export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
source /etc/profile
java -version
sudo rpm -ivh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
sudo yum repolist all | grep mysql | grep enabled
如果展示像下面,则表示成功添加仓库:
mysql-connectors-community/x86_64 MySQL Connectors Community enabled: 51
mysql-tools-community/x86_64 MySQL Tools Community enabled: 63
mysql57-community/x86_64 MySQL 5.7 Community Server enabled: 267
sudo yum -y install mysql-community-server
1.启动
sudo systemctl start mysqld
2.设置系统启动时自动启动
sudo systemctl enable mysqld
3.查看启动状态
sudo systemctl status mysqld

[mysqld]
collation-server = utf8_unicode_ci
init-connect=‘SET NAMES utf8‘
character-set-server = utf8
3.重启Mysql即可
sudo systemctl restart mysqld
1. 创建文件夹
mkdir nodejs
2. 进入文件夹
cd nodejs
3.下载源码(官网查看最新版本链接)
wget http://nodejs.org/dist/v0.10.30/node-v0.10.30.tar.gz
4.解压源码
tar xzvf node-v* && cd node-v*
注意解压缩的文件名称与现存的关系,不要弄混了
5.安装必要的编译软件
sudo yum install gcc gcc-c++
6.编译
./configure
make
