安装JAVA

1、卸载原有openJDK

2、下载jdk rpm安装包

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

image.png

3、上传到服务端

4、更改文件权限并安装

chmod 777 jdk-8u181-linux-x64.rpm
rpm -ivh jdk-8u181-linux-x64.rpm

image.png

5、添加环境变量

用编辑器打开文件

vi /etc/profile

添加变量

export JAVA_HOME=/usr/java/jdk1.8.0_181-amd64
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

6、更新源文件

source /etc/profile

7、检查java环境

安装haveged

1、检查是否需要安装haveged(<1000)

cat /proc/sys/kernel/random/entropy_avail

image.png

2、安装haveged

yum install epel-release -y
yum install haveged -y

image.png

3、设置启动

[root@localhost tomcat]# systemctl start haveged
[root@localhost tomcat]# systemctl enable haveged 
Created symlink from /etc/systemd/system/multi-user.target.wants/haveged.service to /usr/lib/systemd/system/haveged.service.

安装TOMCAT

1、下载安装包

https://tomcat.apache.org/download-80.cgi

2、解压到安装路径

mkdir /opt/tomcat
sudo tar -zxvf apache-tomcat-8.0.50.tar.gz -C /opt/tomcat --strip-components=1

3、试运行tomcat

cd /opt/tomcat/bin
./startup.sh

image.png

关闭Tomcat

./shutdown.sh

Tomcat创建systemd unit 文件

sudo vi /etc/systemd/system/tomcat.service

写入

[Unit]
Description=Apache Tomcat Web Application Container
After=syslog.target network.target
[Service]
Type=forking
Environment=JAVA_HOME=试运行时出现的路径
Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/bin/kill -15 $MAINPID
User=tomcat
Group=tomcat
[Install]
WantedBy=multi-user.target

设置自动启动

sudo systemctl start tomcat.service
sudo systemctl enable tomcat.service

4、开启防火墙

sudo firewall-cmd --zone=public --permanent --add-port=8080/tcp
sudo firewall-cmd --reload

image.png

5、访问http://IP:8080页面

image.png

6、设置Tomcat管理员账号密码

vi /opt/tomcat/conf/tomcat-users.xml

添加

<role rolename="manager"/>
<role rolename="manager-gui"/>
<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user username="root" password="hello12345" roles="admin-gui,admin,manager-gui,manager,manager-script,manager-jmx,manager-status"/>

7、取消IP限制

vi /opt/tomcat/webapps/manager/META-INF/context.xml

将【<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127.\d+.\d+.\d+|::1|0:0:0:0:0:0:0:1" />】注释

启动MySQL

service mysqld start

重新设置mysql root账号

 [root@localhost ~]# sudo grep 'temporary password' /var/log/mysqld.log
2019-01-10T10:02:21.971876Z 1 [Note] A temporary password is generated for root@localhost: fQv3YsS-RjZA

登录mysql root账号

 [root@localhost ~]# mysql -uroot -pfQv3YsS-RjZA

mysql默认账号密码强度有一定要求，如果是测试环境或本地环境想设置简单密码，则需要先调整密码强度设置

调整密码长度要求

mysql> set global validate_password_length=0;

调整密码强度检查等级，0/LOW、1/MEDIUM、2/STRONG

mysql> set global validate_password_policy=0;

设置密码为123456

mysql> set password for 'root'@'localhost' = password('123456');

设置root允许远程登录

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

刷新缓存并退出

mysql> flush privileges;
mysql> exit
