LNMP环境搭建与配置

1.安装MySQL

（1）卸载mariadb

# rpm -qa | grep mariadb               查看有无安装mariadb

# rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64                       卸载mariadb

(2)下载

将压缩包上传到/opt下

#cd /opt                                       软件包都放在这里方便管理

（3）.解压

# tar zxvf mysql-5.7.34-linux-glibc2.12-x86_64.tar.gz

(4).安装和配置

安装依赖包

# yum install ncurses-devel autoconf -y

# groupadd mysql

# useradd -g mysql -s /sbin/nologin -d /usr/local/mysql -MN mysql

# mkdir /data/mysql/data -p

# chown -R mysql:mysql /data/mysql

# mv mysql-5.7.34-linux-glibc2.12-x86_64 /usr/local/

# ln -s /usr/local/mysql-5.7.34-linux-glibc2.12-x86_64 /usr/local/mysql

# chown -R mysql.mysql /usr/local/mysql

# cd /usr/local/mysql

# >/etc/my.cnf

# cp /etc/my.cnf /etc/my.cnf.bak

# vi  /etc/my.cnf

[client]

port            = 3306

socket          = /tmp/mysql.sock

 

[mysql]

no-auto-rehash

 

[mysqld]

user = mysql

basedir = /usr/local/mysql

datadir = /data/mysql/data

port = 3306

socket = /tmp/mysql.sock

log-error = error.log

slow_query_log_file = slow.log

character-set-server = utf8

open_files_limit = 65535

max_connections = 100

max_connect_errors = 100000

lower_case_table_names =1

 

初始化mysql

# /usr/local/mysql/bin/mysqld --initialize

# grep 'temporary password' /data/mysql/data/error.log                查看MySQL密码

(5).复制启动脚本文件

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

（6）添加环境变量

echo "export PATH=/usr/local/mysql/bin:$PATH">>/etc/profile

source /etc/profile

（7）启动mysql

service mysql start 

（8）查看mysql进程

ps -ef |grep mysql

（9）登录mysql

mysql -uroot -p

输入密码（密码是root@localhost后面的）

（10）修改mysql密码

mysql> alter user user() identified by 'test';

Query OK, 0 rows affected (0.00 sec)

（11）登录mysql

  mysql -uroot -ptest

注：exit退出MySQL

2.安装Nginx

（1）# cd /etc/yum.repos.d

         #vi nginx.repo

[nginx]

name=nginx       repo

baseurl=http://nginx.org/packages/centos/7/$basearch/

gpgcheck=0

enabled=1

（2）执行yum安装

[root@nginx ~]# yum install  nginx   -y

[root@nginx ~]# systemctl start nginx

[root@nginx ~]# systemctl enable nginx

3.安装PHP

（1）使用第三方扩展epel源安装php7.2

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

（2）清除版本                                                             

yum -y remove php*

（3）安装php

yum -y install php72w php72w-cli php72w-fpm php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml php72w-redis（耐心等待，可能会加载的慢一些）

（4）启动php-fpm服务

systemctl enable php-fpm.service

systemctl start php-fpm.service

（5）启动php-fpm

service php-fpm start

4.配置nginx支持PHP

（1）  # cd /etc/nginx/conf.d

           #vi default.conf

红字是修改添加的内容

server {

    listen       80;

    server_name  localhost;

 

    #access_log  /var/log/nginx/host.access.log  main;

 

    location / {

        root   /soft/code;

        index  index.php index.html index.htm;

        location ~ \.php$ {

            fastcgi_pass    127.0.0.1:9000;

            fastcgi_index   index.php;

            fastcgi_param  SCRIPT_FILENAME  /soft/code$fastcgi_script_name;

            include  fastcgi_params;

        }

    }

 

    #error_page  404              /404.html;

 

    # redirect server error pages to the static page /50x.html

    #

    error_page   500 502 503 504  /50x.html;

    location = /50x.html {

        root   /usr/share/nginx/html;

    }

 

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80

    #

    #location ~ \.php$ {

    #    proxy_pass   http://127.0.0.1;

    #}

 

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

    #

    #location ~ \.php$ {

    #    root           html;

    #    fastcgi_pass   127.0.0.1:9000;

    #    fastcgi_index  index.php;

    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

    #    include        fastcgi_params;

    #}

 

    # deny access to .htaccess files, if Apache's document root

    # concurs with nginx's one

    #

    #location ~ /\.ht {

    #    deny  all;

    #}

}

（2） 重启nginx

          nginx -t

          nginx -s reload

（3） 新建目录

           mkdir -p /soft/code

            vi /soft/code/info.php

            <?php

             phpinfo();

             ?>

（4）浏览网页

http://192.168.60.10/info.php    （IP地址是自己设置的地址）
