installation environment under LNMP – CentOS7

System: CentOS 7 x86_64
NGINX: nginx-1.7.12
Database: mariadb-10.0.13
PHP: php-5.5.23
First, do some preparatory work, first replace centos7 firewall into iptables, can be found in the following links
centos7 changed iptables firewall

After the modified iptables iptables can clean the inside of the filtering rules, and then close the selinux service. Do not forget to remember to install gcc gcc-c ++ wget net-tools and so on, oh.

First install mariadb

It should take a long time to compile the database, so I was already here to download precompiled binary packages, the download version mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz

1. Download the binary package to the next / usr / local / src directory:
[Root @ centos74 ~] # cd / usr / local / src /
[Root @ centos74 src] # wget http://ftp.osuosl.org/pub/mariadb/mariadb-10.0.13/bintar-quantal-amd64/mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz
2, unpack the archive to / usr / local directory:
[Root @ centos74 src] # tar zvxf mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz -C / usr / local /
3. Create mariadb data initialization directory / data / mysql:
[Root @ centos74 src] # mkdir -p / data / mysql
4, add the system user mysql, prohibit the landing system, while the mariadb initialization data directory belongs to the owner and group were changed to mysql:
[Root @ centos74 src] # useradd -r -s / sbin / nologin mysql; chown -R mysql.mysql / data / mysql /
5, rename the extract from the mariadb catalog:
[Root @ centos74 src] # mv /usr/local/mariadb-10.0.13-linux-x86_64/ / usr / local / mysql
6, enter the directory renaming, the initialization mariadb:
[Root @ centos74 src] # cd / usr / local / mysql /
[Root @ centos74 mysql] # ./scripts/mysql_install_db –datadir = / data / mysql –user = mysql

Error: WARNING: The host ‘test4’ could not be looked up with resolveip.
Workaround: vim / etc / hosts in the last line add 192.168.1.242 test4
Error: ./ bin / mysqld: error while loading shared libraries: libaio.so.1: can not open shared object file: No such file or directory
Solution: yum -y install libaio-devel libaio
7. Copy the configuration file to the / etc directory covering before my.cnf:
[Root @ centos74 mysql] # cp support-files / my-large.cnf /etc/my.cnf
cp: whether to overwrite “/etc/my.cnf”? y
8, copy mysql startup script file to the /etc/init.d directory and rename it to mysqld:
[Root @ centos74 mysql] # cp support-files / mysql.server /etc/init.d/mysqld
At the same privileges to modify the startup script to 755:
[Root @ centos74 mysql] # chmod 755! $
chmod 755 /etc/init.d/mysqld
9, edit the startup script to define datadir path:
[Root @ centos74 mysql] # vim /etc/init.d/mysqld
Define data storage path:
datadir = / data / mysql
10, will mariadb comes commands in $ PATH
[Root @ localhost ~] # PATH = $ PATH: /etc/init.d/# currently active on the failure to restart the shell
[Root @ localhost ~] # echo “export PATH = $ PATH: /etc/init.d/” >> / etc / profile
[Root @ localhost ~] # echo “export PATH = $ PATH: / usr / local / mysql / bin /” >> / etc / profile
[Root @ localhost ~] # source! $

11, start mariadb:
[Root @ centos74 mysql] # /etc/init.d/mysqld start
Starting MySQL. SUCCESS!

The second step, to start the installation php

Here first statement about the php installation for Nginx and apache for php installation is different, because the php Nginx is a way to combine the nginx fastcgi, nginx agent can be understood as the php fastcgi, and apache is the php as their own modules to call. The same, php official Download: http://www.php.net/downloads.php
Download php
[Rot @ localhost src] # cd / usr / local / src
[Root @ localhost src] # wget http://am1.php.net/distributions/php-5.5.23.tar.gz
Unzip php
[Root @ localhost src] # tar zxf php-5.5.23.tar.gz
Create relevant account

Workaround: configure: error:. Mcrypt.h not found Please reinstall libmcrypt.
Error: configure: error:. Mcrypt.h not found Please reinstall libmcrypt.
Solution: yum -y install libmcrypt-devel

Install php
[Root @ localhost php-5.3.27] # make && make install
Each of the above steps, if not fully implemented correctly, the next step is not possible, the use of echo $? To see whether the result is “0”, and if not, is not performed correctly.
Modify the configuration file
cp php.ini-production /usr/local/php/etc/php.ini
vim /usr/local/php/etc/php-fpm.conf
The following contents are written to the file:
[Global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
[Www]
listen = /tmp/php-fcgi.sock
user = php-fpm
group = php-fpm
listen.owner = nobody
listen.group = nobody
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
After saving the configuration file, verify the configuration is the correct way to:
/ Usr / local / php / sbin / php-fpm -t
If words such as “test is successful”, explained the configuration is no problem.
Start php-fpm
cp /usr/local/src/php-5.5.23/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
service php-fpm start
If you want it to boot, execute:
chkconfig php-fpm on
Detection is started:
ps aux | grep php-fpm
See if there is a number of processes (probably over 20).

Install nginx

Download nginx
cd / usr / local / src /
wget http://nginx.org/download/nginx-1.7.12.tar.gz
Unzip nginx
tar zxvf nginx-1.7.12.tar.gz
Configuring the Compile Options
cd nginx-1.7.12
./configure \

–with-http_sub_module \
–with-http_gzip_static_module \
–with-http_stub_status_module \
–with-pcre
Error: ./ configure: error: the HTTP rewrite module requires the PCRE library.
Solution: yum -y install pcre-devel
Error: ./ configure: error: the HTTP gzip module requires the zlib library.
Solution: yum install -y zlib-devel

Compile nginx
make
Install nginx
make install

Nginx started to write the script, and added to the system services
vim /etc/init.d/nginx
Write the following:

killproc -p $ NGINX_PID $ NGINX_SBIN -HUP
RETVAL = $?
echo
return $ RETVAL
}

exit $ RETVAL
After saving changes 僿:
chmod 755 /etc/init.d/nginx
chkconfig –add nginx
If you want to boot, execute:
chkconfig nginx on
Nginx configuration change
First, the original configuration files emptied:
> /usr/local/nginx/conf/nginx.conf
“>” This symbol is redirected meaning, alone with it, you can put a text document quickly emptied.
vim /usr/local/nginx/conf/nginx.conf
Write the following:
user nobody nobody;

}

}
After you save the configuration, verify what the configuration file for errors exist:
/ Usr / local / nginx / sbin / nginx -t
If the display reads as follows, is configured correctly, or need to modify the configuration file according to the error message:
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
Start nginx:
service nginx start
If you can not start, see “/usr/local/nginx/logs/error.log” file, check whether nginx start:
ps aux | grep nginx
To see if there are processes.

Test whether to resolve php file

Create a test file:
vim /usr/local/nginx/html/2.php
It reads as follows:
<? Php echo phpinfo ();?>
Test:
[Root @ localhost nginx] # curl localhost / 2.php
Or use the browser to open http: //YourServerIPAddress/2.php

Important: If you can not resolve, check the log was found not connect php, my php version 5.5.23, a relatively new version, you need to add in php / etc / php-fpm.conf file
listen.owner = nobody
listen.group = nobody
These two lines, and then restart the service will be able to use the php
The reason is that this file does not have read permission /tmp/php-fcgi.sock
