PHP8编译安装

## CentOS8编译安装PHP8

PHP，全称Hypertext Preprocessor（超文本预处理器），是一种通用开源脚本语言。它特别适合于web开发，并能嵌入HTML中。现在主要用于PHP网站中实现动态网站功能，常规我们使用nginx、apache部署的是html静态网页，可以通过.php编写动态页面实现。

### 一、下载
```shell
# 创建文件夹用来安装php
mkdir /www/php80

# 官网下载然后上传到服务器或者wget下载到对应文件夹
wget https://www.php.net/distributions/php-8.1.7.tar.gz

# 解压文件
tar -zxvf php-8.1.7.tar.gz

# 修改文件夹用户和组,防止没有权限执行
chown -R root php-8.1.7
chgrp -R root php-8.1.7
cd php-8.1.7
```
### 二、安装配置
```shell
# 和nginx编译安装类似，使用.configure进行配置
# --prefix:php.ini文件路径位置
# --with-config-file-path ： 配置文件
./configure --prefix=/www/php8 --with-config-file-path=/www/php8/etc --with-curl --with-freetype --enable-gd --with-jpeg  --with-gettext --with-kerberos --with-libdir=lib64 --with-libxml --with-mysqli --with-openssl --with-pdo-mysql  --with-pdo-sqlite --with-pear --enable-sockets --with-mhash --with-ldap-sasl --with-xsl --with-zlib --with-zip -with-bz2 --with-iconv  --enable-fpm --enable-pdo  --enable-bcmath  --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl  --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-xml --enable-sysvsem --enable-cli --enable-opcache --enable-intl --enable-calendar --enable-static --enable-mysqlnd
```

Thank you for using PHP.
```

安装：
```shell
make && make install

完成：
Don't forget to run 'make test'.

```

### 三、文件设置
1.php-ini，将源码目录下的php.ini-production复制到自己的目录下
```shell
cp php.ini-production /www/php8/etc/php.ini
```
2.生成www配置文件,将目录下的模板文件重命名
```shell
cd /www/php8/etc/php-fpm.d/
cp www.conf.default www.conf
```
3.生成php-fpm配置文件
```shell
cd /www/php8/etc/
cp php-fpm.conf.default php-fpm.conf
```
4.生成php-fpm可执行文件
```shell
# 创建存放配置文件的目录
mkdir php-fpm

# 从源码中复制一份fpm可执行脚本
cp /www/php-8.1.7/sapi/fpm/init.d.php-fpm /www/php8/etc/php-fpm/php-fpm

# 修改可执行文件的权限
chmod 740 php-fpm
```

### 四、进程启用管理
```shell
# 使用可执行文件进行启动
cd /www/php8/etc/php-fpm/
./php-fpm start
# 正常启动：
Starting php-fpm  done
# ps查看进程是否启动
ps -aux | grep php-fpm
# 查看php-fpm进程占用的端口，正常应该是9000
netstat -nltp
# 查看php版本
cd /www/php8/bin/
./php -v
```
使用systemctl管理服务
```shell
# 修改/php/etc/php-fpm.conf
[global]
; Pid file
; Note: the default prefix is /www/php8/var
; Default Value: none
; pid = run/php-fpm.pid # 将前面分号删除

vim /usr/lib/systemd/system/php-fpm.service
# 添加下面内容，目录要配置自己的对应目录
[Unit]
Description=The PHP FastCGI Process Manager
After=syslog.target network.target

[Service]
Type=forking
PIDFile=/var/run/php-fpm.pid
ExecStart=/usr/local/php/sbin/php-fpm
ExecReload=/bin/kill -USR2 $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target
# 保存文件

# 使用systemctl管理
systemctl daemon-reload # 刷新systemctl
systemctl start php-fpm # 启动进程
systemctl stop php-fpm  # 结束进程
systemctl enable php-fpm# 开机启动
```

### 五、模块功能更新
1.进入源码目录进行编译安装
```shell
# php -m输出php的功能模块,在源码包的ext里面可以看到相应的模块，这些是自带的模块
cd /www/php-8.1.7/ext/

# 查看模块
ls

# 测试exif
cd exif

# 进入文件夹，使用phpize生成configure文件进行编译安装
cd /www/php8/bin/phpize

# 编译时指定配置文件
./configure --with-php-config=/www/php8/bin/php-config

# 安装
make && make install

# 安装完成之后会出现一个目录，里面包含了exif.so文件
# 修改php.ini，在最后添加上添加模块的路径
vim /www/php8/etc/php.ini
extension=/www/php8/lib/php/extensions/no-debug-non-zts-20210902/exif.so
# 保存，重启php-fpm进程
# 通过php -m 查看模块功能已经添加
```
