笔记整理-yum安装jdk-tomcat安装测试记录

yum安装jdk

yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel

ls /usr/lib/jvm/
java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64
ln -sv /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64 /usr/lib/jvm/jdk1.8 #不要用超连接的形式配置jdk会报错

因为软链接不是目录

[root@localhost native]# vi /etc/profile.d/jdk8.sh #配置java家环境tomcat使用

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

source /etc/profile.d/jdk8.sh

java -version
echo $JAVA_HOME
which java

下载版本会变先网页查看

wget https://mirrors.cnnic.cn/apache/tomcat/tomcat-8/v8.5.39/bin/apache-tomcat-8.5.39.tar.gz

tar xvf apache-tomcat-8.5.39.tar.gz -C /usr/local/src/ #几项根据版本号修改命令
cd /usr/local/src/apache-tomcat-8.5.39/
cd .. ; mv apache-tomcat-8.5.39/ /usr/local/tomcat ; cd

chmod +x /etc/init.d/tomcat
service tomcat restart
chkconfig --add tomcat
chkconfig tomcat on
chkconfig --list

tomcat-native 安装

yum -y install apr-devel gcc gcc-c++ openssl-devel openssl
cd /usr/local/tomcat/bin/
tar xf tomcat-native.tar.gz -C /usr/local/src/
cd /usr/local/src/tomcat-native-1.2.21-src/native/ #根据版本修改路径

[root@localhost ~]# echo $JAVA_HOME
/usr/lib/jvm/jdk1.8

./configure --with-apr=/usr/ --with-java-home=/usr/lib/jvm/jdk1.8 --with-ssl

make && make install#如果报错可以安装一下编译工具

 

提示下面其实是安装成功了配置一下库就可以了

Libraries have been installed in:
/usr/local/apr/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

需要添加库文件：
[root@xuegod63 native]# vi /etc/ld.so.conf

/usr/local/apr/lib ##添加此行

 

[root@xuegod63 native]# ldconfig
[root@xuegod63 native]# echo "ldconfig" >>/etc/rc.local

添加环境变量:
[root@localhost native]# vi /etc/profile.d/jdk8.sh
最后添加:

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

重读生效:

[root@localhost native]#source /etc/profile.d/jdk8.sh

[root@localhost native]# vi /usr/local/tomcat/conf/server.xml 
将默认的protocol="HTTP/1.1"修改为protocol="org.apache.coyote.http11.Http11AprProtocol"

 

引用apr:
[root@localhost native]# vi /usr/local/tomcat/bin/catalina.sh
253行下面添加:

JAVA_OPTS="$JAVA_OPTS -Djava.library.path=/usr/local/apr/lib"

重启服务生效:

service tomcat restart

cat /usr/local/tomcat/logs/catalina.out | grep Native

yum install mariadb mariadb-server -y
systemctl start mariadb

 

测试数据

mysql
create database tomcat;
use tomcat;
create table tt(id int,name varchar(128));
insert into tt values (1,"come on boy"),(2,"come on girl");
grant all on tomcat.* to tomcat@localhost identified by 'tomcat';
mysql> \q
[root@XueGod63 ~]# mysql -utomcat -ptomcat

虚拟主机

vi /usr/local/tomcat/conf/server.xml

<Host name="www.xuegod63.com" appBase="/var/www/html">
<Context path="" docBase="/var/www/html/web1" />
</Host>
<Host name="www.xuegod63.cn" appBase="/var/www/html">
<Context path="" docBase="/var/www/html/web2" />

#在末尾的</Engine>上面添加上面这几行

service tomcat stop ; service tomcat start 
mkdir -p /var/www/html/{web1,web2}
echo xuegod63.com > /var/www/html/web1/index.html
echo xuegod63.cn> /var/www/html/web2/index.html #执行到这里才能监听端口没有目录tomcat无法启动
