创建常用目录
sudo mkdir /data sudo chown -R oper data cd /data mkdir apps
2. 安装数据库mysql5.7
# Step0:安装所需的yum命令 sudo yum -y install yum-utils # Step1: 检测系统是否自带安装mysql sudo yum list installed | grep mysql # Step2: 删除系统自带的mysql及其依赖命令: sudo yum -y remove mysql-libs.x86_64 # Step3: 给CentOS添加rpm源,并且选择较新的源命令: wget dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm sudo yum localinstall mysql-community-release-el7-5.noarch.rpm sudo yum repolist all | grep mysql sudo yum-config-manager --disable mysql55-community sudo yum-config-manager --disable mysql56-community sudo yum-config-manager --enable mysql57-community-dmr sudo yum repolist enabled | grep mysql # Step4:安装mysql 服务器命令: sudo yum install mysql-community-server # Step5: 启动mysql命令: service mysqld start # Step6: 查看mysql是否自启动,并且设置开启自启动命令: chkconfig --list | grep mysqld chkconfig mysqld on # Step7: mysql安全设置命令: # 获取root临时密码 grep 'temporary password' /var/log/mysqld.log # 修改root密码 mysql_secure_installation # 根据提示修改root密码 ... # 登录命令(根据提示输入root密码登录): mysql -u root -p # 创建数据库: create database clouds_business; 创建用户: create user yunch identified by 'Yunch!2#$5^'; # 授权数据库给用户 grant all on clouds_business.* to yunch;
3. 安装jdk1.8
# 1、在Oracle官方网址下载linux-64位的jdk的RPM包,如:jdk-8u121-linux-x64.rpm # 2、使用SFTP工具将jar包上传至 /data/apps目录下 # 3、执行上传的rpm文件,如:rpm -ivh jdk-8u***-linux-x64.rpm # 4、配置环境变量(下面代码中版本根据实际情况调整) vi /etc/profile JAVA_HOME=/usr/java/jdk1.8.0_191-amd64 JRE_HOME=/usr/java/jdk1.8.0_191-amd64/jre PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib export JAVA_HOME JRE_HOME PATH CLASSPATH # 退出vi,使环境变量生效 source /etc/profile
4. 安装zookeeper
# 下载zookeeper安装包(建议3.4及以下版本) wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz # 解压 tar -xvf zookeeper-3.4.14.tar.gz rm -f *.gz cd zookeeper-3.4.14 cd conf # 将sample配置文件重命名成正式文件 mv zoo_sample.cfg zoo.cfg # 启动zookeeper ../bin/zkServer.sh start # 执行lsof命令观察 lsof -i 2181
5. 安装redis
wget http://download.redis.io/redis-stable.tar.gz tar -xvf ... mv redis-stable redis cd redis vi redis.conf # 修改密码和端口号 sudo make && sudo make install # 运行redis nohup redis-server redis.conf & # 日志在 nohup.out里面
6. 安装nginx
sudo yum -y install nginx # 修改权限 sudo chown -R oper /etc/nginx # 修改/etc/nginx/nginx.conf配置 #在 conf.d里面增加.conf文件 # 重启命令 sudo nginx -s reload
