINA_BASE"/conf/catalina.properties ]; then cp "$CATALINA_HOME"/conf/catalina.properties "$CATALINA_BASE"/conffi if [ ! -f "$CATALINA_BASE"/conf/web.xml ]; then cp "$CATALINA_HOME"/conf/web.xml "$CATALINA_BASE"/conffi if [ ! -d "$CATALINA_BASE"/logs ]; then mkdir logsfi #準(zhǔn)備classes和lib目錄CLASSES_PATH="$CATALINA_BASE"/web/WEB-INF/classesLIB_PATH="$CATALINA_BASE"/web/WEB-INF/librm -rf "$CLASSES_PATH"rm -rf "$LIB_PATH"cp -R "$CATALINA_BASE"/conf "$CLASSES_PATH"cp -R "$CATALINA_BASE"/lib "$LIB_PATH"#啟動(dòng)時(shí)會(huì)記錄進(jìn)程ID，存放于logs/tomcat.pid內(nèi)#shutdown時(shí)強(qiáng)制關(guān)閉該進(jìn)程$CATALINA_HOME/bin/startup.sh
#!/bin/sh export CATALINA_BASE="$PWD"export CATALINA_HOME="/usr/local/tomcat" $CATALINA_HOME/bin/shutdown.sh#!/bin/sh export CATALINA_BASE="$PWD"export CATALINA_HOME="/usr/local/tomcat" $CATALINA_HOME/bin/shutdown.sh
通過tomcat的startup.sh腳本,會(huì)碰到項(xiàng)目中分配的線程沒有及時(shí)釋放，tomcat不能及時(shí)關(guān)閉，導(dǎo)致重啟時(shí)產(chǎn)生端口沖突
解決方案：強(qiáng)制關(guān)閉tomcat進(jìn)程，kill -9 PID，執(zhí)行腳本需要啟動(dòng)時(shí)記錄各個(gè)tomcat實(shí)例的進(jìn)程，這里將進(jìn)程PID保存在項(xiàng)目的logs目錄下。
記錄PID的操作需要修改tomcat安裝目錄下 bin/catalina.sh腳本
在PRGDIR=dirname "$PRG"后面加上
TOMCAT_PID="$PWD"/"logs/tomcat.pid"if [ -f "$TOMCAT_PID" ]; then CATALINA_PID="$TOMCAT_PID"elif [ $1 = "start" ]; then CATALINA_PID="$TOMCAT_PID"fiTOMCAT_PID="$PWD"/"logs/tomcat.pid"if [ -f "$TOMCAT_PID" ]; then CATALINA_PID="$TOMCAT_PID"elif [ $1 = "start" ]; then CATALINA_PID="$TOMCAT_PID"fi
最后需要給項(xiàng)目用戶可執(zhí)行權(quán)限 chmod 777 catalina.sh
