Centos7下jdk、mysql、iptables、nginx、redis安装简介

一.JDK

# jdk
yum search java | grep -i --color JDK
yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel
cd /usr/lib/jvm/
cd java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64/
# 配置环境变量
vim /etc/profile
# 在文件最后面添加如下三行内容(具体路径根据自己的实际情况确定) export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin
# 使配置文件即时生效 source /etc/profile
# 检查jdk是否安装按成 java -version

二.MySQL

# mysql rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm yum repolist enabled | grep "mysql.*" yum -y install mysql-community-server

# 常用操作命令 systemctl enable mysqld systemctl start mysqld systemctl status mysqld.service

三.iptables

# iptables
# 停止firewalld systemctl stop firewalld # 屏蔽firewalld systemctl mask firewalld
yum install iptables-services
# 启用iptables systemctl enable iptables
systemctl start iptables service iptables save
# 配置iptables规则 vim /etc/sysconfig/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT # 重启iptables systemctl restart iptables

四.Nginx

# nginx rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm yum info nginx yum install nginx

五.Redis

# redis yum install epel-release && yum install redis cp /etc/redis.conf /etc/redis.conf.back

# 配置redis密码(强烈建议) vim /etc/redis.conf

# 在配置文件中找到requirepass,将前面的#号注释放开,后面填上自己的redis密码,保存文件,重启redis即可 requirepass password service redis start
