一次lnmp环境升级记录

Linux , , , , 评论

集团内部要对所有服务器进行版本升级，因此代码要迁移，环境要搭建

环境变化

现役环境：

服务器版本 PHP Nginx Apache
centos 6.8 php5.6 nginx/1.12.0 Apache/2.2.15 (Unix)

升级后环境：

服务器版本 PHP Nginx Apache
centos 7.4 php5.6 nginx/1.15.10 Apache/2.4.6 (CentOS)

安装记录

1. 安装nginx

1.检查并安装Nginx基础依赖包pcre-devel openssl-devel
名称中带有”devel”字符串的软件包是必须要安装的

1

[appuser@xxxxx ~]# rpm -qa openssl-devel openssl
openssl-1.0.2k-8.el7.x86_64
[appuser@xxxxx ~]# rpm -qa pcre-devel pcre
pcre-8.32-17.el7.x86_64

2.安装pcre-devel以及openssl-devel

1
# yum install -y openssl-devel pcre-devel

安装后查看下

[appuser@xxxxx~]# rpm -qa openssl-devel openssl
openssl-1.0.2k-8.el7.x86_64
openssl-devel-1.0.2k-8.el7.x86_64
[appuser@xxxxx~]# rpm -qa pcre-devel pcre
pcre-devel-8.32-17.el7.x86_64
pcre-8.32-17.el7.x86_64

3.开始安装Nginx：

1
# mkdir /usr/local/nginx

进入目录

1
# cd /usr/local/nginx

下载软件包，进入http://nginx.org/download/复制对应版本的下载链接地址。 

1
# wget http://nginx.org/download/nginx-1.15.10.tar.gz

解压安装

[appuser@xxxxx nginx]# ls -l nginx-1.15.10.tar.gz
-rw-r--r-- 1 root root 981687 Oct 17 21:20 nginx-1.15.10.tar.gz
[appuser@xxxxx nginx]# useradd -M -s /sbin/nologin nginx 
[appuser@xxxxx nginx]# tar zxf nginx-1.15.10.tar.gz  
[appuser@xxxxx nginx]# cd nginx-1.15.10/

安装

# ./configure --prefix=/usr/local/nginx --with-http_dav_module --with-http_stub_status_module  --with-http_addition_module --with-http_sub_module  --with-http_flv_module --with-http_mp4_module --with-pcre --with-http_ssl_module --with-http_gzip_static_module  --user=nginx  --group=nginx
# make && make install

安装完成后的优化：

1
# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

启动Nginx

1
# nginx

查看

2
# netstat -anput | grep nginx
# ps -ef | grep nginx

停止

nginx -s stop   # 关闭
nginx -s quit   # 退出（也是关闭）
nginx -s reload   # 重新加载配置文件
nginx -s reopen   # 重新打开日志文件
nginx -t          # 测试配置文件
2. 安装php，php-fpm
yum安装php5.6
1
# yum install --enablerepo=remi --enablerepo=remi-php56 php php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-phpunit-PHPUnit php-pecl-xdebug php-pecl-xhprof -y

查看php版本

# php --version

[appuser@xxxx /]$ php -v
PHP 5.6.0 (cli) (built: Apr  9 2019 16:00:50)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2014 Zend Technologies

测试php-fpm

1
# netstat -lnt | grep 9000
安装php扩展

pgsql 扩展

找到相应的版本 php 5.6.0 https://www.php.net/releases/

1、从php官网下载一个合适版本的php;
2、从PHP解压包里ext目录找到pdo_pgsql 和 pgsql目录，并且复制放到liunx的 /root 目录（随便一个）
3、分别进入pdo_pgsql 和 pgsql目录 ：
phpize
./configure (./configure –with-php-config=/usr/local/php56/bin/php-config)
make

make install

Ps：这里不要直接make && make install，可能会报错，很抓狂

4、修改php配置文件php.ini，添加pgsql.so、pdo_pgsql.so模块。
extension=pgsql.so

5、重启php-fpm

pdo_pgsql 扩展
按照相同的办法，安装 pdo_pgsql
还有php配置文件php.ini添加

1
extension=pdo_pgsql.so

安装pgsql扩展时候报错如下： （不知道啥情况，先放着）

基本完成，配置nginx并上传代码

1.创建项目文件夹

1
2
3
4
5
cd /
mkdir www
cd www
mkdir web-osp
chmod -R 777 web-osp

代码用命令行或者工具同步进服务器对应文件夹

2.修改配置文件nginx.conf

    }
    location ~ /\.ht {

    }
}

重启php-fpm、nginx

部署基本完毕，尝试进入项目，出现两次502，记录如下

第一次 502 Bad Gateway

nginx配置和php-fpm端口不一致，改好，能登录

1
fastcgi_pass 127.0.0.1:9000;
第二次 502 Bad Gateway

登录后进入主页 502

查找问题

https://host.zzidc.com/wljc/928.html

查看是否是php-fpm的问题，找到正在使用的配置文件

appuser  28587 25750  0 14:46 pts/1    00:00:00 grep php-fpm

编辑php-fpm.conf

1
# /usr/local/php/etc/php-fpm.conf

没有 php-fpm.conf 的话

1
# cp php-fpm.conf.default php-fpm.conf

设置

request_terminate_timeout

request_terminate_timeout = 600

重启php-fpm，还是不行

去看php-fpm日志记录，发现日志没开，先打开日志记录

  • 1.修改php-fpm.conf中的配置**，如果没有请增加:

复制代码 代码如下:

1
2
3
4
[global]
error_log = log/php_error_log
[www]
catch_workers_output = yes
  • 2.修改php.ini中配置

，没有则增加:

复制代码 代码如下:

1
2
3
log_errors = On
error_log = "/usr/local/php/var/log/error_log"
error_reporting=E_ALL&~E_NOTICE
  • 3.重启php-fpm

当PHP执行错误时就能看到错误日志在”/usr/local/php56/var/log/php_error_log”中了

  • 4.浏览器进项目，然后查看看日志
1
2
# /usr/local/php56/var/log/php_error_log

重新装pgsql扩展
安装的时候不要make && make install
先 make， 然后make install

刷新网页

Call to undefined function bcdiv()

继续填坑

查找问题，没有安装扩展bcmath

同安装pgsql一样，安装后基本没发现其他问题

后续配置Apache，ldap集团单点登录

Apache的单点登录配置简单预热，详细看下一篇

cd /etc/httpd/conf/

sudo vim httpd-vhosts.conf
