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-header
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 mariad
2.4）设置root密码：
① systemctl stop mariadb.service
② mysqld_safe --skip-grant-table
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 privilege
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 privilege
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 *:80> DocumentRoot "/var/www/html/" ServerName 192.168.8.100 ErrorLog "/var/log/httpd/error.log" CustomLog "/var/log/httpd/access.log" common </VirtualHost> <VirtualHost *:80> 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/$basearch/ # 因为我的系统是centos7 gpgcheck=0 enabled=1
3）yum -y install nginx
4）yum start nginx
5）yum enable nginx
附三：ngnix修改配置文件支持php
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;root /var/www/; # 把root从localhost中拿出来，不然$document_root找不到会报404
location / {
index index.php index.html index.htm;
}
#error_page 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 /var/www/;
}
# 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$ {
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
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

4、安装php7
4.1）请参考 https://webtatic.com/packages/php71/
4.2）rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
4.3）rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
4.4） yum -y install php71w php71w-opcache php71w-common php71w-fpm php71w-gd php71w-mbstring php71w-mcrypt php71w-odbc php71w-pecl-redis php71w-pecl-memcached php71w-mysqlnd php71w-devel
4.5）安装完php，重启httpd，systemctl restart httpd
4.6）如果php中有冲突的包，执行yum -y remove 包名
5、安装phpredis、swoole扩展
