1，关闭Disable Selinux
sestatus //查询状态 sed -i 's/(^SELINUX=).*/SELINUX=disabled/' /etc/selinux/config //设置关闭
配置firewall
yum -y install firewalld
systemctl enable/disable firewalld
systemctl start firewalld
firewall-cmd --permanent --zone=public --add-service={http,https}
firewall-cmd --permanent --zone=public --add-port={5060,5061,5080,5081}/tcp
firewall-cmd --permanent --zone=public --add-port={5060,5061,5080,5081}/udp
firewall-cmd --permanent --zone=public --add-port=16384-32768/udp
firewall-cmd --reload
关闭IPv6
yum install ifconfig
ifconfig命令查看网卡信息，如果出现inet6 fe80::20c:29ff:fed0:3514，说明机器开启了ipv6
编辑/etc/sysctl.conf配置，增加net.ipv6.conf.all.disable_ipv6=1
编辑/etc/sysconfig/network配置，增加 NETWORKING_IPV6=no
编辑/etc/sysconfig/network-scripts/ifcfg-xxxx，确保IPV6INIT=no，ifcfg-xxxx是根据自己机器的
systemctl disable ip6tables.service //关闭防火墙的开机自启动
执行sysctl -p或者reboot重启命令
重新配置时区
tzselect // FIND YOUR TIMEZONE
timedatectl set-timezone America/Vancouver //SET TIMEZONE EXAMPLE
timedatectl status //CHECK TIMEZONE
安装PHP7.4
1、配置安装资源
yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum -y install yum-utils
sudo yum-config-manager --enable remi-php74
sudo yum update#启用PHP remi-7.4模块后，即可使用以下命令继续并安装PHP。 这还将安装许多其他软件包，例如Apache和Nginx模块
yum -y install php php-cli php-common php-fpm php-mysql php-cgi php-mbstring php-gd php-process php-mcrypt php-soap libjpeg* php-pear php-xml php-devel php-memcached php-redis php-gearman php-pecl-mongodb
yum -y install gearmand libgearman-devel
yum -y install redis memcached
查看安装版本
php -v
#设置开机启动、运行服务：
systemctl enable php-fpm
systemctl start php-fpm
