1. 下载nginx:http://nginx.org/en/download.html

2. 在usr/local文件夹中新建一个lnmp的文件夹，下载nginx压缩包并解压

[root@VM_48_141_centos ~]# cd usr/local

[root@VM_48_141_centos local]# mkdir lnmp

[root@VM_48_141_centos local]# cd lnmp

[root@VM_48_141_centos lnmp]# wget http://nginx.org/download/nginx-1.12.2.tar.gz

[root@VM_48_141_centos nginx-1.12.2]# ./configure --prefix=/usr/local/lnmp/nginx

出错

原因：没有gcc的编译库

解决办法：[root@VM_48_141_centos nginx-1.12.2]# yum install gcc gcc-c++ kernel-devel

继续，又出错

原因：没有正则库

解决办法：[root@VM_48_141_centos nginx-1.12.2]# yum install pcre-devel

继续，又出错

原因：没有zlib库

解决办法： [root@VM_48_141_centos nginx-1.12.2]# yum install -y zlib-devel

继续，OK

3.编译并安装 [root@VM_48_141_centos nginx-1.12.2]# make && make install

4启动nginx

[root@VM_48_141_centos lnmp]# cd Nginx

进入刚才自定义的安装目录Nginx 有4个文件爱夹

conf:配置文件 html:网页文件 logs:日志文件 sbin:主要进程文件

[root@VM_48_141_centos Nginx]# ./sbin/nginx

在浏览器中访问：

关闭Nginx：[root@VM_48_141_centos Nginx]# kill -INT 28024

查看nginx主进程号：[root@VM_48_141_centos Nginx]# ps aux|grep nginx

中间用到的命令

grep 'nginx' /etc/group

awk -F":" '{print $1"\t\t"$4}' /etc/passwd | grep '1000'

Nginx.Conf

# }

}

二. 安装mysql

[root@VM_48_141_centos logs]# yum -y install mysql-server mysql mysql-devel

然后花了一下午在改mysql,装的不是mysql，而是mariadb

1.卸载：yum autoremove mysql -y

2.wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

3.yum localinstall mysql57-community-release-el7-11.noarch.rpm

4.yum repolist enabled | grep "mysql.*-community.*"

5.yum install mysql-community-server -y

6. 启动mysql并查看其状态

命令：systemctl start mysqld

命令：systemctl status mysqld

7. 设置mysql为系统服务，随系统启动而启动

命令：systemctl enable mysqld

命令：systemctl daemon-reload

8. 查看mysql下root账号的默认密码

mysql5.7安装完成之后，在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码，然后登录mysql。

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

其中Jb2h<%lp9itY部分就是默认密码

9.2. 修改my.cnf文件(/etc/my.cnf)

9.2.1. 修改密码策略

mysql的密码策略分为三种：

0或LOW：Length

1或MEDIUM：Length; numeric, lowercase/uppercase, and special characters

2或STRONG：Length; numeric, lowercase/uppercase, and special characters; dictionary file

在mysql的配置文件my.cnf文件中增加如下设置

#如果不需要密码策略，禁用密码策略
validate_password = off

# 密码选择策略 0-LOW，1-MEDIUM，2-STRONG需要提供密码字典文件
validate_password_policy = 0

9.2.2. 修改字符编码为utf8

在my.cnf中的[mysqld]下增加如下配置

character_set_server = utf8
init_connect = 'SET NAMES utf8'

命令：systemctl restart mysqld

10. 登录mysql

命令：mysql -uroot -p

输入密码：默认为刚才查到的Jb2h<%lp9itY

11. 修改密码

命令：ALTER USER 'root'@'localhost' IDENTIFIED BY '12345678';
或命令：set password for 'root'@'localhost'=password('12345678');

12. 添加远程账户

命令：GRANT ALL PRIVILEGES ON *.* TO 'remote'@'%' IDENTIFIED BY '12345678' WITH GRANT OPTION;

命令：FLUSH PRIVILEGES; 使设置生效

三．安装PHP

1. 下载地址：http://cn2.php.net/distributions/php-7.1.11.tar.gz

wget http://cn2.php.net/distributions/php-7.1.11.tar.gz

tar -zxvf php-7.1.11.tar.gz

..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

./configure --prefix=/usr/local/lnmp/PHP \--with-config-file-path=/etc \--enable-fpm \--with-fpm-user=nginx \--with-fpm-group=nginx \--enable-inline-optimization \--disable-debug \--disable-rpath \--enable-shared \--enable-soap \--with-libxml-dir \--with-xmlrpc \--with-openssl \--with-mcrypt \--with-mhash \--with-pcre-regex \--with-sqlite3 \--with-zlib \--enable-bcmath \--with-iconv \--with-bz2 \--enable-calendar \--with-curl \--with-cdb \--enable-dom \--enable-exif \--enable-fileinfo \--enable-filter \--with-pcre-dir \--enable-ftp \--with-gd \--with-openssl-dir \--with-jpeg-dir \--with-png-dir \--with-zlib-dir \--with-freetype-dir \--enable-gd-native-ttf \--enable-gd-jis-conv \--with-gettext \--with-gmp \--with-mhash \--enable-json \--enable-mbstring \--enable-mbregex \--enable-mbregex-backtrack \--with-libmbfl \--with-onig \--enable-pdo \--with-mysqli=mysqlnd \--with-pdo-mysql=mysqlnd \--with-zlib-dir \--with-pdo-sqlite \--with-readline \--enable-session \--enable-shmop \--enable-simplexml \--enable-sockets \--enable-sysvmsg \--enable-sysvsem \--enable-sysvshm \--enable-wddx \--with-libxml-dir \--with-xsl \--enable-zip \--enable-mysqlnd-compression-support \--with-pear \--enable-opcache

.编译与安装

# make && make install

这里要make好久，要耐心一下

.添加 PHP命令到环境变量

# 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

# source /etc/profile

查看环境变量

# echo $PATH

查看php版本

# php -v

配置php-fpm

# cp php.ini-production /etc/php.ini

# 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

# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

# chmod +x /etc/init.d/php-fpm

启动php-fpm

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

.重启nginx

# service nginx reload

<?php

phpinfo();
