nginx的三种安装方式

nginx三种安装方式

• 1.源码安装 (1.版本随意 2.安装复杂 3.升级繁琐 4.规范 5. 便于管理)
• 2.yum安装 (1.版本较低 2.安装简单 3.配置不易读)
• 3.官方仓库安装 (1.版本较新 2.安装简单 3.配置易读)

源码安装

• 到官方网站去下载安装包

# nginx官网，下载源码包
cd /root/
wget http://nginx.org/download/nginx-1.20.2.tar.gz

# 解压
tar xf nginx-1.20.2.tar.gz

# 生成:安装的位置在/opt/nginx-1.20.2
cd /root/nginx-1.20.2/
./configure --prefix=/opt/nginx-1.20.2 --with-http_ssl_module --with-http_stub_status_module

# 报错1 缺少c语言
./configure: error: C compiler cc is not
found
## 解决方法
yum install -y gcc gcc-c++ glibc
# 报错2 缺少pcre依赖
./configure: error: the HTTP rewritemodule requires the PCRE library.You can either disable the module byusing --without-http_rewrite_moduleoption, or install the PCRE library intothe system, or build the PCRE librarystatically from the source with nginx byusing --with-pcre=<path> option.
# 解决方法
yum install -y pcre-devel
# 报错3 缺少openssl依赖
/configure: error: SSL modules requirethe OpenSSL library.You can either do not enable themodules, or install the OpenSSL libraryinto the system, or build the OpenSSLlibrary statically from the sourcewith nginx by using --with-openssl=<path> option.
## 解决方法
yum install -y openssl-devel

# 总解决方法
yum install -y openssl-devel pcre-devel gcc gcc-c++ glibc

# 编译（为了让系统能识别你的代码，并且吧刚才指定的功能和路径编辑到源码中）
make

# 安装
make install


# 做软连接
ln -s /opt/nginx-1.20.2/ /opt/nginx

# 增加环境变量，可通过文件名称执行
vim /etc/profile.d/nginx.sh
export PATH="$PATH:/opt/nginx/sbin"

# 生效环境变量
source /etc/profile

# 查看是否添加成功
[root@web01 ~]# echo $PATH 
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/opt/nginx/sbin

# 关闭防火墙
systemctl stop firewalld
# 关闭selinux
vim /etc/sysconfig/selinux
selinux=disable

## 启动nginx
[root@web01 ~]# nginx

## 停止nginx
- 杀进程   
- nginx -s stop

官方源安装

# 添加nginx源
vim /etc/yum.repos.d/nginx.repo

[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

# 安装nginx
yum install -y nginx

1.Nginx启动

[root@zls ~]# /usr/sbin/nginx
[root@zls ~]# systemctl start nginx

2.Nginx停止

[root@zls ~]# /usr/sbin/nginx -s stop
[root@zls ~]# systemctl stop nginx

3.Nginx重启

[root@zls ~]# systemctl restart nginx

4.Nginx重载

[root@zls ~]# /usr/sbin/nginx -s reload
[root@zls ~]# systemctl reload nginx

yum安装nginx

# 安装方法
yum instll -y nginx

## 安装的是通过本地源安装
[root@web01 ~]# ll /etc/yum.repos.d/
-rw-r--r--. 1 root root 2523 Apr 11 17:05 CentOS-Base.repo
-rw-r--r--. 1 root root  664 Apr 11 17:05 epel.repo

换国内源

阿里源

• 下载国外源可能会丢包

# 先打包本地源
gzip /etc/yum.repos.d/*

# 下载，aliyun内有详细且最新的安装包和教程
curl -o https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.4b001b11zvIY21
wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo
