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

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.
[root@localhost tomcat]# systemctl status haveged
● haveged.service - Entropy Daemon based on the HAVEGE algorithm

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
