????????在同一機(jī)器中運(yùn)行多個(gè)Tomcat時(shí)，如果不修改server.xml的端口參數(shù)，會(huì)出現(xiàn)端口沖突使得Tomcat異常；Tomcat默認(rèn)配置中，JAVA_OPTS不會(huì)設(shè)置太大，一般需要在catalina.sh中增加一行配置來(lái)加大該參數(shù)值。

1.Server.xml配置

????????需要改動(dòng)的端口為：Server標(biāo)簽、HTTP的Connector標(biāo)簽和AJP的Connector標(biāo)簽。

xml如下：

<?xml version="1.0" encoding="UTF-8"?><Server port="8001" shutdown="SHUTDOWN"><Listener className="org.apache.catalina.startup.VersionLoggerListener" /><Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" /><Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" /><Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" /><Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" /><!-- Global JNDI resourcesDocumentation at /docs/jndi-resources-howto.html--><GlobalNamingResources><!-- Editable user database that can also be used byUserDatabaseRealm to authenticate users--><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 port="8088" protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443" /><!-- Define an AJP 1.3 Connector on port 8009 --><Connector protocol="AJP/1.3"address="::1"port="8009"redirectPort="8443" /><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="webapps"unpackWARs="true" autoDeploy="true"><Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"prefix="localhost_access_log" suffix=".txt"pattern="%h %l %u %t &quot;%r&quot; %s %b" /></Host></Engine></Service>
</Server>

2.Catalina.sh配置

? ? ? ? 在sh文件首行加上JAVA_OPTS="-Xms4096M -Xmx8192M"這一行。

本文介紹了Tomcat的一些使用注意事項(xiàng)，記錄一下。
