cd node/bin/
./node -v
	v8.11.1
# 在其他目录下不能使用，
cp npm node /usr/local/bin

server {
       listen 80;
       server_name centos0.com;
       location / {
               proxy_pass http://tomcat-servers;
       }
   }

4、命令

nginx			# 启动
nginx -s reload  # 重启
nginx -s quit    # 任务完成停止
nginx -s stop    # 强制停止

安装 Docker

1	yum install -y docker-io

使用非 root 用户使用 docker

The docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can access it with sudo. For this reason, docker daemon always runs as the root user. To avoid having to use sudo when you use the docker command, create a Unix group called docker and add users to it. When the docker daemon starts, it makes the ownership of the Unix socket read/writable by the docker group.

1、创建docker 组

1	sudo groupadd docker

2、将当前用户添加到组中

1	sudo gpasswd -a ${USER} docker

3、重启 docker 服务

1	sudo systemctl restart docker

yum localinstall mysql57-community-release-el7-8.noarch.rpm
yum install mysql-community-server
