centos7 安装apr1.7

1、安装相关依赖包

# yum -y install gcc gcc-c++ libtool* autoconf automake expat-devel perl perl-devel

2、下载安装包 
cd downsofe
https://mirrors.tuna.tsinghua.edu.cn/apache//apr/
wget https://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-1.7.0.tar.gz
wget https://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-iconv-1.2.2.tar.gz
wget http://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-util-1.6.1.tar.gz

3、安装APR

# tar zxvf apr-1.7.0.tar.gz
# cd apr-1.7.0
# vim configure

如有问题可以修改该值，经测试并没有发现该问题
默认值:
RM='$RM'
修改为:
RM='$RM -f'

# ./configure --prefix=/usr/local/apr
# make && make install

4、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

5、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

6.安装OpenSSL

# tar zxvf openssl-1.1.0f.tar.gz
# cd openssl-1.1.0f
# ./config --prefix=/usr/local/openssl
# make -j 4 && make install

7.安装tomcat-native

# cd /usr/local/tomcat/bin/
# tar zxvf tomcat-native.tar.gz
# cd tomcat-native-1.2.8-src/native
# echo $JAVA_HOME
# ./configure --with-ssl=/usr/local/openssl --with-apr=/usr/local/apr --with-java-home=/usr/local/java/jdk1.8.0_271
# make && make install
注意:如果以上 configure 失败，可以执行 make distclean 清除

8、配置相关的全局变量：

# vi /etc/profile

加入：export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib

# source /etc/profile

9.接下来需要修改tomcat配置文件中的APR运行模式，并测试是否安装成功。

# vim /usr/local/tomcat/conf/server.xml
默认值：


修改为：


默认值：


修改为：


10.现在重启tomcat服务,并查看启动日志

# systemctl restart tomcat
# cat /usr/local/tomcat/logs/catalina.out
...
INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: [/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib]
INFO [main] org.apache.coyote.AbstractProtocol.init Initializing ProtocolHandler ["http-nio-8080"]
INFO [main] org.apache.tomcat.util.net.NioSelectorPool.getSharedSelector Using a shared selector for servlet write/read
INFO [main] org.apache.coyote.AbstractProtocol.init Initializing ProtocolHandler ["ajp-nio-8009"]
INFO [main] org.apache.tomcat.util.net.NioSelectorPool.getSharedSelector Using a shared selector for servlet write/read
...
注意:如果遇到上面的提示找不到基于APR的Apache Tomcat Native库，因此无法使用APR模式启动。

解决方案：

# cp -R /usr/local/apr/lib/* /usr/lib64
# cp -R /usr/local/apr/lib/* /usr/lib
再次重启tomcat，并查看启动日志

# cat /usr/local/tomcat/logs/catalina.out
...
INFO [main] org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler ["http-apr-8080"]
INFO [main] org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler ["http-apr-8009"]
...
apr协议模式启动成功。
