实验部署环境

服务器类型 IP地址 应用 操作系统
nginx 192.168.170.16 nginx centos7/redhat7
mysql 192.168.170.14 mysql centos7/redhat7
php 192.168.170.13 php centos7/redhat7
  • 注意:本次实验,三台主机都关闭防护墙,selinux为disable状态
  • 关闭防火墙和selinux
    systemctl stop firewalld
    systemctl disable firewalld
    getenforce
    Disabled

nginx 安装

  • 创建系统用户、组nginx
[root@localhost ~]#groupadd -r nginx
[root@localhost ~]# useradd -r -M -s /sbin/nologin  -g nginx  nginx

  • 安装依赖环境
[root@localhost ~]# yum -y install pcre-devel openssl openssl-devel gcc gcc-c++
安装过程略....
[root@localhost ~]# yum -y groups mark install 'Development Tools'  #如果你安装虚拟机时,安装过开发工具,此步骤无需操作
Loaded plugins: product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
Marked install: Development Tools

  • 创建日志存放目录
[root@localhost ~]# mkdir -p /var/log/nginx
[root@localhost ~]# chown -R nginx.nginx /var/log/nginx


  • 下载nginx
[root@localhost ~]# cd /usr/src/
[root@localhost src]# wget http://nginx.org/download/nginx-1.12.0.tar.gz
…………
  • 编译安装
[root@localhost src]# ls
debug  kernels  nginx-1.12.0.tar.gz
[root@localhost src]# tar xf nginx-1.12.0.tar.gz
[root@localhost src]# cd nginx-1.12.0
[root@localhost nginx-1.12.0]# ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-debug \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--http-log-path=/var/log/nginx/access.log \
--error-log-path=/var/log/nginx/error.log

[root@localhost nginx-1.12.0]# make -j $(grep 'processor' /proc/cpuinfo | wc -l) && make install
安装过程略....

nginx安装后配置

  • 配置环境变量
[root@localhost ~]# echo 'export PATH=/usr/local/nginx/sbin:$PATH' > /etc/profile.d/nginx.sh
[root@localhost ~]# . /etc/profile.d/nginx.sh

  • 服务控制方式,使用nginx命令
    -t  //检查配置文件语法
    -v  //输出nginx的版本
    -c  //指定配置文件的路径
    -s  //发送服务控制信号,可选值有{stop|quit|reopen|reload}
  
  • 启动nginx
[root@localhost ~]# nginx
[root@localhost ~]# ss -antl
State      Recv-Q Send-Q   Local Address:Port                  Peer Address:Port
LISTEN     0      128                  *:80                               *:*
LISTEN     0      128                  *:22                               *:*

[root@localhost local]# ln -sv mysql-5.7.22-linux-glibc2.12-x86_64/ mysql
‘mysql’ -> ‘mysql-5.7.22-linux-glibc2.12-x86_64/’

  • 修改目录/usr/local/mysql的属主属组
[root@localhost ~]# chown -R mysql.mysql  /usr/local/mysql

  • 添加环境变量
[root@localhost ~]# ls /usr/local/mysql
bin  COPYING  docs  include  lib  man  README  share  support-files

[root@localhost ~]#  #这个临时密码是随机的

  • 生成配置文件
[root@localhost ~]# cat > /etc/my.cnf < [mysqld]
> basedir = /usr/local/mysql
> datadir = /opt/data
> socket = /tmp/mysql.sock
> port = 3306
> pid-file = /opt/data/mysql.pid
> user = mysql
> skip-name-resolve
> EOF

[root@localhost ~]# cat /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql
datadir = /opt/data
socket = /tmp/mysql.sock
port = 3306
pid-file = /opt/data/mysql.pid
user = mysql
skip-name-resolve


-配置服务启动脚本

[root@localhost ~]# cp -a /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@localhost ~]# sed -ri 's#^(basedir=).*#\1/usr/local/mysql#g' /etc/init.d/mysqld
[root@localhost ~]# sed -ri 's#^(datadir=).*#\1/opt/data#g' /etc/init.d/mysqld

  • 启动脚本
[root@localhost ~]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/opt/data/localhost.localdomain.err'.
 SUCCESS! 
[root@localhost ~]# 

  • 使用临时密码登录
  • 修改数据库密码
[root@localhost ~]# /usr/local/mysql/bin/mysql -uroot -p

安装后配置

[root@localhost ~]# echo 'export PATH=/usr/local/php7/bin:$PATH' > /etc/profile.d/php7.sh
[[root@localhost ~]#source /etc/profile.d/php7.sh
[root@localhost php-7.2.8]# which php

  • 配置php-fpm(必须在此目录下操作)
[root@localhost php-7.2.8]# cp php.ini-production /etc/php.ini
[root@localhost php-7.2.8]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-7.2.8]# chmod +x /etc/rc.d/init.d/php-fpm
[root@2localhost php-7.2.8]# cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
[root@localhost php-7.2.8]# cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf

  • 编辑php-fpm的配置文件(/usr/local/php7/etc/php-fpm.conf)最后添加以下几行内容:
[root@ php-7.2.8]# vim /usr/local/php7/etc/php-fpm.conf
pm.max_children = 50        # 最多同时提供50个进程提供50个并发服务
pm.start_servers = 5        # 启动时启动5个进程
pm.min_spare_servers = 2    # 最小空闲进程数
pm.max_spare_servers = 8    # 最大空闲进程数
[root@localhost ~]# tail /usr/local/php7/etc/php-fpm.conf
; file.
; Relative path can also be used. They will be prefixed by:
;  - the global prefix if it's been set (-p argument)
;  - /usr/local/php7 otherwise
include=/usr/local/php7/etc/php-fpm.d/*.conf
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 8

  • 启动php-fpm
[root@localhost ~]# service php-fpm start
Starting php-fpm  done

  • 查看9000端口是否启动
[root@localhost ~]# ss -antl
