Nginx在CentOS上的安装部署、RabbitMQ在CentOS上安装部署

# root执行
yum install -y yum-utils

1.2.2  手动添加，nginx的yum仓库

# root执行
# 创建文件使用vim编辑
vim /etc/yum.repos.d/nginx.repo
# 填入如下内容并保存退出
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
 
[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

通过如上操作，我们手动添加了 nginx 的 yum 仓库

# root执行
yum install -y nginx

1.2.4  启动

# nginx自动注册了systemctl系统服务
systemctl start nginx # 启动
systemctl stop nginx # 停止
systemctl status nginx # 运行状态
systemctl enable nginx # 开机自启
systemctl disable nginx # 关闭开机自启

1.2.5  配置防火墙放行

# 方式1（推荐），关闭防火墙
systemctl stop firewalld # 关闭
systemctl disable firewalld # 关闭开机自启
 
# 方式2，放行80端口
firewall-cmd --add-port=80/tcp --permanent # 放行tcp规则下的80端口，永久生效
firewall-cmd --reload # 重新加载防火墙规则

1.2.6  启动后浏览器输入Linux服务器的IP地址或主机名即可访问

注意：

80端口是访问网站的默认端口，所以后面无需跟随端口号

显示的指定端口也是可以的比如：

http: / 192.168.88.130:80

http: / centos:80

2.  RabbitMQ在CentOS上安装部署

1 # root执行
2 # 1. 准备gpgkey密钥
3 rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
4 rpm - import
https://packagecloud.io/rabbitmq/erlang/gpgkey
5 rpm - import
https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
6
7 # 2. 准备仓库文件
8 vim /etc/yum.repos.d/rabbitmq.repo
9 # 填入如下内容
10 #
11 # Zero dependency Erlang
12 #
13
14 [rabbitmq_erlang]

由于格式的问题，可能看着有些混乱，我在下面截了图：

# root执行
yum install erlang rabbitmq-server -y

Installed:
  erlang.x86_64 0:23.3.4.11-1.el7
rabbitmq-server.noarch 0:3.10.0-1.el7

2.2.3  启动

# root执行
# 使用systemctl管控，服务名：rabbitmq-server
systemctl enable rabbitmq-server # 开机自启
systemctl disable rabbitmq-server # 关闭开机自启
systemctl start rabbitmq-server # 启动
systemctl stop rabbitmq-server # 关闭
systemctl status rabbitmq-server # 查看状态

2.2.4  放行防火墙，RabbitMQ使用5672、15672、25672 3个端口

# 方式1（推荐），关闭防火墙
systemctl stop firewalld # 关闭
systemctl disable firewalld # 关闭开机自启
 
# 方式2，放行5672 25672端口
firewall-cmd --add-port=5672/tcp --permanent
# 放行tcp规则下的5672端口，永久生效
firewall-cmd --add-port=15672/tcp --permanent
# 放行tcp规则下的15672端口，永久生效
firewall-cmd --add-port=25672/tcp --permanent
# 放行tcp规则下的25672端口，永久生效
firewall-cmd --reload
# 重新加载防火墙规则

2.2.5  启动RabbitMQ的WEB管理控制台

rabbitmq-plugins enable rabbitmq_management

2.2.6  添加admin用户，并赋予权限

rabbitmqctl add_user admin 'Itheima66^'
rabbitmqctl set_permissions -p "/" "admin" ".*" ".*" ".*"
rabbitmqctl set_user_tags admin administrator

2.2.7  浏览器打开管理控制台
