CentOS7之-LNMP环境搭建

环境准备

清空关闭防火墙并关闭selinux

# iptables -F

# systemctl stop firewalld

# systemctl disable firewalld

# vim /etc/selinux/config

改： SELINUX= enforcing

为： SELINUX=disabled

# reboot   #重启系统生效

配置yum源

配置网络yum源

(1)备份 ：

# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

(2)下载新的CentOS-Base.repo 到/etc/yum.repos.d/

# rpm -ivh /mnt/Packages/wget-1.14-15.el7.x86_64.rpm

# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo  #下载配置文件

配置epel源

# yum install epel-release –y

 

部署LNMP环境

LNMP=Linux + Nginx + MySQL + PHP

mysql-boost-5.7.27.tar.gz
nginx-1.17.4.tar.gz

pcre-8.43.tar.gz

php-7.3.10.tar.gz

安装nginx

yum -y install gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel   #安装依赖包

useradd -M -s /sbin/nologin nginx    #创建nginx用户

tar xvf pcre-8.43.tar.gz -C /usr/local/src/    #上传源码包

上传nginx安装包解压安装

tar xvf nginx-1.17.4.tar.gz -C /usr/local/src/

cd /usr/local/src/nginx-1.17.4   

#./configure --prefix=/usr/local/nginx --with-http_dav_module --with-http_stub_status_module --
with-http_addition_module --with-http_sub_module --with-http_flv_module --with-http_mp4_module --with-pcre=/usr/local/src/pcre-8.43 --user=nginx --group=nginx   #配置选项

#make && make install   #编译安装

配置Nginx支持php文件

修改配置文件之前，先备份，养成好习惯,备份nginx.conf

# cp /usr/local/nginx/conf/nginx.conf{,.bak}
# vim /usr/local/nginx/conf/nginx.conf

user nginx nginx;     修改用户为nginx

启用php的支持

 location ~ \.php$ {
  root           html;
  fastcgi_pass   127.0.0.1:9000;
  fastcgi_index  index.php;
  fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
  include        fastcgi_params;

  }

启动nginx服务

# /usr/local/nginx/sbin/nginx

编辑配置环境变量

# vim /etc/profile.d/nginx.sh

export PATH=/usr/local/nginx/sbin:$PATH

配置服务开机自动启动

配置开机自动启动

# chmod +x /etc/init.d/nginx

# chkconfig --add nginx

# chkconfig nginx on

 

安装MySQL 5.7

卸载系统自带的mysql和boost

# yum -y remove mysql mariadb-*

# yum -y remove boost-*

开始安装

yum install -y cmake make gcc gcc-c++ bison ncurses ncurses-devel  #安装依赖包

# groupadd mysql
# useradd -M -s /sbin/nologin -r -g mysql mysql  #添加用户和组

上传安装包并解压

# tar xf mysql-boost-5.7.27.tar.gz -C /usr/local/src/

# cd /usr/local/src/mysql-5.7.27/

规划安装目录：

   安装目录：/var/lib/mysql

   数据目录：/val/lib/mysql/data

mkdir -p /var/lib/mysql/data
chown -R mysql:mysql /var/lib/mysql   #授权目录mysql权限

编译安装

配置环境变量

# vim /etc/profile.d/mysql.sh

export PATH=/var/lib/mysql/bin:$PATH  #添加path路径，让系统读到mysql命令

#source /etc/profile.d/mysql.sh  #使其mysql.sh生效

修改mysql目录权限

# chown -R mysql:mysql /var/lib/mysql

生成服务启动脚本

# cp /var/lib/mysql/support-files/mysql.server /etc/init.d/mysqld

# chowd +x /etc/init.d/mysqld

初始化数据库

# /var/lib/mysql/bin/mysqld --initialize --user=mysql --basedir=/var/lib/mysql --datadir=/var/lib/mysql/data

启动服务

 # /etc/init.d/mysqld start

Starting MySQL.. SUCCESS!

修改初始登录密码

Mysql5.7初始安装后，第一次登录需要查询一下密码

# grep "password" /var/log/mysql-error.log
2019-10-25T09:00:27.826152Z 1 [Note] A temporary password is generated for root@localhost: muHyi?fKy5rc
登录修改密码

# mysql -u root -p

Enter password: muHyi?fKy5rc

mysql> alter user 'root'@'localhost' identified by '123456';

mysql>flush privileges;

 

 编译安装PHP

安装所需依赖包

# yum -y install php-mcrypt  libmcrypt  libmcrypt-devel php-pear libxml2 libxml2-devel curl curl-d
evel libjpeg libjpeg-devel libpng libpng-devel freetype-devel

上传并解压PHP安装包

 # tar xf php-7.3.10.tar.gz -C /usr/local/src/

# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/ --enable-fpm  --with
-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --disable-fileinfo --enable-maintainer-zts

修改配置

# cp /usr/local/src/php-7.3.10/php.ini-production /usr/local/php/php.ini   #复制php配置文件到安装目录
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf   #复制模板配置文件为php-fpm的配置文件

修改： vim /usr/local/php/etc/php-fpm.conf
pid = run/php-fpm.pid #取消前面的分号

cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
修改：vim /usr/local/php/etc/php-fpm.d/www.conf
user = www #设置php-fpm运行账号为www
group = www #设置php-fpm运行组为www

设置php-fpm开机启动

cp /usr/local/src/php-7.3.10/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm #复制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 #启动php-fpm

重启php和nginx。
service php-fpm restart
service nginx restart

测试：

在web目录：/usr/local/nginx/html中新建一个phpinfo的php文件，在浏览器中查看。
