CentOS7 安装LNMP(Linux+Nginx+MySQL+PHP)搭建自己的博客
一、Nginx安装
安装软件必须遵循 稳定版本 至少选择距离最新版本3~5个月的版本数据库更重要
安装步骤：
mkdir -p /data/tools/ /data/app/ /software/ /data/bin/
yum install -y pcre pcre-devel openssl openssl-devel
useradd www -s /sbin/nologin
cd /data/tools/
wget http://nginx.org/download/nginx-1.14.2.tar.gz
tar -xvf nginx-1.14.2.tar.gz
cd nginx-1.14.2
./configure –user=www –group=www –with-http_ssl_module –with-http_stub_status_module –prefix=/software/nginx-1.14.2/
make &make insatll
ln -s /software/nginx-1.14.2/ /software/nginx
chown -R www:www /software/nginx
检查语法启动：
启动
/software/nginx/sbin/nginx -t
为了管理项目方便一般我们会创建一个专门的文件夹放存放.conf文件
vim nginx.conf
二、MySQL安装
下载MySQL：官网www.mysql.com/，点击Downlosas，翻到网页底部，下载社区版，一路点下去，选择通用Linux，下载64位那个，注意检查MD5
值。
或者直接下载
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz
1、解压压缩包到目标位置
–解压压缩包
tar -zxvf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz -C /software/
cd /software
mv mysql-5.7.25-linux-glibc2.12-x86_64/ mysql
2、创建数据仓库目录
cd mysql
mkdir data
3、改变目录属有者
groupadd mysql
useradd -r -s /sbin/nologin -g mysql mysql -d /software/mysql
chown -R mysql:mysql /software/mysql/
4、配置参数
bin/mysqld –initialize –user=mysql –basedir=/software/mysql –datadir=/software/mysql/data/mysql
5、使用脚本工具生成**文件
bin/mysql_ssl_rsa_setup –datadir=/software/mysql/data/mysql
6、修改系统配置文件
cd support-files/
cp mysql.server /etc/init.d/mysql
7、修改以下内容
[mysqld]
init_connect=\’SET collation_connection = utf8_unicode_ci\’
init_connect=\’SET NAMES utf8\’
character-set-server=utf8
port=3306
datadir=/software/mysql/data/mysql
skip-grant-tables
[[email protected] support-files]# /etc/init.d/mysql start
8、启动mysql
ln -s /software/mysql/bin/mysql /usr/bin/
service mysql start
mysql -hlocalhost -uroot -p
输入生成临时密码ui5QxnNc-F+r
–修改密码
set password for \’root\’@localhost=password(\’[email protected]#\’);
每次登录mysql客户端嫌输绝对路径麻烦，就建一个软连接：ln -s /software/mysql/mysql/bin/mysql /usr/bin/mysql,这样也省去了配PATH路径的麻烦。
mysqld的开机启动，使用chkconfig命令
chkconfig –add mysqld #增加mysqld服务
chkconfig –list #列出所有的系统服务
看一下是不是在所有等级都是打开状态，例如：
chkconfig –level 35 mysqld on
#设定mysqld在等级3和5为开机运行服务
mysql基本命令
连接数据库：mysql -hlocalhost -uroot -p
查看数据库：show databases;
删除数据库：drop database wordpress;
创建数据库：create database wordpress;
查看当前用户：select user();
查看默认的用户：select user,host from mysql.user;
增加用户：grant all on wordpress.* to [email protected]\’localhost\’ identified by\’123456\’;
查看用户管理哪个库的权限：show grants for [email protected]\’localhost\’;
刷新更改：flush privileges;
三、PHP7安装
官网安装方法：
http://php.net/manual/zh/install.unix.nginx.php
编译安装
1.下载php7
wget -O php7.tar.gz http://cn2.php.net/get/php-7.1.20.tar.gz/from/this/mirror
或者直接网页下载
http://php.net/get/php-7.1.20.tar.gz/from/a/mirror
2.解压php7
tar -xvf php7.tar.gz
3.进入php目录
cd /usr/local/src/php-7.1.20
4.安装依赖包
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（如果出现错误，基本都是上一步的依赖文件没有安装所致）
./configure \
–prefix=/software/php \
–with-config-file-path=/etc \
—enable-fpm \
–with-fpm-user=www \
–with-fpm-group=www \
—enable-inline-optimization \

—enable-opcache
报错解决
最实用的解决办法如下:
问题：
1: wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/libmcrypt/libmcrypt-2.5.7.tar.gz
2: tar zxf libmcrypt-2.5.7.tar.gz
3: ./configure –prefix=/usr/local
4: make && make install
问题：configure: error: Don\’t know how to define struct flock on this system, set –enable-opcache=no
解决：解决办法：
vim /etc/ld.so.conf.d/local.conf # 编辑库文件
/usr/local/lib # 添加该行
ldconfig –v # 使之生效
注意事项：
这里添加的库文件路径一定要和你系统平台arch一致，32bit的系统直接添加/usr/local/lib即可，64bit系统要填加/usr/local/lib64.否则依旧会报错，我当时就是添加了/usr/local/lib死活编辑不了，后来更改为/usr/local/lib64才可以。
6.正式安装
make && make install
7.配置环境变量
vi /etc/profile
PATH=$PATH:/usr/local/php/bin
export PATH
source /etc/profile
8.配置php-fpm
cp php.ini-production /usr/local/php/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 /usr/local/php/etc/php-fpm
chmod +x /usr/local/php/etc/php-fpm
ln /usr/local/php/etc/php.ini /etc/php.ini
9、创建www用户
useradd www
10、配置启动项参数
vim /usr/local/php/etc/php-fpm.d/www.conf
pm.max_children = 500
pm.start_servers = 105
pm.min_spare_servers = 10
pm.max_spare_servers = 200
11.启动php-fpm
/usr/local/php/etc/php-fpm start
设置 php-fpm开机启动
cp /usr/local/src/php-5.5.14/sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm #拷贝php-fpm到启动目录
chmod +x /etc/rc.d/init.d/php-fpm #添加执行权限
chkconfig php-fpm on #设置开机启动
service php-fpm start
pkill php-fpm 强制关闭
四、搭建开源博客产品WordPress 注意软件支持的版本
下载：wget https://cn.wordpress.org/wordpress-5.0.3-zh_CN.tar.gz
tar -zxvf wordpress-5.0.3-zh_CN.tar.gz
cd wordpress
cp -a * /mnt/www/wordprees/
chown -R www.www /mnt/www/wordprees/
创建配置文件
