lnmp架构的搭建

实验环境

redhat6.5
iptables和selinux关闭
准备条件：虚拟机大约需要3G的内存
简介：
LNMP就是Linux+Nginx+MySQL+PHP
Nginx会把用户的动态请求交给php服务去处理，这个php服务就会去和数据库进行交互。用户的静态请求Nginx会直接处理。

nginx

mysql

1、编译安装
[root@server5 ~]# tar zxf mysql-boost-5.7.17.tar.gz 
[root@server5 ~]# yum install -y cmake-2.8.12.2-4.el6.x86_64.rpm 
[root@server5 ~]# cd mysql-5.7.17/
[root@server5 mysql-5.7.17]# cmake 
-DCMAKE_INSTALL_PREFIX=/usr/local/lnmp/mysql -DMYSQL_DATADIR=/usr/local/lnmp/mysql/data -DMYSQL_UNIX_ADDR=/usr/local/lnmp/mysql/data/mysql.sock -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 
-DDEFAULT_CHARSET=utf8 
-DDEFAULT_COLLATION=utf8_general_ci 
-DEXTRA_CHARSETS=all

cmake 时有报错，根据报错内容解决依赖性

[root@server5 mysql-5.7.17]# yum install gcc gcc-c++ -y

[root@server5 mysql-5.7.17]# cmake 
-DCMAKE_INSTALL_PREFIX=/usr/local/lnmp/mysql -DMYSQL_DATADIR=/usr/local/lnmp/mysql/data -DMYSQL_UNIX_ADDR=/usr/local/lnmp/mysql/data/mysql.sock -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 
-DDEFAULT_CHARSET=utf8 
-DDEFAULT_COLLATION=utf8_general_ci 
-DEXTRA_CHARSETS=all 
-DWITH_BOOST=boost/boost_1_59_0/  #添加内容Tab补齐

[root@server5 mysql-5.7.17]# rm -fr CMakeCache.txt   
[root@server5 mysql-5.7.17]# yum install ncurses-devel -y

注意:每解决完一次错误,就应删除缓存 rm -fr CMakeCache.txt

[root@server5 mysql-5.7.17]# rm -fr CMakeCache.txt
 [root@server5 mysql-5.7.17]# yum install -y bison
[root@server5 mysql-5.7.17]# cmake 
-DCMAKE_INSTALL_PREFIX=/usr/local/lnmp/mysql -DMYSQL_DATADIR=/usr/local/lnmp/mysql/data -DMYSQL_UNIX_ADDR=/usr/local/lnmp/mysql/data/mysql.sock -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 
-DDEFAULT_CHARSET=utf8 
-DDEFAULT_COLLATION=utf8_general_ci 
-DEXTRA_CHARSETS=all 
-DWITH_BOOST=boost/boost_1_59_0/
[root@server5 mysql-5.7.17]# make
[root@server5 mysql-5.7.17]# make install
2、安全初始化
[root@server5 ~]# cd /usr/local/lnmp/mysql
[root@server5 mysql]# rpm -qa | grep mysql
mysql-libs-5.1.71-1.el6.x86_64
[root@server5 mysql]# cd support-files/
[root@server5 support-files]# cp  my-default.cnf /etc/my.cnf 
cp: overwrite `/etc/my.cnf'? y
[root@server5 support-files]# vim /etc/my.cnf
 18 basedir = /usr/local/lnmp/mysql
 19 datadir = /usr/local/lnmp/mysql/data
 20 port = 3306
 21 # server_id = .....
 22 socket = /usr/local/lnmp/mysql/data/mysql.sock
[root@server5 support-files]# file mysql.server 
mysql.server: POSIX shell script text executable
[root@server5 support-files]# cp mysql.server /etc/init.d/mysqld
[root@server5 support-files]# cd ..
[root@server5 mysql]# groupadd -g 27 mysql
[root@server5 mysql]# useradd -u 27 -g 27 -M -d /usr/local/lnmp/mysql/data -s /sbin/nologin mysql
[root@server5 mysql]# cd
[root@server5 ~]# vim .bash_profile  //mysql添加到环境变量
 10 PATH=$PATH:$HOME/bin:/usr/local/lnmp/mysql/bin
[root@server5 ~]# source .bash_profile  //生效
[root@server5 ~]# cd /usr/local/lnmp/mysql
[root@server5 mysql]# chown mysql.mysql -R .
[root@server5 mysql]# mysqld --initialize --user=mysql  //以mysql用户身份初始化，会生成一个初始密码

[root@server5 mysql]# chown root.root -R .  //为了安全将mysql目录的所有者改为root
[root@server5 mysql]# chown mysql data/ -R 
[root@server5 mysql]# /etc/init.d/mysqld start
Starting MySQL.. SUCCESS! 
[root@server5 mysql]# mysql_secure_installation
Securing the MySQL server deployment.

Enter password for user root:  //输入执行mysqld --initialize --user=mysql时的密码

The existing password for the user account root has expired. Please set a new password.

New password: //添加新密码

Re-enter new password: 

VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: No  //选择No
Using existing password for root.
Change the password for root ? ((Press y|Y for Yes, any other key for No) : 

 ... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : 

 ... skipping.

Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : 

 ... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : 

 ... skipping.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : 

 ... skipping.
All done! 
[root@server5 mysql]# mysql -p
Enter password:

nginx和mysql结合安装论坛

[root@server5 ~]# unzip Discuz_X3.2_SC_UTF8.zip -d /usr/local/lnmp/nginx/html/
[root@server5 nginx]# cd html
[root@server5 html]# ls
50x.html  index.html  index.php  readme  upload  utility
[root@server5 html]# mv upload/ bbs
[root@server5 html]# cd bbs

浏览器访问172.25.35.55/bbs:

提示有错误，添加加权限

[root@server5 bbs]# chmod 777 config/ data/ uc_server/ uc_client/ -R

即可点击下一步：

提示数据库连接错误，有可能是脚本文件不能访问
