Nginx安装部署【简单】

简介

Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器，同时也提供了IMAP/POP3/SMTP服务。
Nginx可以托管用户编写的WEB应用程序成为可访问的网页服务，同时也可以作为流量代理服务器，控制流量的中转。
Nginx在WEB开发领域，基本上也是必备组件之一。

安装

Nginx需要配置额外的yum仓库，才可以使用yum安装

安装Nginx的操作需要root身份

安装yum依赖程序
shell 复制代码
```
# root执行
yum install -y yum-utils
```

手动添加，nginx的yum仓库

yum程序使用的仓库配置文件，存放在：/etc/yum.repo.d内。

shell 复制代码

# 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，手动添加nginx的yum仓库

通过yum安装最新稳定版的nginx
shell 复制代码
```
# root执行
yum install -y nginx
```

启动

bash 复制代码

# 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

配置防火墙放行

nginx默认绑定80端口，需要关闭防火墙或放行80端口

shell 复制代码

# 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

启动后,浏览器输入Linux服务器的IP地址或主机名即可访问
- http://192.168.xxx.xxx
ps：80端口是访问网站的默认端口，所以后面无需跟随端口号

至此，Nginx安装配置完成。

RabbitMQ安装部署【简单】

简介

RabbitMQ一款知名的开源消息队列系统，为企业提供消息的发布、订阅、点对点传输等消息服务。
RabbitMQ在企业开发中十分常见，课程为大家演示快速搭建RabbitMQ环境。

安装

rabbitmq在yum仓库中的版本比较老，所以需要手动构建yum仓库

准备yum仓库

shell 复制代码

# root执行
# 1. 准备gpgkey密钥
rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
rpm --import https://packagecloud.io/rabbitmq/erlang/gpgkey
rpm --import https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey

# 2. 准备仓库文件
vim /etc/yum.repos.d/rabbitmq.repo
# 填入如下内容
##
## Zero dependency Erlang
##

[rabbitmq_erlang]
name=rabbitmq_erlang
baseurl=https://packagecloud.io/rabbitmq/erlang/el/7/$basearch
repo_gpgcheck=1
gpgcheck=1
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

[rabbitmq_erlang-source]
name=rabbitmq_erlang-source
baseurl=https://packagecloud.io/rabbitmq/erlang/el/7/SRPMS
repo_gpgcheck=1
gpgcheck=0
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

##
## RabbitMQ server
##

[rabbitmq_server]
name=rabbitmq_server
baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/7/$basearch
repo_gpgcheck=1
gpgcheck=0
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

[rabbitmq_server-source]
name=rabbitmq_server-source
baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/7/SRPMS
repo_gpgcheck=1
gpgcheck=0
enabled=1
gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

安装RabbitMQ

shell 复制代码

# root执行
yum install erlang rabbitmq-server -y

启动

shell 复制代码

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

放行防火墙，RabbitMQ使用5672、15672、25672 3个端口

shell 复制代码

# 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

bash 复制代码

# 启动有报错的信息但是，查看状态
[root@yuan ~]# systemctl start rabbitmq-server
Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

启动RabbitMQ的WEB管理控制台

shell 复制代码

rabbitmq-plugins enable rabbitmq_management

bash 复制代码

# 停止RabbitMQ管理插件
rabbitmq-plugins disable rabbitmq_management

添加admin用户，并赋予权限

shell 复制代码

rabbitmqctl add_user admin 'yuan66^'
rabbitmqctl set_permissions -p "/" "admin" ".*" ".*" ".*"
rabbitmqctl set_user_tags admin administrator

浏览器打开管理控制台
