這裏是給創業公司進行更換系統。因爲平時用到的並很少，只有一臺服務器。javascript

在遷移以前把應用，數據庫數據都下載下來，而後更換系統爲centos7php

一、首先是遷移數據庫。

安裝mysql5.7數據庫後，把數據導入進數據庫。因爲linux數據嚴格區分大小寫，顧 css

#vim /etc/my.cnf

添加lower_case_table_names=1 到my.cnf中。html

1.二、安裝tomcat，將應用放到tomcat中。

2.Nginx安裝

我使用的環境是64位 Ubuntu 14.04。nginx依賴如下模塊：java

l gzip模塊須要 zlib 庫node

l rewrite模塊須要 pcre 庫mysql

l ssl 功能須要openssl庫linux

2.1.安裝pcre

1. 獲取pcre編譯安裝包，在http://www.pcre.org/上能夠獲取當前最新的版本nginx

2. 解壓縮pcre-xx.tar.gz包。c++

3. 進入解壓縮目錄，執行./configure。

4. make & make install

1.2.安裝openssl

1. 獲取openssl編譯安裝包，在http://www.openssl.org/source/上能夠獲取當前最新的版本。

2. 解壓縮openssl-xx.tar.gz包。

3. 進入解壓縮目錄，執行./config。

4. make & make install

2.3.安裝zlib

1. 獲取zlib編譯安裝包，在http://www.zlib.net/上能夠獲取當前最新的版本。

2. 解壓縮openssl-xx.tar.gz包。

3. 進入解壓縮目錄，執行./configure。

4. make & make install

2.4.安裝nginx

1. 獲取nginx，在http://nginx.org/en/download.html上能夠獲取當前最新的版本。

2. 解壓縮nginx-xx.tar.gz包。

3. 進入解壓縮目錄，執行./configure

4. make & make install

若安裝時找不到上述依賴模塊，使用--with-openssl=<openssl_dir>、--with-pcre=<pcre_dir>、--with-zlib=<zlib_dir>指定依賴的模塊目錄。如已安裝過，此處的路徑爲安裝目錄；若未安裝，則此路徑爲編譯安裝包路徑，nginx將執行模塊的默認編譯安裝。

啓動nginx以後，瀏覽器中輸入http://localhost能夠驗證是否安裝啓動成功。

五、nginx的編譯安裝後的目錄在

/usr/local/nginx/

三、nginx整合tomcat

 #vim /usr/local/nginx/conf/nginx.conf

添加圖片緩存

server_names_hash_bucket_size 128;
    client_header_buffer_size 32k;
    large_client_header_buffers 4 32k;
    client_max_body_size 50m;
    sendfile on;

    tcp_nopush on;
    tcp_nodelay on;
    fastcgi_connect_timeout 300;
    fastcgi_send_timeout 300;
    fastcgi_read_timeout 300;
    fastcgi_buffer_size 64k;
    fastcgi_buffers 4 64k;
    fastcgi_busy_buffers_size 128k;
    fastcgi_temp_file_write_size 256k;
    client_body_buffer_size 512k;

    proxy_connect_timeout 5;
    proxy_read_timeout 60;
    proxy_send_timeout 5;
    proxy_buffer_size 16k;
    proxy_buffers 4 64k;
    proxy_busy_buffers_size 128k;
    proxy_temp_file_write_size 128k;
    proxy_temp_path /yundata/temp/images;
    proxy_cache_path /yundata/cache/images levels=1:2 keys_zone=content:20m inactive=1d max_size=100m;

    gzip on;
    gzip_min_length  1k;
    gzip_buffers     4 16k;
    gzip_http_version 1.0;
    gzip_comp_level 2;
    gzip_types       text/plain application/x-javascript text/css application/xml;
    gzip_vary on;
    gzip_proxied        expired no-cache no-store private auth;
    gzip_disable        "MSIE [1-6]\.";

配置tomcat，其中應用的端口爲8080

#代理tomcat應用
server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

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


         location ~ .*＼.(gif|jpg|jpeg|png|bmp|swf)$
         {
           expires       15d;
         }

         location ~ .*＼.(js|css)?$
          {
             expires       1d;
           }
         
        location / {
            root   html;
            index  index.html index.htm;
            proxy_pass  http://www.5ayzb.com:8080;
	 }


  
#代理php應用
server {

測試配置是否有問題經過下面命令

#/usr/local/nginx/sbin/nginx -t

看是否有錯誤信息。

輸入 netstat -tpnl 檢查下是否有服務正常

[root@localhost ~]# netstat -tpnl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

[root@localhost ~]#

四、安裝php5.6

安裝依賴

# yum install gcc gcc-c++ libxml2 libxml2-devel libjpeg-devel libpng-devel freetype-devel openssl-devel libcurl-devel libmcrypt-devel

#/configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --enable-pcntl --enable-mysqlnd --enable-opcache --enable-sockets --enable-sysvmsg --enable-sysvsem  --enable-sysvshm --enable-shmop --enable-zip --enable-ftp --enable-soap --enable-xml --enable-mbstring --disable-rpath --disable-debug --disable-fileinfo --with-mysql --with-mysqli --with-pdo-mysql --with-pcre-regex --with-iconv --with-zlib --with-mcrypt --with-gd --with-openssl --with-mhash --with-xmlrpc --with-curl --with-imap-ssl

#make
。。。。。省略

#make intstall
[root@localhost php-5.6.26]# make install

配置php

# cp php.ini-production  /usr/local/php/etc/php.ini

# cp /usr/local/php/etc/php-fpm.conf.default php-fpm.conf

[root@localhost etc]# /usr/local/php/sbin/php-fpm -t
[17-Sep-2016 22:47:27] NOTICE: configuration file /usr/local/php/etc/php-fpm.conf test is successful

添加到

#cp /server/php-5.6.26/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

/server/php-5.6.26 這個是個人php的tar.xz 解壓的安裝包

添加到開機自啓

#chkconfig --add php-fpm

啓動PHP

#/etc/init.d/php-fpm start

5 nginx+php整合

5.一、修改php配置

#cd /usr/local/php/etc/
# vi php-fpm.conf

啓用以下幾行，即去掉前面的分號(;)
pid = run/php-fpm.pid
error_log = log/php-fpm.log
log_level = notice
listen = 127.0.0.1:9000
listen.allowed_clients = 127.0.0.1
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

5.二、修改nginx

[root@localhost etc]# cd /usr/local/nginx/
[root@localhost nginx]# vim conf/nginx.conf

server
           {
                   listen       80;
                   server_name bbs.5ayzb.com  #二級域名(好比mial.baidu.com)
                   server_name  ip;
                   index index.php index.html index.htm default.html default.htm default.php;
                  root  /home/website/;#php應用的文件夾
                   location ~ \.php$ {
                          root  /home/website;#php應用的文件夾
                          fastcgi_pass 127.0.0.1:9000;
                          fastcgi_index index.php;
                          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                           include fastcgi_params;
                         }

                  location /status {
                          stub_status on;
                          access_log   off;
                  }

                  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
                          {
                                  expires      30d;
                          }
                  location ~ .*\.(js|css)?$
                          {
                                  expires      12h;
                          }

                  access_log off;
          }
