Linux10.2 安装LNMP

Nginx安装

　　处理静态文件能力更强。

　　Nginx官网 nginx.org，最新版1.13，最新稳定版1.12
　　Nginx应用场景：web服务、反向代理、负载均衡
　　Nginx著名分支，淘宝基于Nginx开发的Tengine，使用上和Nginx一致，服务名，配置文件名都一样，和Nginx的最大区别在于Tenging增加了一些定制化模块，在安全限速方面表现突出，另外它支持对js，css合并
　　Nginx核心+lua相关的组件和模块组成了一个支持lua的高性能web容器openresty，参考  http://jinnianshilongnian.iteye.com/blog/2280928

　　

　　下载并解压安装包

cd /usr/local/src
wget http://nginx.org/download/nginx-1.12.1.tar.gz
tar zxf nginx-1.12.1.tar.g

　　编译安装

#自定义安装，无任何参数安装
[root@localhost nginx-1.12.1]# ./configure --prefix=/usr/local/nginx
[root@localhost nginx-1.12.1]# make && make install

./configure: error: the HTTP rewrite module requires the PCRE library.
 
安装pcre-devel与openssl-devel解决问题
 
yum -y install pcre-devel openssl openssl-devel

　　编辑启动脚本，更改权限

#编辑启动脚本

        echo $"Usage: $0 {start|stop|reload|restart|configtest}"
        RETVAL=1
esac
exit $RETVAL

#更改权限 
[root@localhost nginx-1.12.1]# chmod 755 /etc/init.d/nginx

　　开机自启

[root@localhost nginx-1.12.1]# chkconfig --add nginx
[root@localhost nginx-1.12.1]# chkconfig nginx on

　　修改配置文件

cd /usr/local/nginx/conf/ 
mv nginx.conf nginx.conf.bak

vim nginx.conf

            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
        }    
    }
}

　　启动服务

 #查看配置文件是否有错误
/usr/local/nginx/sbin/nginx -t

#启动服务
 /etc/init.d/nginx  start
 netstat -lntp |grep 80

　　php解析是因为在nginx配置文件中service部分配置了location ~ .php$ 语句，可以自行测试是否解析php。

[root@localhost ~]# vi /usr/local/nginx/html/1.php
<?php
    echo "test php scripts.";
?>
[root@localhost ~]# curl localhost/1.php
test php scripts.

安装nginx

yum安装

 　　 yum安装。使用nginx扩展源安装nginx，epel里面的nginx版本太老，先禁用了epel。

[root@localhost ~]# cat /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1

　　看下所有nginx的安装包

安装MySQL

　　若之前服务器有mysql，再次安装需要把之前mysql删除干净。MySQL数据文件夹可删可不删

#删除分三步
#先删除MySQL文件包
rm -rf /usr/local/mysql

#再删除启动文件
rm -rf /etc/init.d/mysqld

#删除配置文件
rm -rf  /etc/my.cnf

　　之后为安装MySQL，首先下载mysql二进制免编译包

[root@localhost src]# wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz 

　　再解压该二进制免编译包。

[root@localhost src]# tar -zxvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz 

　　移动解压后的文件，移动前确认目标地无MySQL文件夹

[root@localhost src]# ls /usr/local/mysql
ls: 无法访问/usr/local/mysql: 没有那个文件或目录
[root@localhost src]# mv mysql-5.6.35-linux-glibc2.5-x86_64 /usr/local/mysql

　　创建MySQL数据文件夹，并创建mysql用户

 useradd mysql
 mkdir /data/

　　编译安装mysql，出现两个OK则成功

 ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql

　　安装会出现一些错误

#error 1
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

#解决办法
[root@localhost mysql]# yum install -y libaio


#error 2
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
-bash: ./scripts/mysql_install_db: /usr/bin/perl: 坏的解释器: 没有那个文件或目录

#解决办法
[root@localhost mysql]# yum -y install autoconf

再次编译安装，验证输出
[root@localhost mysql]# echo $?
0

　　拷贝配置文件和启动脚本

#配置文件
[root@localhost mysql]# cp ./support-files/my-default.cnf  /etc/my.cnf 


#启动脚本
[root@localhost mysql]# cp ./support-files/mysql.server /etc/init.d/mysqld

　　修改配置文件和启动脚本，主要修改这两项

basedir
datadir

　　修改启动脚本权限为755，开机自启

[root@localhost mysql]# chmod 755 /etc/init.d/mysqld
[root@localhost mysql]# chkconfig --add mysqld

　　启动MySQL

[root@localhost mysql]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/data/mysql/localhost.localdomain.err'.
. SUCCESS! 

　　命令行方式启动

/usr/local/mysql/bin/mysqld_safe    --default-file=/etc/my.cnf  --user=mysql  --data=/data/mysql

　　杀进程可以用killall mysqld，系统会继续等待mysql传输数据，直到全部完成才会自动关闭。

　　在mysqld写数据的时候，如果杀死mysqld进程，发现杀不死，不要强制-9杀，有可能会直接导致正在传输的数据丢失，表损坏。

安装PHP

　　 和LAMP安装PHP方法有差别，需要开启php-fpm服务

　　下载php源码包

[root@localhost src]# wget http://cn2.php.net/distributions/php-5.6.30.tar.gz

　　解压

[root@localhost src]# tar zxf php-5.6.30.tar.gz 

　　创建用户

useradd -s /sbin/nologin php-fpm

　　编译安装

 ./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl  --with-openssl

　　安装错误见LAMP文件，其中未包含的错误有以下

configure: error: Please reinstall the libcurl distribution -
    easy.h should be in <curl-dir>/include/curl/

#解决方法

yum install -y curl curl-devel

　　最后make && make install  可能需要10分钟左右。

　　安装成功后

　　查看php文件发现，LAMP和LNMP的php文件是有区别的

#LNMP
[root@localhost php-5.6.30]# ls /usr/local/php-fpm/
bin  etc  include  lib  php  sbin  var
#多一个sbin和var文件
#sbin文件是存放php服务启动文件
[root@localhost php-5.6.30]# ls /usr/local/php-fpm/sbin/
php-fpm
#var里面放的是日志文件和存放pid
[root@localhost php-5.6.30]# ls /usr/local/php-fpm/var/
log  run

#LAMP
[root@chy002 ~]# ls /usr/local/php/
bin  etc  include  lib  php

　　-m 查看模块，-i 查看phpinfo，-t查看配置文件是否正确

#两个都可以

[root@localhost php-5.6.30]# /usr/local/php-fpm/bin/php  -m

[root@localhost php-5.6.30]# /usr/local/php-fpm/sbin/php-fpm  -m

　　拷贝修改配置文件，php.ini用来控制php某些功能

#拷贝生产环境下配置文件
[root@localhost etc]# cp php.ini-production /usr/local/php-fpm/etc/php.ini

#修改配置文件
[root@localhost etc]# mv php-fpm.conf.default php-fpm.conf

[root@localhost etc]#vi /usr/local/php/etc/php-fpm.conf
[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

　　拷贝启动脚本

[root@localhost etc]# cp /usr/local/src/php-5.6.30/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost etc]# chmod 755 /etc/init.d/php-fpm
[root@localhost etc]# chkconfig --add php-fpm
[root@localhost etc]# chkconfig php-fpm on
[root@localhost etc]# service php-fpm start
Starting php-fpm  done　

　　检测一下

[root@localhost etc]# ps aux|grep php
