One 、 Source code installation nginx

1. Compilation environment, such as gcc and gcc-c++ compiler ,make

2. Prepare the software ： nginx-1.18.0.tar.gz

Deploy Nginx

install nginx Source code compilation , Required dependency package ：

[root@tiehao ~]# yum -y install gcc gcc-c++ make zlib-devel pcre pcre-devel openssl-devel

Package description ：

gcc c Language compiler .

gcc-c++ c++ Language compiler .

make be used for configure and make Compiled tools .

zlib :nginx Provide gzip Compress modular , need zlib Library support .

pcre The purpose of the package is to make nginx regular expression , Address rewrite rewrite

openssl-devel : Give Way nginx Provide ssl function .

a key , a key 、 Key if there is no... In the folder configure file , The required steps are as follows ：

yum -y install autoconf

autoreconf  Generate configure file

Start installation ：

Source code compilation 3 Axe ：./configure , make ,make install

[root@tiehao ~]# tar xvf nginx-1.18.0.tar.gz

[root@tiehao ~]# cd nginx-1.18.0

[root@tiehao nginx-1.18.0]# ./configure --prefix=/usr/local/nginx

[root@tiehao ~]# make -j 4  （4 Kernel compilation , According to the actual situation cpu Check the number ）

[root@tiehao ~]# make install

3. Detailed source code installation 3 Axe To configure (configure)、 compile (make)、 install (make install)

# ./configure

a. Specify installation path , for example --prefix=/usr/local/nginx

b. Enable or disable a function , for example --enable-ssl,--disable-filter

c. Associated with other software , for example --with-pcre --with-http_ssl_module

d. Check the installation environment , For example, whether there is a compiler gcc, Whether to meet the software dependency requirements

The resulting ：Makefile

# make -j 4 # Compile the source code file into an executable binary file , Press Makefile File compilation ,

Use -j 4 Appoint 4 The core CPU compile , Speed up

# make install # Press Makefile Define the file path to install

# make clean // Clear the last time make The command produces object and Makefile file . Use scenarios ： When reconfiguration is required, execute configure when , It has to be executed first make clean. as follows ：

[root@tiehao nginx-1.18.0]# make clean ( Just clear the previous executable and configuration files )

rm -rf Makefile objs

[root@tiehao nginx-1.18.0]# ./configure --prefix=/usr/local/nginx  # Reconfigure

4. Delete source code package ：

installed , Delete source code package ：

Sometimes the deletion is not clean , So we suggest that when you install , stay configure Step add a ： --prefix Parameters . When deleting or backing up in this way , Directly to delete --prefix The specified installation directory operation is OK .

[root@tiehao ~]# rm -rf /usr/local/nginx/

Two 、 Source code compilation error 5 A perfect solution

[root@teihao extundelete-0.2.4]# tar xvf extundelete-0.2.4.tar.bz2

[root@tiehao ~]# cd extundelete-0.2.4

# Installation solves the dependency .

[root@tiehao extundelete-0.2.4]# ./configure # Check the system installation environment

Configuring extundelete 0.2.4

configure: error: Can't find ext2fs library

After the source code compilation error , Common solutions ：

common 5 Methods

Method 1：

[root@tiehao ~]# mount /dev/sr0 /mnt

[root@tiehao Packages]# cd /mnt/BaseOS/Packages

[root@tiehao Packages]# rpm -ivh ext2fs

# Switch to the path where the local software package is located , Press two tab key . General situation ,ext2fs It starts with the name of the package to be installed .

If there is Automatic completion

Method 2：[root@tiehao Packages]# ls *ext2fs* # Find the complete keyword

Method 3：[root@tiehao Packages]# ls *2fs* # Find some keywords

Method 4: Ultimate trick

Method 5: Use yum Search for , This method is recommended

[root@tiehao Packages]# yum search 2fs #centos7 Easy to use in

Installation Library ：

[root@tiehao ~]# cd /mnt/BaseOS/Packages/

[root@tiehao Packages]# rpm -ivh e2fsprogs-libs-1.45.6-1.el8.x86_64.rpm

Verifying... ################################# [100%]

Preparing... ################################# [100%]

package e2fsprogs-libs-1.45.6-1.el8.x86_64 is already installed

Interaction ： This shows that the library has been installed , however configure I said I couldn't find . What do I do ？

solve ： Library installed , It shows that it can't be found . This situation ： You need to install the development files of the library

[root@tiehao Packages]# rpm -ivh e2fsprogs-devel-1.45.6-1.el8.x86_64.rpm

devel = development ( Development )

error ： Dependency detection failed ：

libcom_err-devel(x86-64) = 1.45.6-1.el8 By e2fsprogs-devel-1.45.6-1.el8.x86_64 need

[root@tiehao Packages]# ls libcom_err-devel*

[root@tiehao Packages]# rpm -ivh libcom_err-devel-1.45.6-1.el8.x86_64.rpm

or

[root@tiehao extundelete-0.2.4]# yum -y install e2fsprogs-devel.x86_64

Expand ： skill

see rpm Files generated after package installation ：

[root@tiehao Packages]#rpm -qpl e2fsprogs-devel-1.41.12-11.el6.x86_64.rpm |more

notes ： You can see a lot of .h Final document , These files are called header files . With these header files , ./configure adopt .h Headline

Pieces of , To find the corresponding library file . So library files and devel All development packages must be installed .

[root@tiehao extundelete-0.2.4]# ./configure

Configuring extundelete 0.2.4

Writing generated files to disk

It's settled ,ext2fs The problem of missing library files , There are no compilation and installation steps here , because extundelete Only in

centos6 Lower installation .

summary , Features of software installation method ：

rpm＋yum： convenient , The software version is low . Good stability 、 Easy to manage . Poor performance .

Source code compilation and installation ： trouble , The software version is new , Can be customized . Slightly less stable 、 The management is a little poor . Good performance .

Source code compilation and installation ： Mainly installation LAMP or LNMP Architecture , We will use
