Linux系統(tǒng)：第十章：服務器環(huán)境搭建

將防火墻關閉并設置為開機不自動啟動：

systemctl stop firewalld.service

systemctl disable firewalld.service
Linux系統(tǒng)中JDK的安裝與配置

進入opt目錄下 ：cd /opt

在opt目錄下上傳jdk文件 ：jdk-8u152-linux-x64.tar.gz

解壓 ：tar -zxvf jdk-8u152-linux-x64.tar.gz

進入etc目錄下：cd /etc

備份：cp profile profile.bak

修改：vim profile

大寫G，進入文件末尾，輸入i進行修改模式，末尾添加以下配置：
 

    JAVA_HOME=/opt/jdk1.8.0_152
     
    PATH=$JAVA_HOME/bin:$PATH
     
    export JAVA_HOME PATH

然后保存退出：按Esc+：wq

執(zhí)行當前連接剛剛配置的腳本文件使配置文件生效：source /etc/profile     或者reboot重啟

查看jdk版本：java -version

    java version "1.8.0_152"
    Java(TM) SE Runtime Environment (build 1.8.0_152-b16)
    Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)

查看：path路徑：echo $PATH

/opt/jdk1.8.0_152/bin:/opt/jdk1.8.0_152/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

查看：JAVA_HOME路徑：echo $JAVA_HOME

/opt/jdk1.8.0_152

Tomcat安裝與配置

進入opt目錄：cd /opt

在opt目錄下上傳apache-tomcat-8.5.24.tar.gz

解壓： tar -zxvf apache-tomcat-8.5.24.tar.gz

啟動tomcat： /opt/apache-tomcat-8.5.24/bin/startup.sh

如果報錯進入logs目錄查看：cd /opt/apache-tomcat-8.5.24/logs

查看日志：less catalina.out
MySQL的安裝與配置

進入opt目錄：cd /opt

在opt目錄下上傳MySQL-server-5.5.52-1.el6.x86_64.rpm和MySQL-client-5.5.52-1.el6.x86_64.rpm

忽略依賴關系執(zhí)行刪除：rpm -e --nodeps mariadb-libs-1:5.5.56-2.el7.x86_64

安裝服務端：rpm -ivh /opt/MySQL-server-5.5.52-1.el6.x86_64.rpm

安裝客戶端：rpm -ivh /opt/MySQL-client-5.5.52-1.el6.x86_64.rpm

查看版本：mysqladmin --version

mysqladmin  Ver 8.42 Distrib 5.5.52, for Linux on x86_64

啟動MySQL服務：systemctl start mysql.service

查看服務狀態(tài)：systemctl status mysql.service

查看端口：netstat -anp|grep 3306

查看mysql運行的進程：ps -ef|grep mysql|grep -v grep

設置root用戶和密碼：mysqladmin -u root password

New password:
Confirm new password:

登錄mysql：mysql -u root -p

Enter password:

查看數(shù)據(jù)庫：show databases;

使用test數(shù)據(jù)庫：user test;

查看表：show tables;

退出：exit；

然后去windows的sqlYog連接，主機改為linux連接：192.168.134.100，用戶名：root，密碼：root

測試連接不上，linux中查看防火墻：systemctl status firewalld.service

防火墻關了，沒問題，應該是mysql授權問題

登錄mysql：mysql -u root -p

查看數(shù)據(jù)庫：show databases;

使用mysql數(shù)據(jù)庫：user mysql;

查看表：show tables;

查看用戶表：select host,user,password from user;

插入一條數(shù)據(jù)到用戶表中（密碼復制localhost的密碼）：insert into user(host,user,password) values('%','root','81F5E21E35407D884A6CD4A731AEBFB6AF209E1B');

為root授權： GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY'root' WITH GRANT OPTION;

Query OK, 0 rows affected (0.00 sec)

退出mysql：mysql exit;

重啟mysql服務：service mysql restart；或者systemctl restart mysql.service

    Shutting down MySQL... SUCCESS!
    Starting MySQL.. SUCCESS!

去windows的sqlYog連接，連接成功！
