隨著項(xiàng)目發(fā)展, 需要將一個應(yīng)用部署到多個環(huán)境上, 因?yàn)殛P(guān)系tomcat版本統(tǒng)一, 所以需要同一個tomcat下將一個應(yīng)用部署到不同的端口, 這些應(yīng)用連接不同數(shù)據(jù)庫, 這里使用了tomcat多實(shí)例的方式. 利用tomcat環(huán)境變量CATALINA_BASE, 一共兩個環(huán)境:
- 開發(fā)環(huán)境 連接開發(fā)庫
- 測試環(huán)境 連接測試庫
首先準(zhǔn)備兩個環(huán)境的實(shí)例目錄
開發(fā)環(huán)境: multi-instance/dev
測試環(huán)境: multi-instance/test
兩個實(shí)例目錄都包含以下目錄:
- bin 存放腳本 一般是啟動腳本
- conf 實(shí)例配置文件, 復(fù)制 ${CATALINA_HOME}/conf 修改server.xml文件端口 注意SHUTDOWN 端口多個實(shí)例不能重復(fù)
- logs 實(shí)例日志
- temp
- webapps 實(shí)例運(yùn)行應(yīng)用
- work jsp等編譯后的class文件
然后在 jenkins構(gòu)建項(xiàng)目完成后, 將運(yùn)行文件復(fù)制到對應(yīng)實(shí)例的 webapps目錄下, 在這里之前刪除 之前部署應(yīng)用的文件
啟動腳本大致如下:
JAVA_HOME=/home/crt/jdk/jdk1.7.0_79
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
export CATALINA_BASE="$dev_home"
export CATALINA_HOME="/home/crt/tomcat/apache-tomcat-7.0.72"
echo "開始重啟開發(fā)環(huán)境[CATALINA_BASE=$CATALINA_BASE]::::::::::::::::::::::::::::::::::::::::::"
${CATALINA_HOME}/bin/startup.sh
開發(fā)環(huán)境啟動完整腳本:
