企业级LNMP分离式部署

安装MySQL数据库

 

安装步骤介绍

本例采用MySQL二进制安装包进行安装演示

(1) 创建mysql用户的账号

 

1. [root@mysql ~]# groupadd mysql
2. [root@mysql ~]# useradd -s /sbin/nologin -g mysql -M mysql
3. [root@localhost ~]# tail -1 /etc/passwd
4. mysql:x:500:501::/home/mysql:/sbin/nologin
5. [root@mysql ~]# id mysql
6. uid=500(mysql) gid=501(mysql) groups=501(mysql)

(2)获取MySQL二进制软件包

百度云盘：http://pan.baidu.com/s/1hrBCzsC 
提取码：4yjf

(3) 采用二进制方式安装MySQL

1. [root@mysql ~]# tar xf mysql-5.5.32-linux2.6-x86_64.tar.gz -C /usr/local/
2. [root@mysql ~]# cd /usr/local/
3. [root@mysql local]# mv mysql-5.5.32-linux2.6-x86_64 mysql-5.5.32
4. [root@mysql local]# ln -s mysql-5.5.32 mysql
5. [root@mysql local]# ls
6. bin etc games include lib lib64 libexec mysql mysql-5.5.32 sbin share src
7. [root@mysql local]# cd /usr/local/mysql
8. [root@mysql mysql]# ls
9. bin data include lib mysql-test scripts sql-bench
10. COPYING docs INSTALL-BINARY man README share support-files
11. #提示：
12. 二进制安装包，仅需要解压就可以了，不需要执行cmake/configure,make,make install等过程

（4）初始化MySQL配置文件my.cnf

 

1. [root@mysql mysql]# ls -l support-files/*.cnf
2. -rw-r--r--. 1 7161 wheel 4691 Jun 19 2013 support-files/my-huge.cnf
3. -rw-r--r--. 1 7161 wheel 19759 Jun 19 2013 support-files/my-innodb-heavy-4G.cnf
4. -rw-r--r--. 1 7161 wheel 4665 Jun 19 2013 support-files/my-large.cnf
5. -rw-r--r--. 1 7161 wheel 4676 Jun 19 2013 support-files/my-medium.cnf
6. -rw-r--r--. 1 7161 wheel 2840 Jun 19 2013 support-files/my-small.cnf
7. [root@mysql mysql]# /bin/cp support-files/my-small.cnf /etc/my.cnf

提示： 
- support-files下有my.cnf的各种配置样例。 
- 使用cp全路径/bin/cp，可实现拷贝而不出现替换提示，即如果有重名文件会直接覆盖 
- 本例为测试安装环境，因此选择参数配置小的my-small.cnf配置模版，如果是生产环境可以根据硬件选择更高级的配置文件，上述配置文件模版对硬件的要求从低到高依次为

 

1. my-medium.cnf (最低)
2. my-small.cnf
3. my-large.cnf
4. my-huge.cnf
5. my-innodb-heavy-4G.cnf（最高）

（5）初始化MySQL数据库文件

初始化命令如下

 

1. [root@mysql mysql]# mkdir -p /usr/local/mysql/data
2. [root@mysql mysql]# chown -R mysql.mysql /usr/local/mysql
3. [root@mysql mysql]# yum -y install libaio
4. [root@mysql mysql]# /usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
5. #初始化MySQL数据库文件，会有很多信息提示，如果没有ERROR级别的错误，会有两个OK的字样，表示初始化成功，否则就要解决初始化的问题

 

配置并启动MySQL数据库

（1）设置MySQL启动脚本，命令如下

 

1. [root@mysql mysql]# cp support-files/mysql.server /etc/init.d/mysqld
2. #拷贝MySQL启动脚本到MySQL的命令路径
3. [root@mysql mysql]# chmod +x /etc/init.d/mysqld
4. #使脚本可执行

（2）MySQL二进制默认安装路径是/usr/local/mysql，启动脚本里是/usr/local/mysql。如果安装路径不同，那么脚本里路径等都需要替换 
（3）启动MySQL数据库，命令如下：

 

1. [root@mysql mysql]# /etc/init.d/mysqld start
2. Starting MySQL... SUCCESS!
3. [root@mysql mysql]# netstat -antup | grep mysql
4. tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 1347/mysqld

如果发现3306端口没起来，请tail -100 /usr/local/mysql/data/主机名.err查看日志信息，看是否有报错信息，然后根据相关错误提示进行调试。经常查看服务运行日志是个很好的习惯，也是高手的习惯。

（4）设置MySQL开机自启动，命令如下：

1. [root@mysql mysql]# chkconfig --add mysqld
2. [root@mysql mysql]# chkconfig mysqld on
3. [root@mysql mysql]# chkconfig --list mysqld
4. mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off

（5）配置mysql命令的全局使用路径，命令如下：

 

1. [root@mysql mysql]# ln -s /usr/local/mysql/bin/* /usr/local/bin/
2. [root@mysql mysql]# which mysqladmin
3. /usr/local/bin/mysqladmin

（6）登陆MySQL测试，命令如下：

 

1. [root@mysql mysql]# mysql
2. Welcome to the MySQL monitor. Commands end with ; or \g.
3. Your MySQL connection id is 1
4. Server version: 5.5.32 MySQL Community Server (GPL)
6. Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.
8. Oracle is a registered trademark of Oracle Corporation and/or its
9. affiliates. Other names may be trademarks of their respective
10. owners.
12. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

 

MySQL安全配置

（1）为MySQL的root用户设置密码，命令如下：

1. [root@mysql mysql]# mysqladmin -uroot password '666666'
2. [root@mysql mysql]# mysql -uroot -p666666
3. Welcome to the MySQL monitor. Commands end with ; or \g.
4. Your MySQL connection id is 4
5. Server version: 5.5.32 MySQL Community Server (GPL)
7. Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.
9. Oracle is a registered trademark of Oracle Corporation and/or its
10. affiliates. Other names may be trademarks of their respective
11. owners.
13. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

（2）清理无用的MySQL用户及库，命令如下：

1. mysql> select user,host from mysql.user;
2. +------+-----------+
3. | user | host |
4. +------+-----------+
5. | root | 127.0.0.1 |
6. | root | ::1 |
7. | | localhost |
8. | root | localhost |
9. | | mysql |
10. | root | mysql |
11. +------+-----------+
12. 6 rows in set (0.00 sec)
14. mysql> drop user "root"@"::1";
15. Query OK, 0 rows affected (0.00 sec)
17. mysql> drop user ""@"localhost";
18. Query OK, 0 rows affected (0.05 sec)
20. mysql> select user,host from mysql.user;
21. +------+-----------+
22. | user | host |
23. +------+-----------+
24. | root | 127.0.0.1 |
25. | root | localhost |
26. | | mysql |
27. | root | mysql |
28. +------+-----------+
29. 4 rows in set (0.00 sec)

 

安装nginx

 

nginx的编译安装部署

1. [root@nginx ~]# mount /dev/sr0 /media/cdrom/
2. mount: block device /dev/sr0 is write-protected, mounting read-only

10. [root@nginx nginx-1.10.2]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/ #给命令做软连接，以便PATH能找到
11. [root@nginx nginx-1.10.2]# /usr/local/nginx/sbin/nginx #启动nginx

 

配置nginx配置文件

1. [root@nginx conf]# cat nginx.conf.default | egrep -v "#|^$" > nginx.conf
2. [root@nginx conf]# vim nginx.conf
3. [root@nginx conf]# cat nginx.conf
4. worker_processes 1;
5. events {
6. worker_connections 1024;
7. }
8. http {
9. include mime.types;
10. default_type application/octet-stream;
11. sendfile on;
12. keepalive_timeout 65;
13. server {
14. listen 80;
15. server_name www.yunjisuan.com;
17. root /www;
18. location / {
19. index index.html index.htm;
20. }
21. error_page 500 502 503 504 /50x.html;
22. location = /50x.html {
23. root html;
24. }
25. }
26. }
28. # 检查配置文件
29. [root@nginx conf]# /usr/local/nginx/sbin/nginx -t
30. nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
31. nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
33. #加入映射文件
34. [root@nginx conf]# echo "`hostname -I` www.yunjisuan.com" >> /etc/hosts
35. [root@nginx conf]# cat /etc/hosts
36. 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
37. ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
38. 192.168.200.20 www.yunjisuan.com

 

添加网页

1. [root@nginx conf]# mkdir /www
2. [root@nginx conf]# echo "`hostname -I` www.yunjisuan.com" >> /www/index.html
3. [root@nginx conf]# chown -R www.www /www/ #PHP的程序用户也要弄成www
4. [root@nginx conf]# curl www.yunjisuan.com
5. 192.168.200.20 www.yunjisuan.com

 

安装PHP

 

检查安装PHP所需的lib库

PHP程序在开发及运行时会调用一些诸如zlib，gd等函数库，因此需要确认lib库是否已经安装，执行过程如下：

 

1. [root@PHP ~]# rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel
2. [root@PHP ~]# rpm -qa freetype-devel libpng-devel gd libcurl-devel libxslt-devel

提示：

1)每个lib一般都会存在对应的以“*-devel”命名的包，安装lib对应的-devel包后，对应的lib包就会自动安装好，例如安装gd-devel时就会安装gd。 
2)这些lib库不是必须安装的，但是目前的企业环境下一般都需要安装。否则，PHP程序运行时会出现问题，例如验证码无法显示等。

执行下面命令安装相关的lib软件包

 

1. [root@PHP ~]# yum -y install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel
2. [root@PHP ~]# yum -y install freetype-devel libpng-devel gd libcurl-devel libxslt-devel

安装后的结果如下：

1. [root@PHP ~]# rpm -qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel
2. libxml2-devel-2.7.6-14.el6.x86_64
3. zlib-devel-1.2.3-29.el6.x86_64
4. libjpeg-turbo-devel-1.2.1-1.el6.x86_64
5. #这里仅缺少libiconv-devel包
6. [root@PHP ~]# rpm -qa freetype-devel libpng-devel gd libcurl-devel libxslt-devel
7. libxslt-devel-1.1.26-2.el6_3.1.x86_64
8. libcurl-devel-7.19.7-37.el6_4.x86_64
9. libpng-devel-1.2.49-1.el6_2.x86_64
10. gd-2.0.35-11.el6.x86_64
11. freetype-devel-2.3.11-14.el6_3.1.x86_64

从以上结果看出，仅有libiconv-devel这个包没有安装，因为默认的yum源没有此包，后面会编译安装。

 

安装yum无法安装的libiconv库

 

1. [root@PHP ~]# yum -y install wget
2. [root@PHP ~]# wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
3. [root@PHP ~]# ls
4. anaconda-ks.cfg install.log install.log.syslog libiconv-1.14.tar.gz
5. [root@PHP ~]# tar xf libiconv-1.14.tar.gz -C /usr/src/
6. [root@PHP ~]# cd /usr/src/libiconv-1.14/
7. [root@PHP libiconv-1.14]# ./configure --prefix=/usr/local/libiconv && make && make install

 

安装libmcrypt库

 

1. 推荐使用简单的在线yum的方式安装：wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
2. [root@PHP libiconv-1.14]# yum -y install libmcrypt-devel

 

安装mhash加密扩展库

 

1. 推荐使用简单的在线yum的方式安装：wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
2. [root@PHP ~]# yum -y install mhash

 

安装mcrvpt加密扩展库

1. 推荐使用简单的在线yum的方式安装：wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
2. [root@PHP ~]# yum -y install mcrypt

 

开始安装PHP（FastCGI方式）服务

 

获取PHP软件包

 

1. [root@PHP ~]# wget http://cn2.php.net/get/php-5.3.28.tar.gz/from/this/mirror

1. [root@PHP ~]# useradd -s /sbin/nologin -M www
2. [root@PHP ~]# id www
3. uid=500(www) gid=500(www) groups=500(www)
5. [root@PHP ~]# tar xf php-5.3.28.tar.gz -C /usr/src/
6. [root@PHP ~]# cd /usr/src/php-5.3.28/
7. [root@PHP php-5.3.28]# ./configure --prefix=/usr/local/php5.3.28 --with-mysql=mysqlnd --with-iconv-dir=/usr/local/libiconv --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fpm --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --enable-short-tags --enable-zend-multibyte --enable-static --with-xsl --with-fpm-user=www --with-fpm-group=www --enable-ftp

-devel是安装前面命令有关的所有包 
yum install openssl openssl-devel 
执行上述命令后，最后的正确输出提示为下图 

编译PHP

正确执行前文配置PHP软件的./configure系列命令后，就可以编译PHP软件了，具体操作过程如下：

 

1. [root@PHP php-5.3.28]# ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/ #分离式不用这步
2. [root@PHP php-5.3.28]# touch ext/phar/phar.phar #分离式不用这步
