centos7安装mysql+tomcat+jdk并设置开机自启（已测试）

vim /etc/profile

http_proxy=192.168.228.120:8888 
https_proxy =192.168.228.120:8888 
ftp_proxy =192.168.228.120:8888 
export http_proxy https_proxy ftp_proxy 

service network restart

 

2.下载阿里yum源，让如/etc/yum.repos.d/文件夹中

wget -O /etc/yum.repos.d/CentOS-Base.repo http: //  mirrors.aliyun.com/repo/Centos-7.repo 

3.安装jdk8

 #解压
tar  -xzvf jdk-8u172-linux-x64.gz

vim /etc/profile

#在/etc/ profile文件中配置环境变量
JAVA_HOME =/home/tools/jdk1.8 .0_172
PATH =$JAVA_HOME/ bin:$PATH
CLASSPATH =.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/ tools.jar
export JAVA_HOME
export PATH
export CLASSPATH 

 #刷新文件
source  /etc/profile

4.安装mysql5.7

 #下载官方包
wget  -i -c http: //  dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm 
 
#加载入yum中
yum  -y install mysql57-community-release-el7-10 .noarch.rpm

#安装mysql
yum install java -1.8.0- openjdk.x86_64

#启动mysql
systemctl start mysqld.service

#查看mysql密码
grep  "password" /var/log/ mysqld.log

#修改mysql密码
##进入mysql,设置密码策略为low
mysql  -uroot - pxxxx
set global validate_password_policy = LOW;
ALTER USER  ‘root‘@‘localhost‘ IDENTIFIED BY ‘zxyt2018‘ ;

#修改mysql访问权限
use mysql
update user set host  = ‘%‘ where user = ‘root‘ ;
flush privileges;

#防火墙管理
systemctl stop firewalld
systemctl disable firewalld.service 

  5 .tomcat安装(将tomcat8通过ftp上传至服务器)

 #解压
tar  -xzvf apache-tomcat-8.5.9 .tar.gz

#将tomcat加入环境变量
vim apache -tomcat-8.5.39/bin/ catalina.sh

#加入下面命令大概在  143 行 :set number 143 
CATALINA_PID ="$CATALINA_BASE/tomcat.pid" 

# /usr/lib/systemd/ system下创建文件tomcat.service
systemctl enable tomcat #设置开机自启
systemctl start /stop/ restart tomcat 开始/停止/重启 tomcat

6.资源文件

  tomcat.service
  

 [Unit]
Description = tomcat
After =syslog.target network.target remote-fs.target nss- lookup.target
 
[Service]
Type = forking
 
Environment ="JAVA_HOME=/home/tools/jdk1.8.0_172" 
 
PIDFile =/home/tools/apache-tomcat-8.5.9/ tomcat.pid
ExecStart =/home/tools/apache-tomcat-8.5.9/bin/ startup.sh
ExecStop =/home/tools/apache-tomcat-8.5.9/bin/ shutdown.sh
ExecReload =/bin/kill - s HUP $MAINPID
PrivateTmp = true  
 
[Install]
WantedBy =multi-user.target

tomcat、jdk、mysql这里上传不了那么大，就去官网找下资源。……
