php安装
# 安装源
# 安装 EPEL 软件包：
sudo yum install epel-release
# 安装 remi 源：
sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
# 安装 yum 扩展包：
sudo yum install yum-utils
# 启用 remi 仓库：
sudo yum-config-manager --enable remi-php72 $ sudo yum update
# 安装 PHP7,2
sudo yum install php72
# 查看安装结果
php72 -v
# 安装 php-fpm 和一些其他模块
sudo yum install php72-php-fpm php72-php-gd php72-php-json php72-php-mbstring php72-php-mysqlnd php72-php-xml php72-php-xmlrpc php72-php-opcache php72-php-devel php72-php-pear
# 设置开机自启
sudo systemctl enable php72-php-fpm.service
# 开启服务
sudo systemctl start php72-php-fpm.service
# 停止服务
sudo systemctl stop php72-php-fpm.service
# 重启服务
sudo systemctl restart php72-php-fpm.service
# 查看状态
sudo systemctl status php72-php-fpm.service
cd /usr/local/nginx/html
vim phpinfo.php
# phpinfo.php
<?php
echo phpinfo();
修改nginx配置
cd /usr/local/nginx/conf
vim nginx.conf
# nginx.conf 找到修改如下
# 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 /scripts$fastcgi_script_name;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# 重启nginx
systemctl restart nginx
#访问 http://服务器ip地址/phpinfo.php
安装swoole扩展(手动)
# 下载 http://pecl.php.net/package/redis
wget http://pecl.php.net/get/swoole-4.4.26.tgz
# 解压
tar zxvf swoole-4.4.26.tgz
cd swoole-4.4.26
# 用phpize生成
/opt/remi/php72/root/usr/bin/phpize
# 进行配置
./configure --with-php-config=/opt/remi/php72/root/usr/bin/php-config
# 编译安装
make && make install
#报错 error: '__builtin_ssubl_overflow' was not declared in this scope。 先升级gcc版本
sudo yum install centos-release-scl
sudo yum install devtoolset-7
scl enable devtoolset-7 bash
#需要注意的是scl命令启用只是临时的，退出shell或重启就会恢复原系统gcc版本。
#如果要长期使用的话：
echo "source /opt/rh/devtoolset-7/enable" >>/etc/profile
#这样退出shell重新打开就是新版的gcc了
#其他版本同理，修改devtoolset版本号即可
# 再执行 make && make install
# 在PHP配置文件php.ini里面加载swoole扩展
cd /etc/opt/remi/php72/php.d/
vim 40-swoole.ini
# 40-swoole.ini
; Enable swoole extension module
extension=swoole.so

:swoole.use_shortname = On
;swoole.unixsock_buffer_size = 8388608
# 重启 sudo systemctl stop php72-php-fpm.service
安装redis扩展
# 搜索扩展
yum search php72 | grep redis
# /etc/opt/remi/php72/php.d/50-redis.ini
# 安装后重启服务 phpinfo查看是否安装成功
sudo yum install php72-php-pecl-redis
#redis.so 扩展存放在 /opt/remi/php72/root/usr/lib64/php/modules/
# 安装swoole4版本扩展
# sudo yum install php72-php-pecl-swoole4
