安装编译php需要的依赖包:

添加www用户:
创建群组:groupadd www
创建一个用户,不允许登陆和不创主目录:useradd -s /sbin/nologin -g www -M www
编译参数:

执行编译:
make && make install
php-ini:
源码包里面有配置文件:
php.ini-development 测试开发环境
php.ini-production 生产环境
复制一份到指定的目录下(根据自己的情况选用,自己可以对比下这两个文件的差异):
cp php.ini-production /usr/local/php/etc/php.ini
php-fpm复制一份新的php-fpm配置文件:
cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
配置错误日志:error_log = /usr/local/php/var/php-fpm.log
配置pid文件:pid = /usr/local/php/var/run/php-fpm.pid
保存退出
cd /usr/local/php/etc/php-fpm.d
cp www.conf.default www.conf
管理php-fpm配置:
cd /usr/local/src/php-7.2.4
cp ./sapi/fpm/php-fpm.service 到 /usr/lib/systemd/system/下
也执行以下命令启动php-fpm服务:
cp sapi/fpm/php-fpm.service /usr/local/php/bin/
/usr/local/bin/php-fpm
启动完毕之后,php-fpm服务默认使用9000端口,使用 netstat -tln | grep 9000 可以查看端口使用情况:
配置开机启动php-fpm:
systemctl enable php-fpm
启动php-fpm:
systemctl start php-fpm
查看状态:
systemctl status php-fpm
添加环境变量:
vim /etc/profile
在末尾追加:
export PATH=$PATH:'/usr/local/php/bin/'
保存退出。
source /etc/profile
测试:
php -v
看到php版本信息就表示已经成功了。
如果需要区分web和cli环境,可以将 /usr/local/php/etc/php.ini 复制一份,重命名为php-cli.ini
cp /usr/local/php/etc/php.ini /usr/local/php/etc/php-cli.ini
需要调整配置,就在各自的配置文件中进行调整即可。
设置nginx
nginx配置:
server {
listen 80;
server_name www.demo.com;
#charset koi8-r;
access_log /var/logs/nginx/access.log main;
error_log /var/logs/nginx/error.log;
root /wwwroot;
location / {
index index.php;
try_files $uri /index.php?_RW_=$uri;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /wwwroot$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
修改完这些保存并退出,然后重启nginx:
/usr/local/nginx/nginx -s stop
/usr/local/nginx/nginx
或者
/usr/local/nginx/nginx -s reload
访问网站,如果能正常打开页面,就证明设置成功了,有些时候会遇到一些权限问题,比如我就遇到了缓存目录没有写权限,chmod 755 cache修改目录的权限,然后程序就能正常运行了。
done!
