Linux下安装PHP+Nginx+Msql

安装Nginx:

1.先指定个文件存放位置  usr/local/src

2. 下载nginx,  wget http://nginx.org/download/nginx-1.12.0.tar.gz

3.解压：tar zxf nginx......

4.进入到nginx目录下，不清楚如何操作可以查看帮助(./configure --help)

　　此时如果安装nginx会报未安装pcre,zlib类库，YUM找一下安装起来，

　　yum search pcre

　　yum install pcre pcre-devel 确认Y下载并安装

　　yum install zlib zlib-devel

指定安装目录：./configure --prefix=/usr/local/nginx

　　编译：make && make install

此时安装成功,接下来要启动nginx,先去nginx安装目录下

(查看端口占用：netstar -tupln | grep 80)

关掉防火强 service iptables stop

cd /usr/local/nginx/sbin

./nginx

最后去阿里云增加安全组规则8080 0.0.0.0/0 80 443选中

不然打死也访问不了!

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

安装PHP：

1.先安装PHP所需要的必备库
yum install gd zlib zlib-devel openssl openssl-devel libxml2 libxml2-devel libjpeg libjpeg-devel libpng libpng-devel

或者：

yum -y install libmcrypt-devel mhash-devel libxslt-devel

libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel

zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel

ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel

krb5 krb5-devel libidn libidn-devel openssl openssl-devel

//此处为备用选项
yum install -y gcc gdb strace gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs patch e2fsprogs-devel krb5-devel libidn libidn-devel openldap-devel nss_ldap openldap-clients openldap-servers libevent-devel libevent uuid-devel uuid mysql-devel pcre pcre-devel libxslt libxslt-devel openssl openssl-devel

//此处为备用配置
./configure --prefix=/usr/local/php --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-gd-native-ttf --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip --enable-ftp

2.下载PHP：wget http://hk2.php.net/get/php-5.6.30.tar.gz/from/this/mirror
3.解包：tar -zxf mirror
4.进入/usr/local下新建立一个PHP文件夹(mkdir php)，(提示:with-config-file-path是php.ini所在的目录位置)
进入 cd /usr/local/src/php-5.6.30执行以下
./configure --prefix=/usr/local/php \
--with-config-file-path=/etc/php \
--with-gd \
--enable-gd-native-ttf \
--enable-gd-jis-conv \
--enable-mysqlnd \
--with-mysql=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-openssl \
--enable-mbstring \
--enable-fpm

//这是一些常用的库
yum -y install openssl
yum -y install openssl-devel
yum -y install curl
yum -y install curl-devel
yum -y install libjpeg
yum -y install libjpeg-devel
yum -y install libpng
yum -y install libpng-devel
yum -y install freetype
yum -y install freetype-devel
yum -y install pcre
yum -y install pcre-devel
yum -y install libxslt
yum -y install libxslt-devel
yum -y install bzip2
yum -y install bzip2-devel

//执行配置：
./configure --prefix=/usr/local/php --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-gd-native-ttf --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip
//如果有以下错误PHP 编译问题PEAR package PHP_Archive not installed的解决./configure --without-pear  --disable-phar

make
make install
//编译完pear再安装
wget  http://pear.php.net/go-pear.phar
/usr/local/bin/php go-pear.phar

5.编译：make && make install
6.进入 /usr/local/php/etc下复制ini文件作为FPM的进程配置，注意这和php.ini文件是不一样的.
cp php-fpm.conf.defalut php-fpm.conf

此时会多出php-fpm.conf这么个文件.

7. 复制一份php.ini过来,所以去/usr/local/src/php-5.6-30下
cp php.ini-development /usr/local/php/lib/php.ini
这就是以后用到的php.ini文件
8.启动PHP：进入/usr/local/php/sbin
执行 ./php-fpm

(ps aux | grep php查看进程)

以下为卸载php:

首先查看机器上安装的所有php相关的rpm包

rpm -qa | grep php
//这里会列出所有包的列表，要一个个的删除，删除顺序要自己找
//接下来
rpm -e php-cli-5.3.3-49.el6.x86_64
//这是删除CLI的包，如此下去，直到删除完.

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

整合php&nginx

进入nginx 下的conf文件 修改成如下状态

保存再重启动nginx

./sbin/nginx -s reload

　　

mysql下载地址：https://dev.mysql.com/downloads/mysql/5.6.html#downloads

选择 5.6.38   选择linux-Generic   选择all

下载这个：Linux - Generic (glibc 2.12) (x86, 64-bit), Compressed TAR Archive

地址是：wget https://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.38-linux-glibc2.12-x86_64.tar.gz

1.# 安装依赖     yum -y install perl perl-devel autoconf libaio

　　　　　　　　yum install numactl numactl-devel

2.解压：tar zxvf mysql-5.6.38-linux-glibc2.12-x86_64.tar.gz

3.复制 ：cp mysql-5.6.38-linux-glibc2.12-x86_64 /usr/local/mysql -r

4.增加用户组：groupadd mysql        useradd -r -g mysql -s /bin/false mysql

5.安装 ：./scripts/mysql_install_db --user=mysql

6.修改当前目录拥有者为root用户  chown -R root:root ./

7.修改当前data目录拥有者为mysql用户 chown -R mysql:mysql data

8.、修改当前目录(usr/local/mysql)拥有者为root用户  chown -R root:root ./

9、修改当前data目录拥有者为mysql用户  chown -R mysql:mysql data

linux下，在mysql正常运行的情况下，输入mysql提示：
mysql command not found

遇上-bash: mysql: command not found的情况别着急，这个是因为/usr/local/bin目录下缺失mysql导致，只需要一下方法建立软链接，即可以解决：

把mysql安装目录，比如MYSQLPATH/bin/mysql，映射到/usr/local/bin目录下： 
# cd /usr/local/bin
# ln -fs /MYSQLPATH/bin/mysql mysql

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

修改密码

mysql> use mysql;
mysql> UPDATE user SET password=password("test123") WHERE user='root';   
mysql> flush privileges;
mysql> exit;

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

提示登陆权限

mysql>grant all on *.* to root@'%' identified by 'root';

//php -m 无效时设置 /etc/profile环境变量

另外当打印php_info时的扩展与php -m 查到的扩展不一致时，用下which php，会发现路径不一样，所以要去环境变量里增加

方法三：修改/etc/profile文件使其永久性生效，并对所有系统用户生效，在文件末尾加上如下两行代码

PATH=$PATH:/usr/local/webserver/php/bin:/usr/local/webserver/mysql/bin
export PATH

最后：执行 命令source /etc/profile或 执行点命令 ./profile使其修改生效，执行完可通过echo $PATH命令查看是否添加成功。
