Centos7.5编译安装搭建LNMP环境

环境介绍

[root@instance-9a809cx7 ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core) 
[root@instance-9a809cx7 ~]# 

一、Nginx安装
1、检查是否安装wget，如果没有安装就使用yum安装

[root@instance-9a809cx7 ~]# rpm -qa wget
wget-1.14-15.el7_4.1.x86_64
[root@instance-9a809cx7 ~]# 

2、安装编译器

yum install gcc gcc-c++

3、安装nginx依赖的软件
nginx中的rewrite module、gzip module、Http SSL module需要安装PCRE、zlib、OpenSSL,这里编译安装也可以使用yum安装,命令如下，这里用的是编译安装

yum -y install pcre pcre-devel zlib zlib-devel openssl openssl-devel

3.1、zlib源码安装
解压、编译安装

[root@instance-9a809cx7 src]# wget http://prdownloads.sourceforge.net/libpng/zlib-1.2.11.tar.gz
[root@instance-9a809cx7 src]# tar zxvf zlib-1.2.11.tar.gz
[root@instance-9a809cx7 src]# cd zlib-1.2.11
[root@instance-9a809cx7 zlib-1.2.11]# ./configure
[root@instance-9a809cx7 zlib-1.2.11]# make && make install

3.2、pcre安装
Pcre官网
下载最新版本8.42
解压、编译安装

[root@instance-9a809cx7 src]# wget  https://jaist.dl.sourceforge.net/project/pcre/pcre/8.42/pcre-8.42.tar.gz
[root@instance-9a809cx7 src]# tar zxvf pcre-8.42.tar.gz 
[root@instance-9a809cx7 src]# cd pcre-8.42/
[root@instance-9a809cx7 pcre-8.42]# ./configure 
[root@instance-9a809cx7 pcre-8.42]# make && make install
[root@instance-9a809cx7 pcre-8.42]# 

查看版本

[root@instance-9a809cx7 pcre-8.42]# pcre-config --version
8.42
[root@instance-9a809cx7 pcre-8.42]# 

3.3、OpenSSL安装
OpenSSL官网
下载并解压、安装

[root@instance-9a809cx7 src]# wget https://www.openssl.org/source/openssl-1.0.2o.tar.gz^C
[root@instance-9a809cx7 src]# tar zxvf openssl-1.0.2o.tar.gz 
[root@instance-9a809cx7 src]# cd openssl-1.0.2o/
[root@instance-9a809cx7 src]# cd openssl-1.0.2o/
[root@instance-9a809cx7 openssl-1.0.2o]# ./config 
[root@instance-9a809cx7 openssl-1.0.2o]# make && make install

4、Nginx安装(最新稳定版为1.14.0)
官网

[root@instance-9a809cx7 src]# wget http://nginx.org/download/nginx-1.14.0.tar.gz
[root@instance-9a809cx7 src]# tar zxvf nginx-1.14.0.tar.gz 
[root@instance-9a809cx7 src]# cd nginx-1.14.0/
[root@instance-9a809cx7 nginx-1.14.0]# ./configure --with-http_ssl_module --with-pcre=../pcre-8.42 --with-zlib=../zlib-1.2.11 --with-openssl=../openssl-1.0.2o
[root@instance-9a809cx7 nginx-1.14.0]# make && make install

检查Nginx的正确性：

[root@instance-9a809cx7 nginx-1.14.0]# /usr/local/nginx/sbin/nginx -t 
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@instance-9a809cx7 nginx-1.14.0]# 

启动Nginx：

[root@instance-9a809cx7nginx-1.14.0]# /usr/local/nginx/sbin/nginx

停止Nginx

/usr/local/nginx/sbin/nginx -s stop 

开机自启动

[root@instance-9a809cx7 nginx-1.14.0]# chmod 755 /etc/rc.d/rc.local
[root@instance-9a809cx7 nginx-1.14.0]# vim /etc/rc.d/rc.local
[root@instance-9a809cx7 nginx-1.14.0]# 

二、MySQL安装
1、检查是否安装mariadb如安装则卸载

[root@instance-9a809cx7 src]# yum list installed | grep mariadb 
mariadb-libs.x86_64                  1:5.5.56-2.el7                    @anaconda
[root@instance-9a809cx7 src]# yum -y remove mariadb*

2、安装Mysql
下载

[root@instance-9a809cx7 src]# wget https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm

检查MySQL yum源是否安装成功

[root@instance-9a809cx7 src]# yum repolist enabled | grep "mysql.*-community.*" 
!mysql-connectors-community/x86_64 MySQL Connectors Community                 74
!mysql-tools-community/x86_64      MySQL Tools Community                      74
!mysql80-community/x86_64          MySQL 8.0 Community Server                 49

安装

[root@instance-9a809cx7 src]# yum -y  install mysql-server
[root@instance-9a809cx7 src]# 

启动MySQL

[root@instance-9a809cx7 src]# service mysqld start 
Redirecting to /bin/systemctl start mysqld.service

查看初始密码然后登录
root@localhost: uXg%-ip2**[密码]

[root@instance-9a809cx7 src]# cat /var/log/mysqld.log|grep 'A temporary password'
2018-11-12T10:17:55.906846Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: uXg%-ip2***
[root@instance-9a809cx7 src]# mysql -uroot -p

密码可以自行修改
命令如下

mysql> alter user 'root'@'localhost' identified by 'youpassword'; 
mysql> flush privileges;

mysql> alter user 'root'@'localhost' identified by 'qA123,./';
Query OK, 0 rows affected (0.10 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

重启

systemctl restart mysqld.service

其它命令

systemctl start mysqld      #启动
systemctl stop mysqld       #停止
systemctl restart mysqld    #重启
systemctl enable mysqld     #设置开机启动
systemctl status mysqld     #查看状态

三、PHP安装
由于yum 直接安装版本是5.4，所以我们要动更新rpm

[root@instance-9a809cx7 src]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm   
[root@instance-9a809cx7 src]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

查看版本5.5~7.2都有

[root@instance-9a809cx7 src]# yum list php*

安装

[root@instance-9a809cx7 src]# yum -y install php72w-gd php72w-imap php72w-ldap php72w-odbc php72w-pear php72w-xml php72w-xmlrpc php72w-mysqlnd php72w-pdo

安装PHP-FPM
要让PHP以FastCGI的方式与nginx进行交互，需要有PHP-FPM模块的支持。

[root@instance-9a809cx7 src]# php72w-fpm.x86_64

查看版本

[root@instance-9a809cx7 src]# php-fpm -v
PHP 7.2.11 (fpm-fcgi) (built: Oct 11 2018 19:18:07)
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
[root@instance-9a809cx7 src]# 

启动PHP-FPM

[root@instance-9a809cx7 src]# systemctl start php-fpm

配置Nginx支持PHP
把65~72行注释去掉，可能会存在偏差自己看下然后修改，然后修改/scripts为$document_root

[root@instance-9a809cx7 src]# vi /usr/local/nginx/conf/nginx.conf

重启生效：

[root@instance-9a809cx7 src]# /usr/local/nginx/sbin/nginx -s reload

然后测试是否成功 :

如果有开启防火墙记得开放80端口

systemctl status firewalld   #查看状态或者netstat -nltp
firewall-cmd --reload    #重启防火墙
firewall-cmd --zone=public --add-port=80/tcp --permanent #开启80端口
