linux centos8 安装php nginx mysql 运行phpcms网站

重新换vps，用centos8，重新配置系统环境，记下笔记：

安装nginx与php

首先安装nginx php ,安装默认版本的nginx，php默认安装7 

yum install nginx php  

系统罗列安装详细信息，输入yes即可

nginx状态设置

启动nginx

systemctl start nginx.service

查看nginx状态

systemctl status nginx

设置开机启动

 systemctl enable nginx.service

显示 enbaled 则设置开机启动成功

systemctl is-enabled nginx.service;echo $? 

php状态设置

启动php

systemctl start php-fpm

查看php 当前版本

php -v

设置php开机启动

systemctl enable php-fpm

 如果要运行phpcms 还要安装gd json mysql库

 yum install  php-gd php-msyql php-json

如果不知道名字，yum search  php ，查看相关扩张库

安装以下扩张库 

yum -y install php-json php-xml  php-mysqlnd php-mbstring  php-common  php-gd 

##  yum -y install php72w-cli php72w-common php7php2w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml

 

如果需要安装php5.6

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

yum install php56w php56w-opcache  php56w-fpm

查看php版本

php -V

mysql安装

centos 默认安装的mysql8.0，我希望安装5.6，需要收手工安装。

首先参考下网上的方法：

centos7 安装mysql5.6 https://www.cnblogs.com/lulin9501/p/11069093.html

 

需要编译，放弃，推荐，参考此篇方法，安装。精炼如下：

按照此篇方法 安装，CentOS 7系统安装nginx+php+mysql https://blog.csdn.net/YZJ0517/article/details/85542304

启动mysql，报 Failed to start mysqld.service: Unit mysqld.service not found. 错误

推荐： CentOS7下使用YUM安装MySQL5.6 https://blog.csdn.net/pengjunlee/article/details/81212250

查看是否安装MySQL

rpm -qa | grep mysql

下载安装包文件

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

安装mysql-community-release-el7-5.noarch.rpm包

rpm -ivh mysql-community-release-el7-5.noarch.rpm

查看可用安装包

yum repolist all | grep mysql

安装mysql

yum install mysql-server

检查mysql是否安装成功。

rpm -qa | grep mysql

启动 mysql 服务 

systemctl start mysqld.service

 

设置密码

mysql -u root
mysql> use mysql;
mysql> update user set password=PASSWORD("这里输入root用户密码") where User='root';
mysql> flush privileges;

设置mysql字符集

character_set_server = utf8

default-character-set = utf8

或者 vim /etc/my.cnf

设置为 ：

character_set_server=utf8
init_connect='SET NAMES utf8'
