LAMP^%LNMP环境搭建

lnmp环境搭建

前置条件

1. 操作系统安装：CentOS 6.8 64位最小化安装。

2. 配置好IP、DNS、网关、主机名

   cd /etc/sysconfig/network-scripts mv ifcfg-eth0 ifcfg-eth1

   cat /etc/udev/rules.d/70-persistent-net.rules

   vim ifcfg-eth1

   把mac地址复制过来 onboot = yes

3. 配置防火墙，开启80、3306端口

vim /etc/sysconfig/iptables
关闭访问墙
service iptables stop
/etc/init.d/iptables restart #最后重启防火墙使配置生效

1. 关闭SELinux

   vi /etc/selinux/config
   SELINUX=enforcing #注释掉

   SELINUXTYPE=targeted #注释掉

   SELINUX=disabled #增加
   :wq! #保存退出
   setenforce 0 #使配置立即生效

系统约定

软件源代码包存放位置：/root/lnmp
源码包编译安装位置：/usr/local/软件名
数据库数据文件存储路径/data/mysql

系统软件包版本

#已经附加在文件夹中

安装编译工具及库文件

软件安装篇

1、安装cmake
tar -zxvf cmake-2.8.7.tar.gz
cd cmake-2.8.7
./configure --prefix=/usr/local/cmake
make #编译
make install #安装
vim /etc/profile 在path路径中增加cmake执行文件路径
export PATH=$PATH:/usr/local/cmake/bin
source /etc/profile使配置立即生效

2、安装pcre
tar -zxvf pcre-8.39.tar.gz
cd pcre-8.39
./configure --prefix=/usr/local/pcre 
make && make install

3、安装libmcrypt
tar -zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8
./configure #配置
make #编译
make install #安装

4、安装gd库
tar -zxvf gd-2.0.36RC1.tar.gz
cd gd-2.0.36RC1
./configure --enable-m4_pattern_allow --prefix=/usr/local/gd --with-jpeg=/usr/lib --with-png=/usr/lib --with-xpm=/usr/lib --with-freetype=/usr/lib --with-fontconfig=/usr/lib 
make #编译
make install #安装

5、安装Mysql
groupadd mysql #添加mysql组
useradd -g mysql mysql -s /sbin/nologin #创建用户mysql并加入到mysql组，不允许mysql用户直接登录系统
mkdir -p /var/mysql/data #创建MySQL数据库存放目录
chown -R mysql:mysql /var/mysql/data #设置MySQL数据库目录权限

tar -zxvf mysql-5.5.28.tar.gz #解压

cd mysql-5.5.28
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/var/mysql/data \
-DMYSQL_USER=mysql -DMYSQL_TCP_PORT=3306

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_DATADIR=/var/mysql/data -DMYSQL_USER=mysql -DMYSQL_TCP_PORT=3306

make
make install

cp ./support-files/my-huge.cnf /etc/my.cnf #拷贝配置文件（注意：如果/etc目录下面默认有一个my.cnf，直接覆盖即可）

vi /etc/my.cnf #编辑配置文件,在 [mysqld] 部分增加
datadir = /var/mysql/data #添加MySQL数据库路径
cd /usr/local/mysql
groupadd mysql
useradd -g mysql mysql -s /sbin/nologin
./scripts/mysql_install_db --user=mysql #生成mysql系统数据库
cd /root/lnmp/mysql-5.5.28
cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld #把Mysql加入系统启动
chmod 755 /etc/init.d/mysqld #增加执行权限
chkconfig mysqld on #加入开机启动
init.d  就是  /etc/rc.d/init.d  软链接
vi /etc/rc.d/init.d/mysqld #编辑
basedir=/usr/local/mysql #MySQL程序安装路径
datadir=/var/mysql/data #MySQl数据库存放目录
service mysqld start #启动,可能无法写入pid文件，注意将mysql用户权限加入至/usr/local/mysql
chown -R mysql:mysql /usr/local/mysql

vi /etc/profile #把mysql服务加入系统环境变量：在最后添加下面这一行
export PATH=$PATH:/usr/local/cmake/bin:/usr/local/mysql/bin
source /etc/profile #使配置立即生效

mkdir /var/lib/mysql #创建目录
ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock #添加软链接
#先启动服务 service mysqld start
mysql_secure_installation #设置Mysql密码，根据提示按Y 回车输入2次密码
/usr/local/mysql/bin/mysqladmin -u root -p password "123456" #或者直接修改密码
到此，mysql安装完成！

6、安装 nginx
tar -zxvf nginx-1.11.5.tar.gz
groupadd www #添加www组
useradd -g www www -s /sbin/nologin #创建nginx运行账户www并加入到www组，不允许www用户直接登录系统
openssl-1.1.0b.tar.gz
cd nginx-1.11.5
./configure --prefix=/usr/local/nginx --without-http_memcached_module --user=www --group=www   --with-http_stub_status_module --with-openssl=/lnmp/src/openssl-1.1.0b --with-pcre=/lnmp/src/pcre-8.39   --with-http_ssl_module
注意:--with-pcre=/lnmp/src/pcre-8.39指向的是源码包解压的路径，而不是安装的路径，否则会报错

make
make install
/usr/local/nginx/sbin/nginx #启动nginx
设置nginx开启启动
vi /etc/rc.d/init.d/nginx #编辑启动文件添加下面内容
=======================================================
#!/bin/bash

=======================================================

7、安装php
cd /lnmp/src
tar -jxvf php-7.0.7.tar.bz2 
cd php-7.0.7
./configure --prefix=/usr/local/php7 --with-config-file-path=/usr/local/php7/etc  --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mysqlnd --with-mysql-sock=/usr/local/mysql/mysql.sock --with-gd --with-iconv --with-zlib --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --enable-session --with-mcrypt --with-curl --with-jpeg-dir --with-freetype-dir   --with-pdo-mysql=/usr/local/mysql/

make #编译,，若遇到make: *** [ext/fileinfo/libmagic/apprentice.lo] 错误 ，这加参数–-disable-fileinfo
make install #安装

cd /root/lnmp/php-7.0.7
cp php.ini-production /usr/local/php7/etc/php.ini #复制php配置文件到安装目录
rm -rf /etc/php.ini #删除系统自带配置文件
ln -s /usr/local/php7/etc/php.ini /etc/php.ini #添加软链接

cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf #拷贝模板文件为php-fpm配置文件
cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf  

vi /usr/local/php7/etc/php-fpm.d/www.conf  #编辑

user = www #设置php-fpm运行账号为www
group = www #设置php-fpm运行组为www

vim /usr/local/php7/etc/php-fpm.conf
pid = run/php-fpm.pid #取消前面的分号

加入服务并开机启动 ，设置 php-fpm开机启动
#cp /lnmp/src/php-7.0.7/sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm #拷贝php-fpm到启动目录
chmod +x /etc/rc.d/init.d/php-fpm #添加执行权限
chkconfig php-fpm on #设置开机启动

vi /usr/local/php7/etc/php.ini #编辑配置文件

这里暂时不给禁用
找到：disable_functions =
修改为：disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,escapeshellcmd,dll,popen,disk_free_space,checkdnsrr,checkdnsrr,getservbyname,getservbyport,disk_total_space,posix_ctermid,posix_get_last_error,posix_getcwd, posix_getegid,posix_geteuid,posix_getgid, posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid, posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit, posix_getsid,posix_getuid,posix_isatty, posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid,posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname

列出PHP可以禁用的函数，如果某些程序需要用到这个函数，可以删除，取消s禁用

找到：;date.timezone =
修改为：date.timezone = PRC #设置时区
找到：expose_php = On
修改为：expose_php = OFF #禁止显示php版本的信息
找到：short_open_tag = Off
修改为：short_open_tag = ON #支持php短标签

八、配置nginx支持php
vi /usr/local/nginx/conf/nginx.conf
修改/usr/local/nginx/conf/nginx.conf 配置文件,需做如下修改

    user www www; #首行user去掉注释,修改Nginx运行组为www www；必须与/usr/local/php/etc/php-fpm.conf中的user,group配置相同，否则php运行出错
    user www www;
    worker_processes 1;
    events {
    worker_connections 1024;
    }
    http {
        include mime.types;
        default_type application/octet-stream;
        sendfile on;
        keepalive_timeout 65;
        server {
            listen 80;
            server_name localhost;
                location / {
                root /data/www;
                index index.php index.html index.htm;
                }
                location ~ \.php$ {
                root /data/www;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param /data/www/ $document_root$fastcgi_script_name;
                include fastcgi_params;
                }
        }
    }

    mkdir -p /data/www
    chown www:www /data/www/ -R #设置目录所有者
    chmod 700 /data/www -R #设置目录权限

服务器相关操作命令
service nginx restart #重启nginx
service mysqld restart #重启mysql
/usr/local/php/sbin/php-fpm #启动php-fpm
/etc/rc.d/init.d/php-fpm restart #重启php-fpm
/etc/rc.d/init.d/php-fpm stop #停止php-fpm
/etc/rc.d/init.d/php-fpm start #启动php-fpm
