tomcat调优: apr、tomcat-native、JVM、隐藏版本

1.安装apr

tee -a apr.sh <<-'EOF'
#!/bin/bash
export PATH
# Check if user is root
if [ $(id -u) != "0" ]; then
    echo "Error: You must be root to run this script, please use root to optimization system"
    exit 1
fi
#Install gcc
yum install make gcc gcc-c++ wget libtool expat-devel vim -y
#Download apr
wget http://mirror.bit.edu.cn/apache//apr/apr-1.7.0.tar.gz;
wget http://mirror.bit.edu.cn/apache//apr/apr-util-1.6.1.tar.gz;
wget http://mirror.bit.edu.cn/apache//apr/apr-iconv-1.2.2.tar.gz;
#Install apr
tar zxvf apr-1.7.0.tar.gz && cd apr-1.7.0;
sed -i 's/$RM "$cfgfile/#$RM "$cfgfile/g' configure;
./configure --prefix=/usr/local/apr && make && make install && cd ..;
tar zxvf apr-iconv-1.2.2.tar.gz && cd apr-iconv-1.2.2 && ./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr make && make install && cd ..;
tar zxvf apr-util-1.6.1.tar.gz && cd apr-util-1.6.1 && ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr --with-apr-iconv=/usr/local/apr-iconv/bin/apriconv make && make install
EOF

2.本机

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.53/bin/apache-tomcat-8.0.53.tar.gz && tar zxvf apache-tomcat-8.0.53.tar .gz && tar zxvf apache-tomcat-8.0.53 / bin / tomcat-native.tar.gz && cd tomcat-native-1.2.17-src / native / && ./configure --with-apr = / usr / local / apr --with-java-home = / usr / java / jdk1.8.0_181-amd64 && make &&进行安装

如果configure报错配置：错误：您的OpenSSL版本与此tcnative版本不兼容 

wget https://www.openssl.org/source/openssl-1.1.1d.tar.gz&&tar zxvf openssl-1.1.1d.tar.gz && cd openssl-1.1.1d &&。/ config --prefix = / usr / local / openssl -fPIC && make和＆make安装

注意这里需要加入 -fPIC参数，否则后面在安装tomcat native 组件会出错

mv / usr / bin / openssl〜;
ln -s / usr / local / openssl / bin / openssl / usr / bin / openssl;
在-s /usr/local/openssl/lib/libssl.so.1.1 /usr/lib64/libssl.so.1.1;
ln -s /usr/local/openssl/lib/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1;

查看版本

openssl版本

最后再configure

./configure --with-apr = / usr / local / apr --with-java-home = / usr / java / jdk1.8.0_181-amd64 --with-ssl = / usr / local / openssl

配置环境变量

tee-a / etc / profile <<-'EOF'
导出LD_LIBRARY_PATH = / usr / local / apr / lib
紧急行动
源/ etc / profile; 
ln -s /usr/local/apr/lib/libtcnative-1.so /usr/lib64/libtcnative-1.so

3.内存优化JVM

vim apache-tomcat-8.0.53 / bin / catalina.sh

JAVA_OPTS =“-服务器-Xms1024m -Xmx1024m -XX：PermSize = 512M -XX：MaxNewSize = 1024m -XX：MaxPermSize = 512m -XX：MaxDirectMemorySize = 512m -Djava.awt.headless = true -Djava.security.egd = file： /dev/。/urandom” 
CATALINA_OPTS =“ $ CATALINA_OPTS -Djava.library.path = / usr / local / apr / lib”

4.HTTP请求优化

vim apache-tomcat-8.0.53 / conf / server.xml

<连接器端口=“ 8080” 
    protocol =“ org.apache.coyote.http11.Http11AprProtocol” 
    connectionTimeout =“ 10000” 
    redirectPort =“ 8443” 
    maxThreads =“ 5000” 
    minSpareThreads =“ 20” 
    acceptCount =“ 1000” 
    enableLookups =“ false” 
    URIEncoding =“ UTF-8” 
    useBodyEncodingForURI =“ true” 
    compression =“ on” 
    compressionMinSize =“ 2048” 
    noCompressionUserAgents =“ gozilla，traviata” 
    compressableMimeType =“ text / html，text / xml，application / javascript，text / css，text / plain，image / jpeg，image / gif” 
/>

5.隐藏版本

cd apache-tomcat-8.0.53 / lib /;
解压缩catalina.jar

修改版本信息

该组织/阿帕奇/卡塔利娜/ UTIL / ServerInfo.properties

server.info = lstest server.number = 2017 server.built = 2017

修改后的信息压缩回jar包

jar uvf catalina.jar组织/apache/catalina/util/ServerInfo.properties

重启tomcat
