1、安裝jdk
java -version //查看已安裝java版本
yum -y list java* //查看當(dāng)前yum源已有jdk版本
yum -y install java-1.8.0-openjdk* //安裝jdk1.8.0所需所有岂丘，單獨(dú)安裝具體到名稱(chēng)
rpm -qa | grep java //查看當(dāng)前安裝的jdk中所有的子內(nèi)容陵究，//若重裝則盡量卸載干凈
yum -y remove java-1.8.0-openjdk* //卸載jdk1.8.0的所有內(nèi)容
2、安裝tomcat
systemctl status tomcat //查看服務(wù)器tomcat狀態(tài)
yum -y install tomcat //yum安裝tomcat
systemctl status tomcat //查看tomcat運(yùn)行狀況奥帘，dead為死亡铜邮，未運(yùn)行狀態(tài)，running（綠色）則是運(yùn)行狀態(tài)
systemctl start tomcat //啟動(dòng)tomcat
cd /usr/share/tomcat/webapps //進(jìn)入webapps文件夾
yum install tomcat-webapps tomcat-admin-webapps //安裝默認(rèn)瀏覽器管理界面寨蹋，若不執(zhí)行訪問(wèn)ip：端口會(huì)顯示找不到網(wǎng)頁(yè)
yum remove tomcat //卸載tomcat
3松蒜、安裝mysql
rpm -qa | grep mysql //查看當(dāng)前已安裝的mysql
yum remove mysql-xxx-xxx- //卸載mysql
find / -name mysql //查找mysql的相關(guān)文件
rm -rf /var/lib/mysql //根據(jù)自身的需求刪除mysql的配置文件信息
rpm -qa | grep mariadb //查看當(dāng)前已安裝的mariadb
rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64 //將查找出來(lái)的結(jié)果進(jìn)行強(qiáng)制刪除
這里應(yīng)該還需要從官網(wǎng)wgetmysql源
yum install mysql-community-server //安裝mysql
systemctl start mysqld //啟動(dòng)mysql
cat /var/log/mysqld.log | grep password //查看mysql初始生成的隨機(jī)密碼
mysql -u root -p //進(jìn)入mysql命令行
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'yourpassword'; //給root更改密碼
mysql> use mysql;
mysql> update user set host='%' where user='root'; //遠(yuǎn)程設(shè)置
mysql> use mysql;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密碼'; //創(chuàng)建并設(shè)置加密方式
mysql> FLUSH PRIVILEGES; //刷新權(quán)限
4、安裝nginx
安裝nginx鏡像源已旧，一般是沒(méi)有這個(gè)源的
sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum search nginx //查找鏡像源
sudo yum install -y nginx //安裝nginx
sudo systemctl start nginx.service
sudo systemctl enable nginx.service //啟動(dòng)Nginx并設(shè)置開(kāi)機(jī)自動(dòng)運(yùn)行
