第48課 LNMP服務(wù)搭建 2019-06-06

第一步;搭建LNMP環(huán)境：

1、安裝nginx服務(wù)：

1.1 先在新創(chuàng)文件nginx.repo下面寫(xiě)入nginx官網(wǎng)最新源信息：
[root@web02 ~]# cat  /etc/yum.repos.d/nginx.repo 
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
1.2 啟動(dòng)nginx服務(wù)，加入開(kāi)機(jī)自啟：
 [root@web02 ~]# systemctl start  nginx
[root@web02 ~]# systemctl enable  nginx
[root@web02 ~]# systemctl status  nginx
● nginx.service - nginx - high performance web server
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
   Active: active (running) since Tue 2019-06-11 15:53:23 CST; 12min ago
     Docs: http://nginx.org/en/docs/
 Main PID: 7232 (nginx)
   CGroup: /system.slice/nginx.service
           ├─7232 nginx: master process /usr/sbin/nginx -c /et...
           └─7233 nginx: worker process

Hint: Some lines were ellipsized, use -l to show in full.

2、 安裝mysql數(shù)據(jù)庫(kù)服務(wù)：

2.1 安裝mysql：
[root@web02 ~]# yum install -y mariadb-server 
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.huaweicloud.com
 * extras: mirrors.nwsuaf.edu.cn
 * updates: mirrors.163.com
 * webtatic: us-east.repo.webtatic.com
Package 1:mariadb-server-5.5.60-1.el7_5.x86_64 already installed and latest version
Nothing to do
2.2 啟動(dòng)mysql服務(wù)，加入開(kāi)機(jī)自啟：
[root@web02 ~]# systemctl start mariadb.service 
[root@web02 ~]# systemctl enable mariadb.service 
[root@web02 ~]# systemctl status mariadb.service 
● mariadb.service - MariaDB database server
   Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled)
   Active: active (running) since Tue 2019-06-11 15:53:28 CST; 23min ago
 Main PID: 7289 (mysqld_safe)
   CGroup: /system.slice/mariadb.service
           ├─7289 /bin/sh /usr/bin/mysqld_safe --basedir=/usr

3、安裝php服務(wù)2種方法：

3.1 網(wǎng)絡(luò)好的情況下：
1、rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
2、rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
3、yum -y install php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb
3.2 網(wǎng)絡(luò)不好的情況下，需要用rpm包安裝：
1、命令：rpm -ivh  ‘壓縮包文件’
2、yum -y install php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb

4、創(chuàng)建數(shù)據(jù)庫(kù)：

4.1 檢查數(shù)據(jù)庫(kù)和用戶
[root@web02 ~]# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 3
Server version: 5.5.60-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
'//查看所有數(shù)據(jù)庫(kù)'
MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+
4 rows in set (0.04 sec)
'//查看mysql數(shù)據(jù)庫(kù)中的user表中的user列和host列（用戶）'
MariaDB [(none)]> select user,host  from mysql.user;
+------+-----------+
| user | host      |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1       |
|      | localhost |
| root | localhost |
|      | web02     |
| root | web02     |
+------+-----------+
6 rows in set (0.00 sec)
4.2 創(chuàng)建數(shù)據(jù)庫(kù)和創(chuàng)建用戶：
MariaDB [(none)]> create database wordpress;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> grant all on wordpress.*   to 'wordpress'@'172.16.1.%'  identified  by '123456';
Query OK, 0 rows affected (0.03 sec)

MariaDB [(none)]> grant all on wordpress.*   to 'wordpress'@'localhost'  identified  by '123456';
Query OK, 0 rows affected (0.00 sec)
4.4 檢查創(chuàng)建的用戶是否生效：
[root@web02 ~]# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 8
Server version: 5.5.60-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> select user,host  from mysql.user;
+-----------+------------+
| user      | host       |
+-----------+------------+
| root      | 127.0.0.1  |
| wordpress | 172.16.1.% |
| root      | ::1        |
|           | localhost  |
| root      | localhost  |
| wordpress | localhost  |
|           | web02      |
| root      | web02      |
+-----------+------------+
8 rows in set (0.00 sec)

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| wordpress          |
+--------------------+
5 rows in set (0.00 sec)
4.5 查看是否可以登錄到數(shù)據(jù)庫(kù)：
[root@web02 ~]# mysql -uwordpress -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 10
Server version: 5.5.60-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> 
可以登陸進(jìn)去新創(chuàng)建的wordpress數(shù)據(jù)庫(kù)。

5、php服務(wù)配置：

5.1 修改php文件信息：
[root@web02 ~]# egrep '^user|^group' /etc/php-fpm.d/www.conf 
user = nginx
group = nginx
5.2 修改完文件信息后，需要重啟php服務(wù)：
[root@web02 ~]# systemctl restart php-fpm.service 
[root@web02 ~]# ss -lntup|grep 9000
tcp    LISTEN     0      128    127.0.0.1:9000                  *:*                   users:(("php-fpm",pid=8216,fd=9),("php-fpm",pid=8215,fd=9),("php-fpm",pid=8214,fd=9),("php-fpm",pid=8213,fd=9),("php-fpm",pid=8212,fd=9),("php-fpm",pid=8210,fd=7))
[root@web02 ~]# ps -ef |grep php
root       8210      1  0 17:08 ?        00:00:00 php-fpm: master process (/etc/php-fpm.conf)
nginx      8212   8210  0 17:08 ?        00:00:00 php-fpm: pool www
nginx      8213   8210  0 17:08 ?        00:00:00 php-fpm: pool www
nginx      8214   8210  0 17:08 ?        00:00:00 php-fpm: pool www
nginx      8215   8210  0 17:08 ?        00:00:00 php-fpm: pool www
nginx      8216   8210  0 17:08 ?        00:00:00 php-fpm: pool www
root       8239   7777  0 17:09 pts/0    00:00:00 grep --color=auto php

第二步：檢測(cè)環(huán)境：

1、檢查nginx服務(wù)和php服務(wù)是否正常：

1.1 conf.d下面的主配置文件：
[root@web01-13 /etc/nginx/conf.d]# cat  02-blog.conf.bak 
server   {
    listen       80;
    server_name  blog.oldboy.com;
    access_log  /var/log/nginx/access_blog.log  main;
    root   /usr/share/nginx/html/blog;
    location / {
    index  index.php index.html index.htm;
    }
   location ~* \.(php|php5)$ {
       fastcgi_pass   127.0.0.1:9000;
       fastcgi_index  index.php;
       fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
       include        fastcgi_params;
   }

}
1.2 在站點(diǎn)目錄/usr/share/nginx/html/blog下面創(chuàng)建info.php文件：
[root@web02 ~]# cat /usr/share/nginx/html/blog/info.php 
<?php
        phpinfo();
?>

1.3 進(jìn)入瀏覽器檢測(cè)：

php網(wǎng)頁(yè)驗(yàn)證.png

出現(xiàn)以上圖示就表明驗(yàn)證成功。

2、檢查php服務(wù)和mysql服務(wù)是否正常：

2.1 站點(diǎn)目錄下創(chuàng)建mysqli.php文件：
[root@nginx /usr/share/nginx/html/blog]# cat  mysqli.php
<?php
$servername = "localhost";
$username = "wordpress";
$password = "123456";

// 創(chuàng)建連接
$conn = mysqli_connect($servername, $username, $password);

// 檢測(cè)連接
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
echo "php連接MySQL數(shù)據(jù)庫(kù)成功";
?>

2.2 進(jìn)入瀏覽器檢測(cè)：

mysql檢測(cè).png

出現(xiàn)上圖證明php服務(wù)和mysql服務(wù)已經(jīng)連接成功。
第三步：搭建博客網(wǎng)站：

3.1 代碼上線具體步驟：

[root@web02 ~]# tar xf wordpress-5.2.1.tar.gz 
[root@web02 ~]# ll
total 10980
drwxr-xr-x  5 nobody 65534     4096 May 22 02:24 wordpress
-rw-r--r--  1 root   root  11199196 Jun  8 08:48 wordpress-5.2.1.tar.gz

[root@web02 ~] mv wordpress/*  /usr/share/nginx/html/blog/
[root@web02 ~] chown -R nginx.nginx /usr/share/nginx/html/blog/

[root@web02 ~]# ll -d  nginx.nginx /usr/share/nginx/html/blog/ 
ls: cannot access nginx.nginx: No such file or directory
drwxr-xr-x 5 nginx nginx 4096 Jun 11 17:37 /usr/share/nginx/html/blog/

3.2 瀏覽器直接輸入IP地址，進(jìn)行博客創(chuàng)建即可：

mysql數(shù)據(jù)庫(kù).png

證明博客搭建成功。
