linux下简洁优化部署tomcat应用
本文来自我的github pages博客http://galengao.github.io/ 即www.gaohuirong.cn
摘要:
- 本文是自己根据公司架构部署tomcat方法整理出来的文本
修改系统内核
修改linux的一些系统参数，以优化系统性能
- 修改LIMITS.CONF
$ vi /etc/security/limits.conf # 增加 * soft nofile 65536 * hard nofile 65536
- 修改SYSCTL.CONF
# 备份 $ mv /etc/sysctl.conf /etc/sysctl.conf.bak $ vi /etc/sysctl.conf # 插入 net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 net.ipv4.tcp_max_tw_buckets = 6000 net.ipv4.tcp_sack = 1 net.ipv4.tcp_window_scaling = 1 net.ipv4.tcp_rmem = 4096 87380 4194304 net.ipv4.tcp_wmem = 4096 16384 4194304 net.core.wmem_default = 8388608 net.core.rmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.core.netdev_max_backlog = 262144 net.core.somaxconn = 262144 net.ipv4.tcp_max_orphans = 3276800 net.ipv4.tcp_max_syn_backlog = 262144 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_synack_retries = 1 net.ipv4.tcp_syn_retries = 1 net.ipv4.tcp_tw_recycle = 1 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_mem = 94500000 915000000 927000000 net.ipv4.tcp_fin_timeout = 1 net.ipv4.tcp_keepalive_time = 30 net.ipv4.ip_local_port_range = 1024 65000
安装APR
- 下载apr-1.5.2.tar.gz和apr-util-1.5.4.tar.gz
安装apr，方便tomcat 开启aoi
apr下载地址
$ tar -zxvf apr-1.5.2.tar.gz $ tar -zxvf apr-util-1.5.4.tar.gz $ yum install gcc gcc-c++ autoconf libtool # apr安装 $ cd apr-1.5.2 $ ./configure --prefix=/usr/local/apr # --prefix=/usr/local/apr指apr的安装路径，以下要用到 $ make $ make install # apr-util安装 $ cd apr-util-1.5.4 $ ./configure --with-apr=/usr/local/apr # --with-apr=/usr/local/apr 指定APR安装路径 $ make $ make install
安装JDK1.7
下载jdk-7u76-linux-x64.tar.gz 拷贝到/usr/local下面
cd /usr/local $ tar -zxvf jdk-7u76-linux-x64.tar.gz # mv 重命名 为jdk1.7.0_76 mv jdk1.7.0_76 jdk1.7 # 在环境变量/etc/profile里配置JAVA_HOME JAVA_HOME=/usr/local/jdk1.7 PATH=$PATH:$HOME/bin:$JAVA_HOME/bin CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME PATH CLASSPATH # 环境变量立即生效 $ source .bash_profile
编译安装tomcat
创建DATA目录
$ mkdir /data
复制TOMCAT到目标目录并解压
$ cp apache-tomcat-7.0.64.tar.gz /data $ tar -zxvf apache-tomcat-7.0.64.tar.gz # mv 重命名为你所需的项目名称，如zhnx $ mv apache-tomcat-7.0.64 zhnx
进入TOMCAT精简目录
请参照下面步骤一步一步顺序操作
$ cd zhnx # 把项目除了bin lib conf目录的其它全部删除 $ rm -rf LICENSE logs NOTICE RELEASE-NOTES RUNNING.txt temp/webapps/work/ # 在同目录新建三个文件夹domain、server、sbin $ mkdir domain $ mkdir server $ mkdir sbin # 把bin 和lib目录移动到server下面 $ mv bin/ server/ $ mv lib/ server/ # 把conf目录移动到domain下面 $ mv conf/ domain/ # 安装tomcat native 开启aio # 进入server/bin目录下安装tomcat native 与apr连起来 开启tomcat aio模式 $ cd server/bin # 解压 tomcat native $ tar -zxvf tomcat-native.tar.gz # 进入安装tomcat native目录 $ cd tomcat-native-1.1.33-src $ cd jni $ cd native # 执行命令 $ ./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/jdk1.7.0_76 $ make $ make install # 创建项目目录(这里项目名称示例CENTER） $ cd /data/zhnx/domain $ mkdir center # 把conf目录移动到项目下 $ mv conf/ center/
拷贝并修改脚本启动参数
- 到目录/data/zhnx/sbin 下新建三个脚本，这里与center项目为例：startcenter.sh、stopcenter.sh和super.sh
$ cd /data/zhnx/sbin
# 脚本一 $ vi startcenter.sh #!/bin/bash # 下面需要修改的地方 # 1、HOME=/data/zhnx根据自己建的目录 export HOME=/data/zhnx export DOMAIN_HOME=${HOME}/domain export LOG_HOME=${HOME}/logs export TOMCAT_HOME=${HOME}/server #Variable settings begin # 下面需要修改的地方 # 1、export projectName=center 服务名称，即war包名称 # 2、export httpPort=7001 启动接收请求端口端口 # 3、export serverPort=8001 tomcat启动的本地端口 export projectName=center export httpPort=7001 export serverPort=8001 export minMsMem=3200m export maxMsMem=3200m export ssMem=300k export mnMem=1100m export survivorRatior=2 export minPermSize=250m export maxPermSize=300m export threshold=20 export fraction=60 export pageSize=128m export warFile=${HOME}/center_webapps # 服务名加webapps war包地址 export logFile=${LOG_HOME}/${projectName}/catalina.$(date +'%Y-%m-%d').out export pidFile=${LOG_HOME}/${projectName}.pid export LD_LIBRARY_PATH=/usr/local/apr/lib export heapDumpPath=${DOMAIN_HOME}/${projectName}/heapDump #Variable settings end #JVM args settings begin # 下面需要修改的地方： # 1、Dtjtag=center服务名称 CATALINA_OPTS="-server -Dtjtag=center -Dtomcat.server.port=${serverPort} -Dtomcat.http.port=${httpPort} -Dtomcat.deploy.home=${warFile}" CATALINA_OPTS="${CATALINA_OPTS} -Xms${minMsMem} -Xmx${maxMsMem} -Xss${ssMem} -Xmn${mnMem} -XX:SurvivorRatio=${survivorRatior} -XX:PermSize=${minPermSize} -XX:MaxPermSize=${maxPermSize}" CATALINA_OPTS="${CATALINA_OPTS} -XX:+UseCompressedOops -XX:+TieredCompilation -XX:+AggressiveOpts -XX:+UseBiasedLocking" CATALINA_OPTS="${CATALINA_OPTS} -XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -Xnoclassgc -XX:MaxTenuringThreshold=${threshold} -XX:CMSInitiatingOccupancyFraction=${fraction} -XX:LargePageSizeInBytes=${pageSize} -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${heapDumpPath}" #JVM args settings end export CATALINA_BASE=${DOMAIN_HOME}/${projectName} export CATALINA_OPTS export CATALINA_OUT="${logFile}" export CATALINA_PID="${pidFile}" export CATALINA_OPTS ${TOMCAT_HOME}/bin/catalina.sh start exit $?
$ cd /data/zhnx/sbin
# 脚本二 $ vi stopcenter.sh #!/bin/bash # 下面需要修改的地方 # 1、HOME=/data/zhnx根据自己建的目录 # 2、JAVA_HOME=/usr/local/jdk1.7 根据自己JDK的路劲 export HOME=/data/zhnx export JAVA_HOME=/usr/local/jdk1.7 export DOMAIN_HOME=${HOME}/domain export LOG_HOME=${HOME}/logs export TOMCAT_HOME=${HOME}/server export CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar export PATH=${JAVA_HOME}/bin:${PATH} #Variable settings begin # 下面需要修改的地方 # 1、export projectName=center 项目名称，即war包名称 # 2、export serverPort=8001 tomcat本地启动端口，以上面对应 export projectName=center export serverPort=8001 #Variable settings end export JAVA_OPTS="-Dtomcat.server.port=${serverPort}" export CATALINA_PID="${LOG_HOME}/${projectName}.pid" export CATALINA_BASE=${DOMAIN_HOME}/${projectName} ${TOMCAT_HOME}/bin/catalina.sh stop 30 -force exit $?
$ cd /data/zhnx/sbin
# 脚本三 vi super.sh checkProcess(){ pid=`ps -ef|grep ${classname}|grep -v 'grep'|awk '{print $2}'` if [ "X${pid}" != "X" ]; then return 0 else return 1 fi } printStartStatus(){ checkProcess if [ $? -eq 0 ]; then echo "${_moduleName} start sucessful. [OK]" return 0 else echo "${_moduleName} start Failed. [Failed]" return 1 fi } startProcess(){ echo $1 checkProcess if [ $? -eq 0 ]; then echo "${_moduleName} had started." return 0 else ${start} sleep 3 printStartStatus fi } stopProcess(){ echo $1 checkProcess if [ $? -eq 1 ]; then echo "${_moduleName} not running. [FAILED]" else pid=`ps -ef|grep ${classname}|grep -v 'grep'|awk '{print $2}'` if [ "X${pid}" = "X" ]; then echo "${_moduleName} had stop. [OK]" else kill -9 $pid echo "${_moduleName} stop sucessful. [OK]" fi fi } restartProcess(){ stopProcess $1 startProcess $2 } getProcessStatus(){ checkProcess if [ $? -eq 0 ]; then echo "${_moduleName} is running." return 0 else echo "${_moduleName} is not running." return 1 fi } unstall(){ checkProcess if [ $? -eq 0 ]; then pid=`ps -ef|grep ${classname}|grep -v 'grep'|awk '{print $2}'` if [ "X${pid}" != "X" ]; then kill -9 $pid fi fi ${remove} } commandError(){ echo "" echo "ERROR:UNKNOWN COMMAND:\"$_command\" " exit 1 }
- 到目录/etc/rc.d/init.d/下新建一个脚本，这里与center项目为例：center
$ cd /etc/rc.d/init.d/
# 脚本四 $ vi center #!/bin/sh # 下面需要修改的地方 # 1、classname="tjtag=center" center服务名称 # 2、_moduleName="center" modul名称 # 3、start="/data/zhnx/sbin/startcenter.sh" 上面新建的脚本 # 4、. /data/zhnx/sbin/super.sh 上面新建的脚本 classname="tjtag=center" _command=$1 _moduleName="center" start="/data/zhnx/sbin/startcenter.sh" . /data/zhnx/sbin/super.sh case $_command in start) startProcess "Starting ${_moduldName}:" ;; stop) stopProcess "Stoping ${_moduldName}:" ;; restart) restartProcess "Stoping ${_moduldName}:" "Starting ${_moduldName}:" ;; status) getProcessStatus ;; *) commandError ;; esac
删除原始的并替换修改过的SERVER.XML
$ cd /data/zhnx/domain/center/conf $ rm -rf server.xml vi server.xml <?xml version='1.0' encoding='utf-8'?> <Server port="${tomcat.server.port}" shutdown="SHUTDOWN"> <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="off" /> <Listener className="org.apache.catalina.core.JasperListener" /> <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" /> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" /> <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" /> <GlobalNamingResources> <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" /> </GlobalNamingResources> <Service name="Catalina"> <Connector URIEncoding="UTF-8" minSpareThreads="15" maxSpareThreads="30" enableLookups="false" disableUploadTimeout="true" acceptCount="500" maxThreads="50" maxProcessors="1000" minProcessors="10" useURIValidationHack="false" compression="on" compressionMinSize="512" compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain" protocol="org.apache.coyote.http11.Http11AprProtocol" port="${tomcat.http.port}" connectionTimeout="20000"/> <Engine name="Catalina" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.LockOutRealm"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> </Realm> <Host name="localhost" appBase="${tomcat.deploy.home}" unpackWARs="true" autoDeploy="false"> <Context path="" docBase="sso" sessionCookiePath="/" sessionCookieDomain=".qasite.com" useHttpOnly="true" crossContext="true" debug="0" reloadable="false"> <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:192.168.10.11:11220" sticky="false" lockingMode="auto" sessionBackupAsync="false" sessionBackupTimeout="1000" transcoderFactoryClass="de.javakaffee.web.msm.JavaSerializationTranscoderFactory" /> </Context> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> </Host> </Engine> </Service> </Server>
若有自己需要增加的jar就拷进去
$ cd /data/zhnx/server/lib 把jar考进去
项目部署
新建目录webapp名称与startcenter.sh里的webapps名称一样
日志名称与服务名一样
$ mkdir -p /data/zhnx/center_webapps
$ mkdir -p /data/zhnx/logs/center
center.war 部署至 center_webapps
部署时需将对应webapps目录下的文件及文件夹清空；
然后把项目war包拷入对应webapps目录下
启动服务
service center start
