CentOS7下搭建LNMP记录

OS:使用虚拟机最小化安装的CentOS 7系统；配置好防火墙，SELINUX，YUM源，IP地址等。

0、因为采用了最小化安装系统，所缺少的包比较多，必要工具先安装一下

 yum install gcc gcc-c++ wget vim lrzsz

数据库安装

一、删除系统中已存在的MySQL

 ##删除MySQL的lib库，服务文件
 yum remove  mysql mysql-server mysql-libs mysql-server

 ##查找MySQL的残留文件
 find / -name mysql

 ##如果存在残留文件，将其删除
 rm -rf *mysql* 

二、删除系统中已存在的MySQL安装包

 ##查找是否有mysql安装包
 rpm -qa | grep -i mysql

 ##如果有，则删除安装包
 yum -y remove mysql-libs*

三、安装新mysql5.6.19（可根据自己需求选择）

 ##添加依赖应用
 yum install -y gcc gcc-c++ autoconf automake zlib* libxml*  libtool-ltdl-devel

 ##安装 cmake 及相关软件 ncurses 和 bison
 wget http://www.cmake.org/files/v3.0/cmake-3.0.2.tar.gz  #可自选方式
 tar zxvf cmake-3.0..tar.gz
 cd cmake-3.0.
 ./bootstrap
 make
 make install

 yum install -y ncurses-devel*
 yum install -y bison

 ##创建 mysql 用户， 创建数据库目录和权限
 groupadd mysql
 useradd -g mysql mysql
 mkdir -p  /data/mysql
 chown -R root:mysql /data/mysql

 ##下载 mysql 源码并且编译
 wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.20.tar.gz
 tar xzfv mysql-5.6..tar.gz
 cd mysql-5.6.
 cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/etc/

 gmake
 gmake install

 ##配置 mysql
 cd /usr/local/mysql
 cp ./support-files/my-default.cnf /etc/my.cnf

 vim /etc/my.cnf
 #在 [mysqld] 段增加
 datadir = /data/mysql
 wait-timeout =
 max_connections =
 max_connect_errors =
 default-storage-engine = MyISAM

 #在 [mysqld] 段修改
 max_allowed_packet = 16M 

 #保存退出编辑

 ##初始化数据库
 ./scripts/mysql_install_db --datadir=/data/mysql --basedir=/usr/local/mysql  --defaults-file=/etc/my.cnf --user=mysql

 cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld

 chmod  /etc/rc.d/init.d/mysqld

 chkconfig --add mysqld

 ##设置启动脚本变量，编辑 /etc/rc.d/init.d/mysqld
 vim /etc/rc.d/init.d/mysqld
 basedir=/usr/local/mysql
 datadir=/data/mysql 

 ##设置变量环境
 echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile （永久生效）
 export PATH=$PATH:/usr/local/mysql/bin （当前生效）

 cd bin
 #启动服务
 service mysqld start

 ##设置数据库管理员root密码
 mysqladmin -u root password ''
 service mysqld restart

 ##进入Mysql 

 mysql -u root -p

安装php5.6.0

 ##添加依赖应用
 yum install -y gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libpng libpng-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses curl openssl-devel gdbm-devel db4-devel libXpm-devel libX11-devel gd-devel gmp-devel readline-devel libxslt-devel expat-devel xmlrpc-c xmlrpc-c-devel curl-devel

 ##安装加密扩展库
 cd /usr/local/src/
 wget libmcrypt-2.5..tar.gz
 tar zxvf libmcrypt-2.5..tar.gz
 cd libmcrypt-2.5.
 ./configure
 make
 make install

 cd ../
 wget http://cn2.php.net/distributions/php-5.6.0.tar.gz
 tar zxvf php-5.6..tar.gz
 cd php-5.6.

 make
 make test
 make install

 cd /usr/local/php-5.6./etc/
 cp php-fpm.conf.default php-fpm.conf

 /usr/local/php-5.6./sbin/php-fpm    ##启动

 ##修改FPM 配置文件php-fpm.conf
 vi php-fpm.conf
 pm.max_children =
 pm.start_servers =
 pm.min_spare_servers =
 pm.max_spare_servers =
 pm.max_requests =
 ##去掉分号

 ln -s /usr/local/php-5.6./sbin/php-fpm /bin/php-fpm
 cp /usr/local/src/php-5.6./php.ini-production /usr/local/php-5.6./lib/php.ini

 ##php-fpm安装完成

安装nginx1.7.5

 cd /usr/local/src/
 wget http://nginx.org/download/nginx-1.7.5.tar.gz

 useradd www
 ##添加www nginx运行账户

 usermod -s /sbin/nologin -g www www
 ##将www加入www组并禁止www登录shell

 tar zxvf nginx-1.7..tar.gz

 cd nginx-1.7.
 ./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --without-http_rewrite_module --with-http_ssl_module --with-pcre

 make && make install

 /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
 ##启动nginx,nginx启动成功

 /usr/local/nginx/sbin/nginx -s reload
 ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx

 ##修改nginx配置文件，根据需要修改对应文件

 vi /usr/local/nginx/conf/nginx.conf
 user nobody;#去掉前面,及找到如下部分取消其前的注释，并修改$document_root

 location ~ \.php$ {
             root           html;
             fastcgi_pass   127.0.0.1:;
             fastcgi_index  index.php;
             fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
             include        fastcgi_params;
         }

 nginx -s reload

 cd /usr/local/nginx/html
 vi info.php
 <?php
 phpinfo();
