第一步安装 软件
1.1 依赖包
# yum -y install gcc
# yum install expat-devel
# sudo yum install zlib-devel
到http://apr.apache.org/download.cgi#apr1这个地址下载所需要的包
apr-1.6.5.tar.gz
apr-iconv-1.2.2.tar.gz
apr-util-1.6.1.tar.gz
1.2安装APR
tar zxvf apr-1.6.5.tar.gz
cd apr-1.6.5
./configure --prefix=/usr/local/apr
make
make install
cd ..写入到环境变量中
vi /etc/profile
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib
source /etc/profile
如果这个不写，第一次启动tomcat 没有问题，第二次就挂了，不知道什么鬼1.3安装apr-iconv
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 ..
1.4安装 apr-util
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
cd ..1.5 安装openssl-1.0.2
[root@localhost openssl-1.0.2f]# wget http://www.openssl.org/source/openssl-1.0.2f.tar.gz
[root@localhost openssl-1.0.2f]# tar -xzf openssl-1.0.2f.tar.gz
[root@localhost openssl-1.0.2f]# cd openssl-1.0.2f
[root@localhost openssl-1.0.2f]# mkdir /usr/local/openssl
[root@localhost openssl-1.0.2f]# ./config -fPIC --prefix=/usr/local/openssl enable-shared
[root@localhost openssl-1.0.2f]# make clean
[root@localhost openssl-1.0.2f]# make
[root@localhost openssl-1.0.2f]# make install
查看路径
[root@localhost openssl-1.0.2f]# which openssl
/usr/local/openssl/bin/openssl
[root@localhost openssl-1.0.2f]# mv /usr/bin/openssl /usr/bin/openssl.bak1
[root@localhost openssl-1.0.2f]# ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
[root@localhost openssl-1.0.2f]# cd /usr/local/openssl
---------------------
查看版本
[root@localhost openssl-1.0.2f]# openssl version
/usr/local/openssl/bin/openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or director
找不到动态库libssl.so.1.1，小问题，执行如下命令：
[root@localhost openssl-1.0.2f]# vim /etc/ld.so.conf
在最后追加一行：
/usr/local/openssl/lib
然后执行：
[root@localhost openssl-1.0.2f]# ldconfig /etc/ld.so.conf
[root@localhost openssl-1.0.2f]# openssl version
OpenSSL 1.1.0f 25 May 2017
4.检测安装是否成功
openssl version -a第二步 tomcat优化
2.1进入文件夹tomcat/bin. 打开catalina.sh文件，
找到下面的注释
# OS specific support. $var _must_ be set to either true or false.
export JAVA_OPTS="-server -Xms512M -Xmx1400M -Xss512k -XX:+AggressiveOpts -XX:+UseBiasedLocking -XX:+DisableExplicit
2.2tomcat 配置文件
# mv /usr/local/tomcat/conf/server.xml /usr/local/tomcat/conf/server.xml.bak
# vi /usr/local/tomcat/conf/server.xml
<Server port="8005" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.startup.VersionLoggerListener" />

</Host>
</Engine>
</Service>
</Server>2.3tomcat 安装native
cd /usr/local/tomcat/bin/
tar xzfv 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_191-amd64 --with-ssl=/usr/local/openssl
【备用命令./configure --with-apr=/usr/bin/apr-1-config】
make
make install安装成功后提示
2.4 tomcat整合 apr
vim /etc/profile
#在文件中加入下面这句话
export CATALINA_OPTS=-Djava.library.path=/usr/local/apr/lib
#使配置生效
source /etc/profile2.5 修改tomcat 配置文件
vim tomcat/conf/server.xml
#将配置中的
Connector port="8080" protocol="HTTP/1.1"
改成
Connector port="8080" protocol="org.apache.coyote.http11.Http11AprProtocol"
将配置中的
Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
改成
Connector port="8009" protocol="org.apache.coyote.ajp.AjpAprProtocol" redirectPort="8443"
重启tomcat，启动日志出现以下内容证明此时以APR模式启动
3，安装nginx 以及性能优化
3.1 SSL功能需要openssl库，下载地址：http://www.openssl.org/
3.2 gzip模块需要zlib库，下载地址：http://www.zlib.net/
3.3 rewrite模块需要pcre库，下载地址：http://www.pcre.org/
