12.1 LNMP架构介绍
1. 和LAMP不同的是,提供web服务的是Nginx
2. 并且php是作为一个独立服务存在的,这个服务叫做php-fpm
3. Nginx直接处理静态请求,动态请求会转发给php-fpm
12.2 MySQL安装
删除之前安装的mysql
1. 查看之前安装mysql是否开启 :[root@hao-01 ~]# ps aux |grep mysql
2. 关闭之前安装的mysql服务 :[root@hao-01 ~]# service mysqld stop
3. 删除之前安装的mysql目录 :[root@hao-01 ~]# rm -rf /usr/local/mysql
4. 删除之前安装的mysql启动脚本 :[root@hao-01 ~]# rm -rf /etc/init.d/mysqld
5. 删除之前安装的mysql目录 :[root@hao-01 ~]# rm -rf /data/mysql
安装mysql(以下以MySQL5.7为例,与5.6的不同点在于会自动生成密码)
安装下载工具: yum -y install wget
wget 是一个从网络上自动下载文件的自由工具,支持通过 HTTP、HTTPS、FTP 三个最常见的 TCP/IP协议 下载,并可以使用 HTTP 代理
1. 进入下载安装包目录 :[root@hao-01 ~]# cd /usr/local/src/
2.下载mysql安装包 :[root@hao-01 src]# wget http://mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz # 部分软件更新下载:[r.aminglinux.com]
3. 解包解压mysql包 :[root@hao-01 src]# tar zxvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
4. 解压的mysql包,移动到/usr/local/目录下,并重命名为mysql:
(注意:/usr/local/目录下,不能已经存在mysql目录,
如果存在,再用mv移动,会放在已存的mysql目录下面,而不会覆盖!!!)
[root@hao-01 src]# mv mysql-5.6.35-linux-glibc2.5-x86_64 /usr/local/mysql
5. 列出mysql目录下所有文件目录(检查是否和下图一样) :
[root@hao-01 local]# ls /usr/local/mysql
[root@localhost mysql]# ls /usr/local/mysql
bin COPYING docs include lib man README share support-files
6. 进入mysql目录下 :[root@hao-01 src]# cd /usr/local/mysql
7. 创建mysql用户 :
[root@hao-01 mysql]#groupadd mysql #创建用户组
[root@hao-01 mysql]# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql ---新建msyql用户禁止登录shell
8. 根目录下,创建data目录,如果有/data目录了,可以不在创建 :
(注意:如果根目录下已存在data目录,一定要把/data里的mysql目录先删除!!!)
[root@hao-01 mysql]# rm -rf /data/mysql
[root@hao-01 mysql]#mkdir -p /data/mysql
改变目录属有者
[root@hao-01 mysql]#cd /usr/local/mysql
[root@hao-01 mysql]#pwd
[root@hao-01 mysql]#chown -R mysql .
[root@hao-01 mysql]#chgrp -R mysql .
[root@hao-01 mysql]#chown -R mysql /data/mysql
9. 安装依赖包 :
[root@hao-01 mysql]# yum install -y perl-Data-Dumper
[root@hao-01 mysql]# yum install -y libaio
10.配置参数
[root@hao-01 mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql #注意末尾生成的临时密码
[root@localhost mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

[root@hao-01 mysql]#bin/mysql_ssl_rsa_setup --datadir=/data/mysql
检验上一条命令执行是否有错?(数值0为没问题) :[root@hao-01 mysql]# echo $?
11. 编辑my.cnf配置文件 :
# cd /usr/local/mysql/support-files
# cp my-default.cnf /etc/my.cnf # MySQL的my.cnf文件不再需要(解决5.7.18下没有my-default.cnf)
# cp mysql.server /etc/init.d/mysql
# vim /etc/init.d/mysql
修改以下内容:
basedir=/user/local/mysql
datadir=/data/mysql
12. 启动mysqld服务:[root@hao-01 mysql]# /etc/init.d/mysql start
[root@localhost support-files]# /etc/init.d/mysql start
Starting MySQL.2018-10-20T15:50:18.565074Z mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.
ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).
解决办法:mv /etc/my.cnf /etc/my.cnf.bak 我是使用源码在虚拟机上安装的MySQL,安装目录为/usr/local/mysql/,相关配置文件都保存在此目录。并且有检查/etc/my.cnf文件是否存在(存在就将其重命名/删除)。
[root@localhost mysql]# /etc/init.d/mysql start
Starting MySQL.Logging to '/data/mysql/localhost.localdomain.err'.
. SUCCESS!
9启动mysql
# /etc/init.d/mysql start #--登陆
# mysql -hlocalhost -uroot -p
--如果出现:-bash: mysql: command not found
--就执行: # ln -s /usr/local/mysql/bin/mysql /usr/bin --没有出现就不用执行
--输入第6步生成的临时密码
--修改密码
mysql> set password=password('root');
--使用grant all privileges on来更改用户对应某些库的远程权限
mysql>grant all privileges on *.* to 'root'@'%' identified by 'root'; # mysql数据库设置远程连接权限
mysql>flush privileges;
grant all privileges on *.* to 'root'@'%' identified by 'root';

flush privileges;
--查看表
mysql> use mysql;
mysql> select host,user from user;
--这里就可以使用远程连接测试了;
10添加系统路径
# vim /etc/profile
添加:
export PATH=/usr/local/mysql/bin:$PATH
如下:
# source /etc/profile
11配置mysql自动启动
# chmod 755 /etc/init.d/mysql
# chkconfig --add mysql
# chkconfig --level 345 mysql on
搜索mysql进程,查看是否启动 ?[root@hao-01 mysql]# ps aux |grep mysql
查看mysql对应的端口号(3306) :[root@hao-01 mysql]# netstat -lntp # yum install -y net-tools
[root@localhost mysql]# netstat -lntp
Active Internet connections (only servers)

补充:
--退出mysql命令窗口 #exit
--查看mysql状态 #service mysql status
--停止mysql #service mysql stop
--启动mysql #service mysql start
附my.cnf(这是一个配置mysql配置文件,暂时可以不用管,如你想钻研 你可以百度或google “mysql my.cnf 配置详情”)
12.3-12.4 PHP安装(上下)
1. 进入下载安装包目录 :[root@hao-01 ~]# cd /usr/local/src/
2. 下载php-5.6.30版本安装包 :[root@hao-01 src]# wget http://cn2.php.net/distributions/php-5.6.32.tar.bz2
3. 解包解压php安装包:[root@hao-01 src]# tar -jxvf php-5.6.32.tar.bz2
[root@localhost src]# tar -jxvf php-5.6.32.tar.bz2
tar (child): bzip2:无法 exec: 没有那个文件或目录
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now解决办法 安装bzip2工具 yum search bzip2 //查询安装包 yum -y install bzip2.x86_64
1. rpm -qa|grep 软件包缩写 #查找软件
2. rpm -ql 软件包完整名 #显示安装地址
4. 进入php目录下 :[root@hao-01 src]# cd php-5.6.32
5. 如果之前编译过php-5.6.30包,进入这个包下解除删除之前的编译 :[root@hao-01 php-5.6.32]# make clean
如果是第一次或者重新下载的PHP包,不用此步骤
6. 编译 :
[root@hao-01 php-5.6.32]# ./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
[root@localhost php-5.6.32]# ./configure --prefix=/usr/local/php-fpm --with-.....
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: --with-openssl

If configure fails try --with-vpx-dir=<DIR>
configure: error: jpeglib.h not found.故障排除:rpm -qa | grep libjpeg 表示没有 并 yum -y install libjpeg-turbo libjpeg-devel 并 重新执行安装命令
configure: error: png.h not found.
故障排除: yum -y install libpng 并 yum -y install libpng-devel并 重新执行安装命令
If configure fails try --with-xpm-dir=<DIR>
configure: error: freetype-config not found.故障排除:yum -y install freetype-devel 并 重新执行安装命令
configure: error: mcrypt.h not found. Please reinstall libmcrypt.
故障排除:yum install -y epel-release 并 yum install -y libmcrypt-devel
两个不能一起安装,因为CentOs6默认的yum源没有libmcrypt-devel这个包,只能借助epel的yum源,所以先epel,再libmcrypt
7. 检验上一条命令执行是否有错?(数值0为没问题)[root@hao-01 mariadb]# echo $?
11. make和make install执行 :[root@hao-01 php-5.6.30]# make && make install #(编译速度有点慢)

15. 给php-fpm(启动脚本) 设定755权限 :[root@hao-01 php-5.6.32]# chmod 755 /etc/init.d/php-fpm #启动脚本
16. 添加php-fpm服务 到服务列表 :[root@hao-01 php-5.6.32]# chkconfig --add php-fpm
17. 设定 php-fpm服务 开机启动 :[root@hao-01 php-5.6.32]# chkconfig php-fpm on
18. 创建php-fpm用户 :[root@hao-01 php-5.6.32]# useradd php-fpm
19. 检测php-fpm配置文件是否有错 ?[root@hao-01 php-5.6.30]# /usr/local/php-fpm/sbin/php-fpm -t
20. 启动php-fpm服务 :[root@hao-01 php-5.6.30]# service php-fpm start
[root@localhost php-5.6.32]# service php-fpm start

21. 搜索php-fpm服务是否启动 ?[root@hao-01 php-5.6.30]# ps aux |grep php-fpm
12.5 Nginx介绍
1. Nginx官网 nginx.org,最新版1.13,最新稳定版1.12
2. Nginx应用场景:web服务、反向代理(代理一台)、负载均衡(代理两台)
3. 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
4. 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
