Centos 7 PHP7.1环境配置 LNMP

首先更新系统软件 yum update
安装gcc编译器 yum install gcc && yum install gcc-c++

编译安装php7.1.8

1.下载php7源码包

1	$ cd /root & wget -O php7.tar.gz http://am1.php.net/get/php-7.1.8.tar.gz/from/this/mirror

2.解压源码包

1	$ tar -xzvf php7.tar.gz

3.进入PHP目录

1	$ cd php-7.1.8

4.安装php依赖包

$ yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

5.编译配置，这一步我们会遇到很多configure error，我们一一解决，基本都是相关软件开发包没有安装导致

$ ./configure \

--with-config-file-path=/etc \

1	$ make && make install

这里要make好久，要耐心一下

7.添加 PHP 命令到环境变量

1	$ vim /etc/profile

在末尾加入

PATH=$PATH:/usr/local/php/bin

export PATH

要使改动立即生效执行

1	$ ./etc/profile

或

1	$ source /etc/profile

查看环境变量

1	$ echo $PATH

查看php版本

$ php -v

8.配置php-fpm

1	$ cp php.ini-production /etc/php.ini

1 2	$ cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf $ cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

1	$ cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

1	$ chmod +x /etc/init.d/php-fpm

9.启动php-fpm

1	$ /etc/init.d/php-fpm start

$ /etc/init.d/php-fpm start

安装Nginx

1.安装nginx源

1	$ yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.安装nginx

1	$ yum install nginx

3.启动nginx

1	$ service nginx start

Redirecting to /bin/systemctl start nginx.service

4.访问http://你的ip/

1	如果成功安装会出来nginx默认的欢迎界面

安装MySQL5.7.*

1.安装mysql源

1	$ yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm

2.安装mysql

1	$ yum install mysql-community-server

确认一下mysql的版本，有时可能会提示mysql5.6

3.安装mysql的开发包，以后会有用

1	$ yum install mysql-community-devel

4.启动mysql

1	$ service mysqld start

Redirecting to /bin/systemctl start mysqld.service

5.查看mysql启动状态

1	$ service mysqld status

出现pid

证明启动成功

6.获取mysql默认生成的密码

1	$ grep 'temporary password' /var/log/mysqld.log

7.换成自己的密码

1	$ mysql -uroot -p

8. 更换密码

1	mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass666!';

注意:本地可以连接MySQL服务器,远程就不行.

mysql -uroot -p
use mysql;
Grant all on *.* to 'root'@'%' identified by 'root用户的密码' with grant option;
flush privileges;
然后用以下命令查看哪些用户和host可以访问，%代表任意ip地址

select user,host from user;

php和Nginx互通

修改文件

1	$ vim /etc/nginx/conf.d/sui.conf

配置文件

server
{
    listen       80;
    server_name  localhost;
    #charset koi8-r;
    access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.php 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   /usr/share/nginx/html;
    }

    # 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$ {
        root           /usr/share/nginx/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

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

编译安装php扩展

1.查看自己服务器对象php版本

php -v

2.根据版本下载PHP源代码

1	$ wget -O php7.tar.gz http://am1.php.net/get/php-7.1.8.tar.gz/from/this/mirror

3、解压源码压缩包

1	$ tar -zxvf php-7.1.8.tar.gz

4、进入源码中的ext/pcntl目录

1	cd pphp-7.1.8/ext/pcntl/

5、运行 phpize 命令

phpize

如果报错:
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

注:如果报错,写绝对路径:sudo /usr/local/php/bin/phpize

1 2	yum install m4 yum install autoconf

6、运行 configure命令

1	./configure

7、makefile

1	make && make install

8.配置ini文件

1	通过运行 php --ini查找php.ini文件位置，然后在文件中添加extension=pcntl.so

也可以使用pecl 安装

1	pecl install memcached
