LNMP全yum部署安裝和集群架構(gòu)遷移
1)yum安裝NGINX
[root@web02 ~]# cat /etc/yum.repos.d/nginx.repo #<==配置Nginx官方y(tǒng)um源秋麸。
[nginx]
name=Nginx repo by oldboy
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
說明:如果是用epel源安裝需要提前配置epel源,本書安裝系統(tǒng)時已經(jīng)配置過了epel源了。
[root@web02 ~]# rpm -qa nginx ?????????????#<==提前檢查玻褪,發(fā)現(xiàn)沒有蛉顽。
[root@web02 ~]# yum install nginx -y ??????#<==開始yum安裝nginx。
[root@web02 ~]# rpm -qa nginx
nginx-1.16.0-1.el7.ngx.x86_64 ?????????????#<==安裝完畢后檢查,發(fā)現(xiàn)有了咪橙。
[root@web02 ~]# systemctl start nginx ?????#<==啟動Nginx服務(wù)聂宾。果善。
[root@web02 ~]# systemctl enable nginx ????#<==設(shè)置開機自啟動。
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@web02 ~]# systemctl status nginx ????#<==查看狀態(tài)系谐。
● nginx.service - nginx - high performance web server
???Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
Active: active (running) since六 2019-05-04 11:04:21 CST; 9s ago
[root@web02 ~]# netstat -lntup|grep nginx ?#<==檢查端口巾陕。

?
2) yum安裝PHP
第一個:解決PHP軟件沖突
yum remove php-mysql php php-fpm php-common
第二個:更新yum源信息梯刚,用戶安裝php程序
?
#準備yum安裝軟件擴展源信息
wget -q https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
wget -q https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
?
rpm -Uvh epel-release-latest-7.noarch.rpm
rpm -Uvh webtatic-release.rpm
第三個:直接安裝php服務(wù)相關(guān)軟件
yum install php71w php71w-cli php71w-common php71w-devel php71w-embedded ??-y
yum install php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml ?-y
yum install php71w-fpm php71w-mysqlnd php71w-opcache ?php71w-pecl-memcached ?-y
yum install php71w-pecl-redis php71w-pecl-mongodb -y
###############檢查是否安裝成功###############
rpm -qa mod_php71w php71w-cli php71w-common php71w-devel php71w-embedded
rpm -qa php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml
rpm -qa php71w-fpm php71w-mysqlnd php71w-opcache
rpm -qa php71w-pecl-redis php71w-pecl-mongodb php71w-pecl-memcached
?
啟動
php-fpm -t
systemctl start php-fpm
systemctl enable php-fpm
?
============================================

php71w-gd ?????---和顯示圖形相關(guān)的軟件
php71w-mcrypt ?---和數(shù)據(jù)傳輸加密相關(guān)
php71w-pdo ????---讓php和數(shù)據(jù)庫建立聯(lián)系
php71w-fpm ????---
==========================================
[root@web01 /]# rpm -ql mod_php71w
/etc/httpd/conf.d/php.conf ???????????---
/etc/httpd/conf.modules.d/10-php.conf
/usr/lib64/httpd/modules/libphp7-zts.so
/usr/lib64/httpd/modules/libphp7.so
/usr/share/httpd/icons/php.gif
/var/lib/php/session
/var/lib/php/wsdlcache
===========================
[root@web01 /]# rpm -ql php71w-fpm
/etc/logrotate.d/php-fpm
/etc/php-fpm.conf ????????--- PHP FPM配置
/etc/php-fpm.d
/etc/php-fpm.d/www.conf ??--- PHP FPM子目錄配置
/etc/sysconfig/php-fpm
/usr/lib/systemd/system/php-fpm.service
/usr/lib/tmpfiles.d/php-fpm.conf
/usr/sbin/php-fpm ????????--- PHP FPM啟動命令
?
?
重要文件和目錄信息
/etc/php-fpm.conf ???---php-fpm進程的配置文件
/etc/php-fpm.d ??????---php-fpm進程加載配置文件的目錄
/etc/php-fpm.d/www.conf
user = nginx ???????---利用指定用戶管理php工作進程 ???建議配置和nginx服務(wù)相同的用戶
group = nginx ??????---利用指定用戶組管理php工作進程
listen = 127.0.0.1:9000 ??---指定php服務(wù)運行后凉馆, 監(jiān)聽的地址和端口信息
listen.allowed_clients = 127.0.0.1 ??---只允許本地訪問php 9000端口服務(wù)
?
3) yum安裝mariadb數(shù)據(jù)庫(mysql同源)
yum install mariadb mariadb-server -y
systemctl start mariadb.service
systemctl enable mariadb.service
?
4)驗證MariaDB安裝
[root@web01 ~]# mysql
Welcome to the MariaDB monitor. ?Commands end with ; or \g.
Your MariaDB connection id is 2
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)]> ?#<==成功標識。
?
?
?
5)配置測試PHP
a.調(diào)整轉(zhuǎn)發(fā)PHP請求
[root@web01 /etc/nginx/conf.d]# cat blog.conf
server {
????????listen ??????80;
????????server_name ?blog.etiantian.org;
????????location / {
????root ??/usr/share/nginx/html/blog;
????????????index ?index.php;
?
location ~ .*\.(php|php5)?$ {
????????root ??/usr/share/nginx/html/blog;
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
????????}
????}
nginx -t
systemctl reload nginx
netstat -lntup|grep nginx
?
?
測試:
echo "<?php phpinfo(); ?>" > /usr/share/nginx/html/test_info.php
php /usr/share/nginx/html/test_info.php
瀏覽器打開亡资。
?
10.0.0.7/test_info.php
?
6)配置測試mysql
[root@web01 /usr/share/nginx/html]# 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.
?
MariaDB [(none)]> create database wordpress;
Query OK, 1 row affected (0.00 sec)
?
MariaDB [(none)]> grant all on wordpress.* to wordpress@'localhost' identified by 'oldboy123';
Query OK, 0 rows affected (0.05 sec)
?
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
?
MariaDB [(none)]> quit
Bye
[root@web01 /usr/share/nginx/html]# cat test_mysql.php
<?php
$link_id=mysqli_connect('localhost','wordpress','oldboy123') or mysql_error();
if($link_id){
echo "mysql successful by oldboy.\n";
}else{
echo mysql_error();
}
?>
[root@web01 /usr/share/nginx/html]# php test_mysql.php
mysql successful by oldboy.
?
?
?
集群調(diào)整:
1)web02 blog數(shù)據(jù)遷移至web01
scp -rp 172.16.1.8:/application/nginx/html/blog /usr/share/nginx/html
2)配置調(diào)整澜共,偽靜態(tài),路徑加blog
[root@web01 /etc/nginx/conf.d]# cat blog.conf
server {
????????listen ??????80;
????????server_name ?blog.etiantian.org;
????????location / {
????root ??/usr/share/nginx/html/blog; ###################
????????????index ?index.php;
????????}
if (-f $request_filename/index.html){
????rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
????????????rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
????rewrite (.*) /index.php;
}
????????location ~ .*\.(php|php5)?$ {
????????root ??/usr/share/nginx/html/blog;
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
????????}
????}
3)共享存儲調(diào)整
yum install rpcbind nfs-utils -y
systemctl start rpcbind
systemctl enable rpcbind
?
mount -t nfs 172.16.1.31:/data/blog_nfs ?/usr/share/nginx/html/blog/wp-content/uploads
ls /usr/share/nginx/html/blog/wp-content/uploads
別忘了锥腻,開機自動掛載嗦董。
