1. 下载安装编译工具
|
1 |
yum groupinstall 'Development Tools' |
2. 安装依赖包
|
1 |
yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses curl gdbm-devel db4-devel libXpm-devel libX11-devel gd-devel gmp-devel expat-devel xmlrpc-c xmlrpc-c-devel libicu-devel libmcrypt-devel libmemcached-devel |
3. 下载并解压PHP7.4
|
1 2 3 |
wget http://php.net/distributions/php-7.4.0.tar.gz tar -zxvf php-7.4.0.tar.gz cd php-7.4.0 |
4. 编译安装（./configure –help 查看编译参数）
如果未使用本博客安装 Nginx 教程或未创建用户则需要，新增用户组，用户，用于编译使用
|
1 |
useradd -s /sbin/nologin -M nginx |
开始编译
|
1 2 |
./configure --prefix=/usr/local/php --with-config-file-path=/etc --with-fpm-user=nginx --with-fpm-group=nginx --with-curl --with-freetype-dir --enable-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip --enable-fpm make && make install |
5. 环境配置
执行完安装命令后php7.4就已经安装在到了/usr/local/php目录下了
|
1 |
/usr/local/php/bin/php -v |
添加环境变量
|
1 |
vim /etc/profile |
在最后一行后面添加
|
1 2 |
PATH=$PATH:/usr/local/php/bin export PATH |
更新环境变量
|
1 |
source /etc/profile |
查看版本
|
1 |
php -v |
6. 配置php-fpm
|
1 2 3 4 5 6 |
cp php.ini-production /etc/php.ini cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm cp sapi/fpm/php-fpm.service /usr/lib/systemd/php-fpm.service chmod +x /etc/init.d/php-fpm |
启动php-fpm
|
1 2 3 4 |
/etc/init.d/php-fpm start service php-fpm start 或者 systemctl start php-fpm.service |
报错处理
使用systemctl start php-fpm.service启动后在status中出现以下错误
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
[root@grafana systemd]# systemctl status php-fpm.service ● php-fpm.service - The PHP FastCGI Process Manager Loaded: loaded (/usr/lib/systemd/system/php-fpm.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since Wed 2021-12-29 03:59:03 UTC; 20s ago Process: 19189 ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf (code=exited, status=78) Main PID: 19189 (code=exited, status=78) Dec 29 03:59:03 grafana systemd[1]: Started The PHP FastCGI Process Manager.

此时，selinux是关闭状态，普通用户对这个文件也可写，问题就迷离了。
解决方法1：
|
1 2 3 4 5 |
vim /usr/lib/systemd/system/php-fpm.service ProtectSystem=true 或full 修改为 ProtectSystem=false |
当这个值为true的时候，php-fpm进程将以只读的方式挂载 /usr 目录，这就是问题所在。具体可参考：https://www.freedesktop.org/software/systemd/man/systemd.exec.html#ProtectSystem=
解决方法2：
但是为了安全我不是很推荐修改为false，建议更换php-fpm log所在目录至/var/log/php-fpm.log
|
1 2 3 |
vim /usr/local/php/etc/php-fpm.conf 在文件内添加以下命令 error_log = /var/log/php-fpm.log |
