Centos7 用yum命令安装LAMP环境（php+Apache+Mysql）以及php扩展

1、yum -y update    // 更新系统

　　1.1）yum -y install gcc g++ gcc-c++ make kernel-devel kernel-headers

　　1.2）vi /etc/selinux/config　　#  禁止SELINUX

　　1.3）设置SELINUX=disabled

　　1.4）重启系统

2、安装mysql

2.1）yum -y install mariadb-client mariadb-server mariadb-devel

2.2）启动：systemctl start mariadb.service

2.3）设置开机自启：systemctl enable mariadb

2.4）设置root密码：

　　① systemctl stop mariadb.service

　　② mysqld_safe --skip-grant-tables

　　③ mysql -u root（另开shell）

　　④ use mysql;

　　⑤ update user set password=password("123456") where user='root';

　　⑥ delete from user where user = '';

　　⑦ flush privileges;

2.5）设置root远程访问：

　　① use mysql;

　　② update user set host='%' where user='root' and host='localhost';

　　③ flush privileges;

　　④ exit;

　　⑤ systemctl restart mariadb.service

　　⑥ firewall-cmd --zone=public --add-port=80/tcp --permanent    #添加80端口

　　⑦ firewall-cmd --zone=public --add-port=3306/tcp --permanent    #添加3306端口

　　⑧ firewall-cmd --reload    #重新启动防火墙

3、安装apache

3.1）yum -y install httpd

3.2）启动：systemctl start httpd.service

3.3）设置开机自启：systemctl enable httpd

3.4）配置虚拟主机：在/etc/httpd/conf.d/目录下建新vhost.conf，新增内容：

　　　　<VirtualHost *:>
　　　　　　DocumentRoot "/var/www/html/"
　　　　　　ServerName 192.168.8.100
　　　　　　ErrorLog "/var/log/httpd/error.log"
　　　　　　CustomLog "/var/log/httpd/access.log" common
　　　　</VirtualHost>

　　　　<VirtualHost *:>
　　　　　　DocumentRoot "/var/www/html/CodeIgniter-3.1.2/"
　　　　　　ServerName www.100ci.com
　　　　　　ErrorLog "/var/log/httpd/100ci-error.log"
　　　　　　CustomLog "/var/log/httpd/100ci-access.log" common
　　　　</VirtualHost>

附一：yum安装nginx

　　# rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

　　# yum info nginx

　　# yum install -y nginx

　　# systemctl start nginx

　　# systemctl enable nginx

附二：安装 nginx 也相当简单，查看官网说明文档 http://nginx.org/en/linux_packages.html#stable

　　 1）[root@localhost ~] vi /etc/yum.repos.d/nginx.repo

　　2）复制如下内容到刚才新建的文件中

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/　　# 因为我的系统是centos7
gpgcheck=
enabled=

　　3）yum -y install nginx

　　4）yum start nginx

　　5）yum enable nginx

附三：ngnix修改配置文件支持php　　

server {
    listen         ;
    server_name    localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;
    root   /var/www/;    # 把root从localhost中拿出来，不然$document_root找不到会报404

    location / {
        index  index.php index.html index.htm;
    }

    #error_page                /.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page        /50x.html;
    location = /50x.html {
        root   /var/www/;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:
    #
    location ~* \.php$ {
        fastcgi_index   index.php;
        fastcgi_pass    127.0.0.1:;
        include         fastcgi_params;
        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

附四：修改/etc/php-fpm.d/www.conf  文件

user = nginx　　　＃　由apache改为nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx    # 由apache改为nginx
