Centos7 yum安装LNMP

1、Centos7系统库中默认是没有nginx的rpm包的，所以我们需要先更新下rpm依赖库

 (1)：使用yum安装nginx，安装nginx库

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

 (2)：使用下面命令安装nginx

yum -y install nginx

 (3)：启动nginx

systemctl start nginx   #centos7

查看nginx版本
nginx -v

  nginx version: nginx/1.18.0

 (4)：防火墙允许通过80端口-

 (5)：重启防火墙

systemctl start firewalld

 (6)：访问网站，输入服务器ip地址，查看是否出现 'Welcome To Nginx'，如果想更改网站根目录，修改地址：vim /etc/nginx/conf.d/default.conf，修改Root 后面的路径

 

2、安装Mysql，先更新yum源

 (1)：yum源下载地址，根据自己需要的版本选择相应的源

https://dev.mysql.com/downloads/repo/yum/

  (2)：我们版本是6.x的，所以选择linux 6 下载

wget https://repo.mysql.com//mysql57-community-release-el6-11.noarch.rpm

  (3)：安装mysql的yum源

rpm -Uvh mysql57-community-release-el6-11.noarch.rpm
或
yum -y localinstall mysql57-community-release-el6-11.noarch.rpm

  (4)：查看是否配置mysql源成功

在/etc/yum.repos.d下面

(5)：安装Mysql

yum -y install mysql-community-server
#时间有点长，稍微等一下

 (6)：开始mysql服务

service mysqld start

  (7)：Mysql安装成功之后，会自动创建root的密码，存储在/var/log/mysqld.log，可以通过以下命令来查看

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

  (8)：登录mysql，修改密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Wang123!';

  (9)：开启远程链接，iptables开放3306端口

firewall-cmd --zone=public --add-port=3306/tcp --permanent 

vim /etc/sysconfig/iptables   （我自己没找到这个文件，所以用上面命令开放了80和3306的端口）

  (10)：重启防火墙使iptables生效

systemctl start firewalld

3、安装PHP（php-5.6）(根据自己要安装的版本进行下载源码包 https://www.php.net/releases/)

（1）cd /usr/local/src/

（2）下载：wget http://cn2.php.net/distributions/php-5.6.36.tar.gz

（3） 解压源码包，创建账号

    tar zxf php-5.6.36.tar.gz

    useradd -s /sbin/nologin php-fpm

（4） 新建目录：

    mkdir  /usr/local/php-fpm/etc

（5）配置编译选项：#多了--enable-fpm，如果不加该参数，则不会有php-fpm执行文件生成，更不能启动php-fpm服务

./configure \
> --prefix=/usr/local/php-fpm \
> --with-config-file-path=/usr/local/php-fpm/etc \
> --enable-fpm \
> --with-fpm-user=php-fpm \
> --with-fpm-group=php-fpm \
> --with-mysql=/usr/local/mysql \
> --with-mysql-sock=/tmp/mysql.sock \
> --with-libxml-dir \
> --with-gd \
> --with-jpeg-dir \
> --with-png-dir \
> --with-freetype-dir \
> --with-iconv-dir \
> --with-zlib-dir \
> --with-mcrypt \
> --enable-soap \
> --enable-gd-native-ttf \
> --enable-ftp \
> --enable-mbstring \
> --enable-exif \
> --disable-ipv6 \
> --with-pear \
> --with-curl \
> --with-openssl
