prepare to install dependent libraries

Check and install components
yum-y install gcc automake autoconf libtool make gcc-c++ glibc libxslt-devel libjpeg libjpeg-devel libpng l Ibpng-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-devel libidn libidn-devel OpenSSL Openssl-deve L pcre pcre-devel libmcrypt libmcrypt-devel cmake

A few notes:
Pcre, OpenSSL, zlib are required when installing Nginx
CMake is required when installing MySQL

First, view the Linux version of this

[Root@centos src]# cat/etc/issue
CentOS Release 6.7 (Final)
Kernel \ r on an \

second, compile and install Nginx

1. Download Nginx (Stable version)

WGET-P/tmp http://nginx.org/download/nginx-1.8.1.tar.gz

-P Specify download file directory
Or

[Root@centos/]# cd/usr/local/src
[root@centos src]# wget http://nginx.org/download/nginx-1.8.1.tar.gz

Default download to current directory

2, decompression Nginx

[Root@centos src]# Tar xf nginx-1.8.1.tar.gz 
[root@centos src]# cd nginx-1.8.1
[Root@centos nginx-1.8.1]#./ Configure--help (view parameters)

3. Compiling Nginx
If you specify users and user groups, you need to first create

Create user www and user group www
groupadd www
useradd-g www www

./configure--prefix=/usr/local/nginx--sbin-path=/usr/sbin/nginx--user=www--group=www--with-http_ssl_module-- With-http_gzip_static_module

5. Configuration support PHP

    cd/usr/local/nginx/conf
    vi  nginx.conf
    user   www  www;  #修改nginx运行账号为: www user
    index  index.php index.html index.htm;   #增加index. PHP location

     ~ \.php$ {
        root           html;
        Fastcgi_pass   127.0.0.1:9000;
        Fastcgi_index  index.php;
        Fastcgi_param  script_filename   $document _root$fastcgi_script_name;
        Include        fastcgi_params;
  }
     #取消FastCGI the comment for the server section location, and note the parameters of the Fastcgi_param line, change to $document_root$fastcgi_script_name, or use the absolute path

    // Verify Nginx configuration Syntax 
    cd/usr/local/nginx
    ./sbin/nginx-t

    //test
    cd/usr/local/nginx/html
    vim index.php 
    //contents are as follows
     <?php phpinfo ()?>
    //If the environment information of PHP can be displayed, the configuration is successful.

6. Virtual Host Settings
Here you use multiple. conf method Configurations
This is the time to put the project in the WWW directory, the corresponding domain name is onethinkcms.com
The downloaded items are placed under/www/onethinkcms
Open/usr/local/nginx/conf/nginx.conf
Add the following line at the end

# The configuration file containing all the virtual hosts is added in the Conf directory under the new vhosts directory to add the corresponding. conf profile

include vhosts/*.conf;

Create a new directory under/usr/local/nginx/conf

mkdir vhosts cd vhosts vim onethinkcms.conf//Add the following configuration server {Listen 80;

        server_name onethinkcms.com www.onethinkcms.com;

         Access_log/www/onethinkcms.log;

             Location/{root/www/onethinkcms;

        Index index.php index.html index.htm;

      } # Error_page 502 503 504/50x.html;

      # location =/50x.html {# root/usr/share/nginx/html; #} # Pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~. php$ {# here
            The value corresponds to the $document_root root/www/onethinkcms;

            Fastcgi_pass 127.0.0.1:9000;

            Fastcgi_index index.php;

            #注意这里的路径 Fastcgi_param script_filename $document _root$fastcgi_script_name;

        Include Fastcgi_params; }
}

Configuring the Hosts File
Vi/etc/hosts Add 127.0.0.1 onethinkcms.com
Re-start Nginx
Visit onethinkcms.com to

7. Install MySQL

① Download MySQL
MySQL official website->downloads->community->mysql Community server-> drop-down box select source Code

CD/USR/LOCAL/SRC wget
Http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.30.tar.gz

② Installing the tools and libraries needed to compile the source code
If the CMake library is missing

Yum install CMake (can download source code from http://www.cmake.org and compile installation) (Installation package installation cmake)
wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz
TAR-XZVF cmake-2.8.10.2.tar.gz
./bootstrap Make Make
Install

③ setting up MySQL users and groups

New MySQL user group Groupadd MySQL
New MySQL user useradd-r-g MySQL MySQL

④ the directory needed to create a new MySQL

New MySQL installation directory mkdir-p/usr/local/mysql
New MySQL database data file directory Mkdir-p/data/mysqldb

⑤mysql Source Package Decompression

Cd/usr/local/src
Tar zxvf mysql-5.6.27.tar.gz
CD CD mysql-5.6.27

Cmake-dcmake_install_prefix=/usr/local/mysql
-dmysql_unix_addr=/usr/local/mysql/mysql.sock-ddefault_charset=utf8-ddefault_collation=utf8_general_ci-dwith_ Innobase_storage_engine=1-dwith_myisam_storage_engine=1-dwith_memory_storage_engine=1-dwith_partition_storage_ Engine=1-dmysql_datadir=/data/mysqldb-dmysql_tcp_port=3306-denable_downloads=1-dextra_charsets=all-denabled_ Local_infile=1-dwith_readline=1
(Note: Re-run the configuration, you need to delete the CMakeCache.txt file rm CMakeCache.txt) make make install

⑥ modifying MySQL directory Owners and Groups

Modify the MySQL installation directory Cd/usr/local/mysql chown-r Mysql:mysql.
Modify the MySQL database file directory cd/data/mysqldb chown-r mysql:mysql. (Note the following. refers to the current directory)

⑦ initializing MySQL Database

Cd/usr/local/mysql
./scripts/mysql_install_db–user=mysql–datadir=/data/mysqldb

⑧ Copy the MySQL service startup configuration file

Cp/usr/local/mysql/support-files/my-default.cnf/etc/my.cnf
(Note: Overwrite if the/etc/my.cnf file exists.) ）

⑨ copy MySQL service startup script and join path path

CP Support-files/mysql.server/etc/init.d/mysqld

⑩ start the MySQL service and join the boot-up

Service mysqld Start
Chkconfig–level mysqld on

⑪ Check if the MySQL service is started

NETSTAT-TULNP | grep 3306
MySQL needs to be added to the environment variable Vim/etc/profile
At the end, add the following command
Mysql_home=/usr/local/mysql
Path= $MYSQL _home/bin: $PATH
Export PATH Mysql_home
Source/etc/profile
Mysql-u root-p (password is empty, if you can log on, the installation is successful)

⑫ Modifying the password of the MySQL user root

Method One: Mysql-u root-p
Use MySQL
Update user set Password=password (' 123456 ') where user= ' root '
Flush privileges (Refresh permissions)
Method Two:/usr/local/mysql/bin/mysql_secure_installation
(Modify the password for the MySQL user root, and disable root remote connection, remove test database and anonymous user.) ）

⑬ errors that may occur
Error one: Starting MySQL. The server quit without updating PID file ([failed]/mysql/server03.mylinux.com.pid).
FIX: Modify/etc/my.cnf in DataDir, point to correct MySQL database file directory

Bug Two: Error 2002 (HY000): Cannot connect to local MySQL server through socket '/tmp/mysql.sock ' (2)
Workaround: Create a new link or add the-s parameter to MySQL to directly indicate the Mysql.sock location. Ln-s/usr/local/mysql/data/mysql.sock/tmp/mysql.sock
/usr/local/mysql/bin/mysql-u root-s/usr/local/mysql/data/mysql.sock

Error three:-bash:mysql:command not found (you can also add environment variables directly)
FIX: Because the path of the MySQL command is under/usr/local/mysql/bin, so when you use the MySQL command directly, the system checks the command under/usr/bin, so I can't find the
Ln-s/usr/local/mysql/bin/mysql/usr/bin make a link

summary of issues encountered during installation configuration
1. PDO connection Error sqlstate[hy000] [2002] No such file or directory caused by:pdoexception

    Mysqli.default_socket =/usr/local/mysql/mysql.sock

Restart PHP-FPM Service PHP-FPM restart

2, port and firewall issues
Configure the firewall to turn on 80 ports, 3306 ports
Vi/etc/sysconfig/iptables
-A input-m state–state new-m tcp-p tcp–dport 80-j ACCEPT (allow 80 ports through the firewall)
-A input-m state–state new-m tcp-p tcp–dport 3306-j ACCEPT (Allow 3306 ports through the firewall)
Special Note: Many netizens add these two rules to the last line of the firewall configuration, causing the firewall to fail to start, the correct one should be added to the default 22 port under this rule
After adding the firewall rules as follows:

*filter
: INPUT accept [0:0]
: FORWARD accept [0:0]
: OUTPUT accept [0:0]
-A input-m State--state Establis  Hed,related-j Accept-
a input-p icmp-j accept
-a input-i lo-j ACCEPT
-a input-m state--state new-m TCP -P TCP--dport 22-j accept
-a input-m state--state new-m tcp-p TCP--dport 80-j accept
-a input-m state-- State new-m tcp-p TCP--dport 3306-j ACCEPT
-a input-j REJECT--reject-with icmp-host-prohibited
-a FORWARD- J REJECT--reject-with icmp-host-prohibited
COMMIT
/etc/init.d/iptables restart  #Finally restart the firewall to make the configuration effective

View firewall status
/etc/init.d/iptables status
Turn off SELinux

Vi/etc/selinux/config
#SELinux = forcing? Comment out
#Selinuxtype = targeted? Commented out
SELinux = disabled
: Wq  Save, close
Shutdown-r now? Restart the system

PHP command could not find a problem

① can be installed via yum install PHP-CLI (PHP-CLI version is lower)
Yum Remove Php-cli

②bash:php:command not found
Solve:
Export path= $PATH:/usr/local/php/bin
Then, Echo $PATH look, and see.
Usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/php/bin
At this time, you can directly in any directory of the system php-i can be executed

Installing PHP Extensions
① in the PHP source package to find the appropriate extension
Cd/usr/local/src/php-5.6.13/ext/pdo

② is executed under this directory
/usr/local/php/bin/phpize

③ execution
./configure–with-php-config=/usr/local/php/bin/php-config
Make & make Install

④ Open php.ini File
cd/usr/local/php/lib/
Join extension=pdo.so

⑤ Restart PHP-FPM
Service PHP-FPM Restart

If you encounter a problem such as the absence of ' Mysql_driver.lo ' is a valid Libtool object
Clear the compiled file make clean or remove the PHP installation package, re-unzip the new
