源码包安装
三种：rpm、yum、源码包安装
1、源码安装nginx
- 下载源码包
```bash
wget http://nginx.org/download/nginx-1.18.0.tar.gz
tar -xf nginx-1.18.0.tar.gz -C /opt
cd /opt/nginx-1.18.0
# 就可以看到nginx源代码
# 第二种方式：https://repo.huaweicloud.com/epel/7/x86_64/Packages/n/
wget https://repo.huaweicloud.com/epel/7/x86_64/Packages/n/nginx-1.16.1-3.el7.x86_64.rpm
``
- 直接编译
```bash
# 编译前，系统检测
[root@www nginx-1.18.0]# ./configure
# 如果出现对应的错误，则执行下面命令
[root@www nginx-1.18.0]# yum install pcre pcre-devel -y
[root@www nginx-1.18.0]# yum install zlib zlib-devel -y
# 开始编译
make
-j ： 使用多核编译
> 这里是引用
# 安装
make install PROFIX=/usr/local
# 测试
[root@www ~]# /usr/local/nginx/sbin/nginx
# 环境变量
## 添加环境变量
/etc/profile # 所用用户的环境变量
/root/.bash_profile # 当前用户的环境变量
NGINX_HOME=/usr/local/nginx/sbin
PATH=$PATH:$NGINX_HOME
export PATH
/usr/local/sbin
/usr/local/bin
/usr/sbin
/usr/bin
/root/.local/bin
/root/bin
/root/.local/bin
/root/bin
/usr/local/nginx/sbin
源码包编译 PHP
第一步 ：下载安装PHP
wget -O /opt/ php.tar.gz https://www.php.net/distributions/php-7.4.16.tar.gz
或者
cd/opt
wget php.tar.gz https://www.php.net/distributions/php-7.4.16.tar.gz
第二步 解压
tar xvf php.tar.gz
第三步 直接编译
1. #编译测试
. - 在cd /opt/php-7.4.16/ 目录下测试
输入 ./configure
2.# 如果出现对应的错误，则执行下面命令
#报错
#解决
yum install libxml2 ibxml2-devel
**# libxml2安装包有的话无需添加**
#报错
configure: error: Package requirements (sqlite3 > 3.7.4) were not met:
No package 'sqlite3' found
#解决
yum install sqlite sqlite-devel
**# sqlite安装包有的话无需添加**
# 开始编译 make -j ： 使用多核编译
> 这里是引用
# 安装 make install PROFIX=/usr/local
3. #执行 ./configure 命令时，可能会因为 Linux 尚未安装某些库而报错，
安装即可解决。
配置成功后会看到授权信息
