nginx編譯安裝步驟
①. 檢查軟件安裝的系統環境
cat /etc/redhat-release
uname -r
②. 安裝nginx的依賴包(pcre-devel openssl-devel)---假設不進行安裝
yum install -y pcre-devel openssl-devel
③. 下載nginx軟件---1.10.2 復制鏈接地址(統一位置進行下載)
mkdir -p /home/oldboy/tools
cd /home/oldboy/tools
wget -q http://nginx.org/download/nginx-1.10.3.tar.gz
說明:軟件很小,用心查看一下
④. 編譯安裝軟件步驟
a. 解壓要編譯安裝的軟件(解壓軟件---配置(./configure)---做菜(編譯 make)---上菜(安裝 make install))
tar xf nginx-1.10.2.tar.gz
ps -ef |grep sshd
id www #查看用戶
uid=666(www) gid=666(www) groups=666(www)
userdel -r www #刪除虛擬用戶
useradd www -s /sbin.nologin -M #創建虛擬用戶
id www
cd nginx-1.10.2
ls (裏面的內容就是源代碼(config readme安裝說明)---默認編譯會安裝到/usr/local目錄)
useradd -s /sbin/nologin -M www <--- 創建web服務程序www用戶
./configure --prefix=/application/nginx-1.10.2 --user=www --group=www --with-http_stub_status_module --with-http_ssl_module #配置文件
echo $?
(編譯參數說明後續補充說明)
make 編譯
echo $?
make install 編譯安裝
軟件編譯過程中,利用返回值,判斷操作是否正確
echo $?
cd /application/
ln -s /application/nginx-1.10.2 /application/nginx <--- 安裝完成一個軟件要做一個軟鏈接
b. 啟動nginx軟件程序進行測試
/application/nginx/sbin/nginx
lsof -i:80
netstat -lntup|grep 80 查看80端口
瀏覽器訪問 10.0.0.8:80
至此軟件安裝完畢:

mysql軟件
mysql軟件下載地址信息: www.mysql.com mirrors.sohu.com
mysql軟件下載完畢後,查看mysql解壓後目錄文件大小
講解安裝mysql步驟
1) 下載解壓mysql二進制軟件包
tar xf mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz
#解壓數據庫壓縮包
2) 添加mysql程序運行時的管理用戶
useradd -s /sbin/nologin -M mysql
#創建虛擬用戶
3) 將mysql解壓後的程序包搬家到程序目錄下,並進行重命名
mkdir -p /application/
#創建程序目錄
mv /server/tools/mysql-5.6.34-*-x86_64 /application/mysql-5.6.34
#將程序搬遷
4) 為mysql服務程序創建軟鏈接
ln -s /application/mysql-5.6.34/ /application/mysql
#創建軟連接
5) 讓mysql用戶管理 /application/mysql/
chown -R mysql.mysql /application/mysql/data
## 用虛擬用戶管理
6) 初始化數據庫
#1. 確認軟件安裝在哪裏
#2. 確認數據存放在哪裏
#3. 確認MySQL使用的用戶誰?
/application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data --user=mysql
==================================================================================================
下面是解釋
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
mysql啟動腳本 默認放在support-files/mysql.server
記得給MySQL設置個密碼
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
創建密碼的代碼
/application/mysql/bin/mysqladmin -u root password ‘new-password‘
遠程創建密碼
/application/mysql/bin/mysqladmin -u root -h web01 password ‘new-password‘
==================================================================================================
7) 復制啟動腳本 授權
cp /application/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
8) 修改啟動腳本 和 mysql命令中的路徑
sed -i ‘s#/usr/local/mysql#/application/mysql#g‘ /application/mysql/bin/mysqld_safe /etc/init.d/mysqld
#將默認的東西改為自己的 將後面兩個配置文件的全部都`修改
9) 復制默認的配置文件
\cp /application/mysql/support-files/my-default.cnf /etc/my.cnf #復制
/etc/init.d/mysqld start #啟動
至此,mysql數據庫安裝與啟動完成;可以檢測進程和服務端口,確認mysql服務是否啟動正確
講解管理mysql數據庫
1) 進入與退出mysql數據庫方法:
/application/mysql/bin/mysql
=============================================
擴展知識:登錄數據庫命令簡化方法
echo ‘export PATH=/application/mysql/bin:$PATH‘ >>/etc/profile
source /etc/profile
which mysql
=============================================
退出數據庫時,盡量不要用ctrl+c進行退出mysql 用ctrl+d進行退出
2) 設置mysql服務開機自啟動
####11.加入開機自啟動
chkconfig --add mysqld
chkconfig mysqld on
3) 設置mysql數據庫登錄用戶名與密碼
####12.給MySQL root用戶設置密碼
/application/mysql/bin/mysqladmin -u root password ‘oldboy123‘
mysql -u root -p oldboy123
初級 添加刪除系列
#創建數據庫

02:LNMP PHP軟件安裝
講解安裝PHP步驟
1) 解決PHP軟件的依賴關系
yum install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel -y
yum install freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libxslt-devel -y
rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
#查看是否下載成功
libiconv軟件安裝--和字符集轉換相關的軟件
#mkdir -p /server/tools
cd /server/tools
#wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar zxf libiconv-1.14.tar.gz
cd libiconv-1.14
./configure --prefix=/usr/local/libiconv
make
make install
cd ../
和數據加密相關的三個軟件安裝
#wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
#更換源
yum -y install libmcrypt-devel mhash mcrypt
#查看是否安裝成功
rpm -qa libmcrypt-devel mhash mcrypt
2) 下載解壓PHP軟件
cd /server/tools/ #進入目錄
tar xf php-5.5.32.tar.gz #解壓壓縮包
cd php-5.5.32 #進入目錄
#下面是配置文件
./configure \
--prefix=/application/php-5.5.32 \

make
make install <- 創建目錄,生成程序文件信息
了解FastCGI
3) PHP軟件程序創建軟鏈接
ln -s /application/php-5.5.32/ /application/php
4) 配置php解析文件/配置php-fpm配置文件
#上邊是開發用的 下面是運維用的
cd /server/tools/php-5.5.32
cp php.ini-production /application/php/lib/php.ini
php.ini-production 與 php.ini-development 文件區別關系對比
擴展:文件比較命令 diff zdiff vimdiff windows上的文件比較
cd /application/php/etc/
cp php-fpm.conf.default php-fpm.conf
5) 啟動php-fpm程序
/application/php/sbin/php-fpm
)6檢查
lsof -i :9000 <--- 確認php 9000端口是否正確啟動
ps -ef|grep php-fpm
03:wordpress博客站點部署配置
1) 修改nginx配置文件,使nginx程序與php程序建立聯系
vim extra/blog.conf
server {
listen 80;
server_name blog.etiantian.org;
location / {
root html/blog;
index index.php index.html index.htm; <-- 需要註意編輯修改默認首頁文件 index
}
location ~* .*\.(php|php5)?$ { #主要添加下面這行
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
說明:利用nginx的location區塊實現動態請求與靜態請求的分別處理
實例
[[email protected] extra]# pwd
/application/nginx/conf/extra
[[email protected] extra]# cat blog.conf
server {
listen 80;
server_name blog.etiantian.org;
location / {
root html/blog;
index index.php index.html index.htm;
}
location ~* .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
2) 編輯nginx與php連通性測試文件,並進行測試
echo ‘<?php phpinfo(); ?>‘ >/application/nginx/html/blog/test_info.php #創建測試文件
測試站點
curl http://blog.etiantian.org/index.html <-- 靜態請求站點文件信息測試
curl http://blog.etiantian.org/test_info.php <-- 動態請求站點文件信息測試
說明:當php服務停止時,9000端口信息消失,即停止PHP錯誤報502錯誤
linux系統測試完畢後,建議利用瀏覽器進行最終測試,測試效果更明顯些
3) 編輯php與mysql連通性測試文件,並進行測試
a. 創建數據庫
mysql -u root -p oldboy123; #進入數據庫
show databases; <--- 查看當前數據庫信息
create database wordpress;
實例
mysql> mysql -uroot -poldboy123;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘mysql -uroot -poldboy123‘ at line 1
mysql> create database wordpress;
Query OK, 1 row affected (0.53 sec)
b. 添加用戶信息
grant all on wordpress.* to ‘wordpress‘@‘localhost‘ indentified by ‘oldboy123‘;
grant all on wordpress.* to ‘wordpress‘@‘172.16.1.%‘ indentified by ‘oldboy123‘;
flush privileges;
drop user [email protected]‘172.16.1.8‘; <--- 刪除用戶信息
select user,host from mysql.user; <--- 查看用戶信息
mysql -uwordpress -p123456 <--- 測試創建的用戶連接
show databases; <--- 查看當前數據庫信息
實例
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
| wordpress |
+--------------------+
5 rows in set (0.33 sec)
mysql> grant all on wordpress.* to ‘wordpress‘@‘10.0.0.%‘ identified by ‘oldboy123‘;
Query OK, 0 rows affected (0.47 sec)
mysql> select user,host from mysql.user;
+-----------+-----------+
| user | host |
+-----------+-----------+
| wordpress | 10.0.0.% |
| root | 127.0.0.1 |
| root | ::1 |
| | localhost |
| root | localhost |
| | web01 |
| root | web01 |
+-----------+-----------+
7 rows in set (0.00 sec)
c. 測試php與數據庫連通性
vim test_mysql.php
<?php
//$link_id=mysql_connect(‘主機名‘,‘用戶‘,‘密碼‘);
//mysql -u用戶 -p密碼 -h 主機
$link_id=mysql_connect(‘localhost‘,‘wordpress‘,‘oldboy123‘) or mysql_error();
if($link_id){
echo "mysql successful by oldboy !\n";
}else{
echo mysql_error();
}
?>
curl blog.etiantian.org/test_mysql.php <-- 測試php與數據庫的連通性
4) 下載部署wordpress博客程序(https://cn.wordpress.org/ 英文官網:https://www.wordpress.org/ )
wget https://cn.wordpress.org/wordpress-4.5.1-zh_CN.tar.gz
tar xf wordpress-4.5.1-zh_CN.tar.gz
mv wordpress/* /application/nginx/html/blog/
chown -R www.www /application/nginx/html/blog/
註意:確認hosts文件進行了解析
瀏覽器頁面進行wordpress部署
vim wp-config.php 可以修改wordpress上的數據庫連接參數信息
04:wordpress博客站點數據庫遷移
遷移數據庫:利用數據庫備份命令
1) 備份數據庫數據庫信息
mysqldump -uroot -poldboy123 --all-databases >/tmp/bak.sql
ll /tmp/bak.sql -h
scp /tmp/bak.sql 172.16.1.51:/tmp/
2) 恢復數據庫數據庫信息
##db01
mysql -uroot -poldboy123 </tmp/bak.sql
###db01添加新的用戶
grant all on wordpress.* to [email protected]‘172.16.1.0/255.255.255.0‘ identified by ‘oldboy123‘;
flush privileges;
mysql -uwordpress -poldboy123 -h 172.16.1.51
3) 數據庫遷移完畢,修改網站連接數據庫的配置文件
mysql -uwordpress -poldboy123 -h 172.16.1.51 <-- 修改配置文件之前,先測試網站web服務器與遷移後的數據庫連通性
vim wp-config.php <-- 修改wordpress上的數據庫連接參數信息
/** MySQL主機 */
define(‘DB_HOST‘,‘172.16.1.51‘) <-- 修改連接的主機信息,將localhost修改為172.16.1.51
說明:web服務器數據庫此時可以關閉了
05. 進行數據遷移到NFS共享服務器
01:先將原有目錄中數據移出
cd /application/nginx/html/blog/wp-content/uploads
mkdir /tmp/wordpress_backup -p
mv ./* /tmp/wordpress_backup/
02:NFS服務器上配置創建共享目錄
vim /etc/exports
/data 172.16.1.0/24(rw,sync,all_squash)
showmount -e 172.16.1.31
mount -t nfs 172.16.1.31:/data /mnt/
showmount -e 172.16.1.31
mount -t nfs 172.16.1.31:/data/ ./uploads/
mv /tmp/wordpress_backup/* ./
